10 | NOVEMBER 2021WWW.MPTMAG.COMMPTCASE STUDIESCASE STUDIESEstablished in 1928 by the California legislature, with the goal to bring water from the Colorado River to southern sections of the enormous state, the Metropolitan Water District of Southern California has come a long way since it began operation in 1941. Work began in 1931 after voters approved a $220 million bond issue for construction. After decades of wrangling with water issues, leaders in the region believed the new agency could offer a long-term solution towards solving those challenges.The project was enormous—35,000 workers laboring 24/7 in desert heat, constructing four dams, five pumping plants, blasting 90-plus miles of tunnels and establishing 150 miles of canals, siphons, and pipelines. Workers at the Weymouth Treatment Plant turned the first valve to deliver water to Pasadena on June 17, 1941. Water flowed to Beverly Hills, Burbank, Compton, and Santa Monica the following month, as they were among the thirteen original cities included in the original district.Now, more than nineteen million people rely on water from the district. Its facilities serve residents that reach across 5,200 square miles, including parts of Los Angeles and San Diego. It is the largest supplier of treated water in the United States, and taps into fourteen cities, eleven municipal water districts, and one county water authority. The region’s population relies on district water, and a recently completed $38.5 million project at its Robert W. Diemer Water Treatment Plant in Yorba Linda will help ensure continuity of service.HUGE OUTPUTThe Diemer treatment plant began operations in 1963 but has not made any significant upgrade in CALIFORNIA PROJECT TAKES AIM AT EFFICIENCYAfter years of neglect, a $38.5 million project will help keep the Robert Diemer Water Treatment Plant running BY THOMAS RENNERPhoto credit: RevepixThe Robert B.

NOVEMBER 2021 | 11WWW.MPTMAG.COMMPTimprovement since that time. It is one of five water treatment plants in the extensive Metropolitan Water District Network, and has a treatment capacity of 520 million gallons per day, and delivers water via gravity flow to Los Angeles and Orange counties. The facility is one of the largest in the nation, and has the capability to meet the needs of approximately three million people that live in the region. Water entering the 212-acre plant comes from two sources, a 440-mile aqueduct that is part of the California state water project and a 242-mile aqueduct that funnels water from the Colorado River.Water is treated to meet or exceed federal and state drinking water regulations. Using advanced treatment technologies, increased monitoring and adhering to the stringent laws and guidelines, the process ensures the water quality meets government standards. The Met performs about 250,000 water quality tests each year.“Water was not being wasted,’’ says Eber Luquin, project engineer for Environmental Construction, which dismantled the existing equipment and installed new components. “The equipment simply was not as efficient as it once was and water quality could be improved. The old, submerged mechanical equipment was coated in tar and some sealants used contained PCB properties.”The project started in November 2018 and was completed in March 2021. Due to COVID-19 and other weather delays, the project took about four months longer than anticipated to complete.Photo credit: RevepixThe project included the installation of ten stainless steel floor doors manufactured by BILCO.

12 | NOVEMBER 2021WWW.MPTMAG.COMMPTCASE STUDIESCASE STUDIESREPLACING COMPONENTSDue to the age of the facility and minimal replacement over the years, nearly every component needed to be replaced. That included flocculators, baffle walls, clarifier, effluent launders, drop gates, Weir gates, inlet gates, pipes of various sizes and material, sludge pumps, valves ranging from one-half inch to 42 inches, Smith Blair couplings, Victaulic couplings, and manual and electric actuators. Workers also strengthened a filter control building, including reinforcement of interior concrete frames and filter decks, and construction of new concrete shear walls. Teams also replaced 128 high-performance, rubber-lined butterfly valves and actuators, and replaced or modified structural support components, piping, mechanical equipment, handrails, and lights. Some hazardous material abatement was also required.The expansive project scope and size of the facility posed some unique challenges for engineers. One task confronting Luquin’s team was installing effluent launders, where workers needed to solve issues regarding access and load restrictions at certain areas of the plant. Launders are an important part of the treatment process, as they help prevent waste materials from ending up in the water. “We designed large crane pads that would not exceed 1,500 psi (ground bearing pressure) with our given loads so that we could install launders,’’ Luquin says. Teams also faced access issues in constructing concrete shear walls. “The shear walls were constructed in four quadrants underneath the filter beds and access was very restricted to each location,’’ Luquin says. “There was only ingress and egress. We had to get all of our materials through a small opening, 5-feet by 6-feet, and then had a 15-foot drop. This was considered a confined space, so we had many OSHA regulations to comply with.”PROJECT AT A GLANCEWHAT:A $38.5 million renovation of the Robert B. Diemer Water Treatment Plant in Yorba Linda, California. The treatment plant is part of the Metropolitan Water District of Southern California.WHY:The treatment plant began operation in 1963, but many components had not been upgraded or replaced. The treatment plant, which has a capacity of 520 million gallons per day, is one of the largest in the nation and helps meet the water needs of nearly three million people. PROJECT SCOPE:Replaced flocculators, baffle walls, clarifier, effluent launders, drop gates, Weir gates, inlet gates, pipes of various sizes and material, sludge pumps, valves ranging from 1/2 to 42 inches, Smith Blair couplings, Victaulic couplings, and manual and electric actuators. Teams also stabilized a filter control building, including reinforcement of interior concrete frames and filter decks, and constructed new concrete shear walls. FLOCCULATOR ACCESS:Ten single- and double-leaf floor doors from BILCO were included in the project. The corrosion-resistant doors allow access to flocculator equipment. Flocculators are key of equipment that help determine the amount of treatment water needs and the sequence in which chemical agents should be added.DID YOU KNOW?

NOVEMBER 2021 | 13WWW.MPTMAG.COMMPTACCESSING FLOCCULATORSIn any water treatment plant, flocculators are key pieces of equipment that help determine the amount of treatment the water needs and the sequence in which chemical agents should be added. Readings from the flocculators can help water treatment plants operate efficiently. Flocculation is also essential in keeping the water supply clean.Treatment plant workers will access this important equipment through floor access doors manufactured by The BILCO Company. BILCO products are frequently used at water treatment plants due to their corrosion resistance and safe, reliable operation.“BILCO hatches were selected due to their dependability and reputation with the plant,’’ Luquin says. “The fact that these hatches are made with quality stainless steel material to the dimensions we required and have a drain port built in were important features.”Corrosion, especially at water treatment plants, can dramatically reduce the life of floor doors and other equipment. The ten BILCO floor doors used on this project feature stainless steel construction and hardware to withstand the corrosive environment at the facility. The doors also feature BILCO’S engineered lift-assistance to ensure safe and easy one-hand operation, automatic hold open arms, and positive latching mechanisms for security.CONTINUAL CONCERNSWater in California is a treasured resource. Efficiency and resourcefulness are paramount for the five treatment plants and the three major water reservoirs of the district. The massive renovations at the Diemer facility will help ensure that. “I think it’s an essential lifeline for the people in Southern California,’’ Luquin says. “The supply from the Metropolitan Water District is a vital resource for smaller districts in the region. This project will help the system maintain peak efficiency.” THOMAS RENNER writes on building, construction, engineering and other trade industry topics for publications throughout the United States. Almost every part of the plant was upgraded with new equipment. The plant opened in 1963 but most equipment had not been upgraded or replaced. Photo credit: Revepix

NOVEMBER 2021 | 15WWW.MPTMAG.COMMPTWhen pumps fail, site managers have to manage consequences like downtime, maintenance, and damage—as well as sewage overflow in the case of wastewater pump failures. Knowing the most common causes of pump failure can help you avoid these consequences. By implementing maintenance plans that mitigate these failure causes, it’s possible to keep pumps running for as long as possible.COMMON CAUSES OF FAILURE IN WASTEWATER PUMPSWhile pumps can fail in a wide variety of ways, there are a few common manners in which pumps tend to malfunction. Cavitation in pumps is the rapid creation and collapse of air bubbles in pumped fluid. This occurs when the net-positive suction head available (NPSHa) is lower than the net-positive suction head required (NPSHr), meaning the pressure on the pump fluid has dipped below its vapor pressure. Air bubbles form in low-pressure areas of the pump, typically near the eye of the impeller, then collapse as they move to higher-pressure areas, often at some point along the impeller vane.Pump cavitation causes damage—primarily to mechanical seals and bearings—and a reduction in pump performance. The NPSH margin needed to prevent cavitation varies depending on the particular pump and how it’s being used. On average, NPSHa will need to be around four times greater than the NPSHr—but the needed NPSHa can be anywhere between 2 and 20 times greater than NPSHr.Fouling is another common pump issue for wastewater facilities. Over time, particulate matter from pumped fluid can accumulate to water pump flow path surfaces. Hard water tends to cause scaling, or the buildup of minerals, while wastewater and seawater may cause the creation of biofilms. Fouling may begin soft and then harden over time, meaning early detection and proactive monitoring of pumps may make fouling easier to fix.PREVENTING CORROSION OR WEAR AND TEARCorrosion of pipes and pump materials will occur over time due to chemical reactions between the pumped fluid and exposed metal surfaces. While some corrosion is inevitable, pumping fluid and system management can sometimes accelerate the pace of corrosion, resulting in earlier-than-expected pump failure or other problems.Choice of pipe material can also help to slow the rate of corrosion. Cast iron, for example, is a popular choice of pump material but may corrode readily HOW TO AVOID WASTEWATER PUMP FAILURESIdentifying key causes of failure helps prevent costly consequences BY EMILY NEWTON

Page 20

16 | NOVEMBER 2021WWW.MPTMAG.COMMPTWATER & WASTEWATER FOCUSWATER & WASTEWATER FOCUSwhen exposed to low-pH pumping fluid. Stainless steel is more expensive than other materials but is resistant to corrosion under a wide range of operating conditions. Depending on the composition of wastewater and pump fluid, cast iron may be an acceptable choice. Knowing the conditions your pumps will be under and choosing a material to match will help reduce the speed of corrosion.Natural wear and tear can also eventually lead to pump failure. Regular maintenance checks and scheduled repairs can help you or your team identify when parts need to be replaced due to wear, helping avoid premature pump failure. Maintenance methods that take advantage of real-time conditions monitoring technology, like networked sensors monitoring pump pressure and similar variables, may help workers identify excessive wear and tear before it causes failure.Certain operating conditions can increase wear on pumps, accelerating the failure of pump components. For example, particulate matter in pumped water can both cause fouling and speed up the pace of wear on a pump. Pumps exposed to especially corrosive or fouling pump fluids may need more frequent maintenance than other pumps.LOOKING BEYOND THE PUMP Because pumps are so critical to wastewater systems, post-incident reviews and repairs often focus directly on the pump, sometimes at the expense of other system components. Often, pump failure isn’t a result of issues with the pump itself—instead, other equipment like power supplies or piping. For example, voltage unbalance and excessive head pressure are two common causes of failure or malfunction in pumps, leading to mechanical stress and cavitation respectively.Working backwards from pump failures, identifying how the pump failed and how the system’s operation may have caused the failure, is a good way to prevent future malfunction. Simple measurements, like power and flow meter readings, can provide key information—like voltage and the actual flow rate of a given pump—that can reveal potential pump issues. Information from equipment like pump relays can be similarly helpful.A maintenance plan that includes regular monitoring of pump and system conditions will offer more chances for catching issues like voltage imbalances and excessive or insufficient pressure.BEST PRACTICES FOR AVOIDING PUMP FAILURERegular maintenance and knowledge of common pump failure causes will go a long way in helping you prevent pump failure. If you already have an effective maintenance plan in place, condition monitoring and system audits are a good next step. A variety of condition monitoring platforms are available. Many manufacturers of pumps and pump control systems offer proprietary SCADA systems that monitor wastewater levels, providing early notice on malfunctions or failures.Some wastewater treatment facilities also use networked sensors to provide real-time operational monitoring. These sensors continuously gather and report information on pump conditions, providing a remotely accessible window into a pump’s current performance and health. System audits should investigate operating conditions and components that commonly cause pump failure. For example, re-evaluating a pump performance curve during an audit can provide valuable information that may help prevent future pump failures. As system conditions change—sediment builds up, scaling occurs, and air is trapped in pipe corners—the pump performance and system curves can change. Repairs, retrofits, and regular maintenance based on pre-existing or legacy pump curves can cause trouble down the line, like oversized replacement pumps.These oversized pumps can cause serious noise and vibration, jostling flanged pipes and connections loose or fatiguing pipe welds over time. Ensuring that data on pumps and site systems are up-to-date and accurate will help you avoid problems like these.TECHNIQUES FOR AVOIDING WASTEWATER PUMP FAILUREWastewater pump failure can have serious consequences for a facility—including unplanned downtime, high maintenance costs, and sewage backup. Avoiding pump failure can be simple—regular maintenance and condition monitoring are good ways to detect issues like corrosion or severe wear and tear before they cause problems. System audits and reviews can help catch more complex problems—like an oversized pump that is starting to cause pipe damage.EMILY NEWTON is a technology and industrial journalist.

Deciding which water mains to replace took 75 percent less time than in the past, while also reducing unnecessary capital costs and water loss from pipe failures. A HUGE CHALLENGE“Based on what we’ve seen with Xylem’s predictive modeling services, we are confident that replacing these mains is the best bang for the buck,” says Adam Haggerty, asset manager for Raleigh Water. “This is a game changer for us, and it is something we will be able to use for a wide variety of applications.”It’s a huge challenge to manage risk in a big pipe network. You have to predict failure in an asset you can’t see, knowing the pieces were built at different times in different ways. Get it wrong and you replace some pipes prematurely, while leaving higher-risk parts of the network in place. So, getting it right with advanced risk analytics gives the utility more confidence, saves the community money, and enables you to dig only when you have to.“This is a great result for Raleigh Water, demonstrating the power in combining geographic information system data with insight into the water network, says Christa Campbell, director industry solutions: water, Esri. “We’re so pleased that, together, Esri and Xylem are bringing actionable new decision intelligence that delivers real savings by targeting work in the city where the need is greatest.”USING HISTORICAL DATA FOR FUTURE SUCCESSXylem’s Asset Performance Optimization solution analyzed the utility’s entire network, combining historical pipeline break data with information from Raleigh Water using Esri ArcGIS Enterprise. The resulting assessment identified the top 1 percent of at-risk pipeline segments, scattered throughout the city, based on their probability of failure. The team then clustered groups of at-risk pipes to be prioritized for more targeted preventative maintenance. The data-driven risk model also supports a city-wide initiative to increase racial equity by eliminating bias from selection of infrastructure projects. To date, Raleigh Water has planned six projects using the results of Xylem’s analyses. It estimates the work with Xylem has already saved the utility 75 percent of planning time while reducing risk to the network, decreasing response times, and lessening community impact of breaks that might occur.

20 | NOVEMBER 2021WWW.MPTMAG.COMMPTMAINTENANCE & RELIABILITYMAINTENANCE & RELIABILITYEnvironmental remediation projects can take months to years of around-the-clock extraction of pollutants to clear water and soil of contaminants from accidents such as storage tank leaks, chemical spills and waste discharge. Remediation site managers face many challenges, such as meeting project goals, controlling costs, keeping the site running, and protecting the environment. At the top of the list of responsibilities is meeting regulatory requirements. Federal, state or local regulators can fine operators if the site becomes nonoperational for a period of time during an unplanned shutdown. Incorporating remote monitoring technology into the process can increase efficiency because managers are alerted immediately of potential equipment malfunction and environmental changes that can halt the operation. These monitoring systems provide an easy, affordable way to receive actionable information to keep equipment running, reduce downtime, and avoid costly fines. With a monitoring system, managers can keep 24/7 watch on the performance of key equipment components and receive instant notification if sensor readings move outside of the required parameters. They can also access real-time and historical data, log information, look for trends that could indicate a problem and generate records for regulatory reports. HOW REMOTE MONITORING WORKSRemote monitoring systems are installed at both staffed and unattended sites to monitor conditions around the clock. This reduces the need for constant staffing and helps to avoid unnecessary or time-consuming visits to the site to check the status of the remediation equipment. A monitoring system consists of a base unit that constantly collects data from existing equipment or sensors placed at key points at the site. The number of external sensors used depends on the number of inputs on the base unit. Users program the devices to specify the desired high or low parameters on the monitored sensors. The base unit contacts designated personnel when a sensor reading moves out of the preset limits. Managers can receive these notifications via phone, email, or text. Most remediation sites have a SCADA, PLC, or control panel locally monitoring and controlling the operation of the site. Advanced remote monitoring systems can seamlessly integrate into a panel or SCADA system that supports Modbus RS485 and TCP IP.

They can integrate the monitoring system into floats, pump alarm outputs, level transducers, and other equipment. They can also connect external sensors to monitor temperature fluctuations, flow rate, power failure, and security breaches.CONNECTIVITYMonitoring systems that are robust enough to handle the demands of a remediation site require an internet or wi-fi connection and access to an electrical outlet to power them. But for areas that do not have an internet or cellular connection, satellite systems are available. Cellular systems need to be registered on a wireless network like Verizon or AT&T in order to send or receive messages.

The systems use satellite technology to provide virtually unlimited coverage throughout the United States and many other countries without relying on telephone lines, Ethernet connections, or cellular networks. They can operate in a wide range of temperatures without any effect on battery life. Site managers can access information and make programming changes via the system’s dedicated website. Cloud-based monitoring systems can monitor, deliver alarms and log input/output point data from third-party Modbus sensors, transducers, and PLCs. This enables site managers to remotely access the values pulled from Modbus equipment or external sensors at all their remediation sites from a user-friendly dashboard using an app or website. A cloud-based unit monitors itself by constantly sending a signal to the cloud to confirm the system is online. If the internet connection is lost or there is a cellular communications problem, the system sends an alert to designated users via phone, text, or email. Managers do not have to worry about losing data if the cloud connection is interrupted because all information gathered during this time is stored in the device and will be uploaded to the cloud when the connection is restored. DATA LOGGING AND REPORTING In addition to providing remote monitoring of remediation equipment, these systems automatically log the data required for compliance reports because they are equipped with data acquisition functionality that provides real-time and historical information on equipment performance. They collect and record precise data, including flow rates, run times, and operational standards required for environmental remediation reporting. Essential data to log includes blower runtimes, pilot and flare temperatures, liquid or air flow totals, shutdown and startup events, and VOC levels. ADDING IT UPSite remediation is complex, and any unexpected stoppage of the process can have serious environmental and regulatory consequences. However, constant monitoring of equipment and conditions is not complicated or expensive. Using the right remote monitoring system for the scope and specs of the remediation site gives site managers early warning of a potential problem, so they can respond quickly to avert a significant malfunction.

NOVEMBER 2021 | 25WWW.MPTMAG.COMMPTWhen first learning about air-operated double-diaphragm (AODD) pumps, many people are left asking how they are able to excel in so many diverse applications. The success in this enormous application range, and consequently the popularity of AODD pumps, lies in the pump’s design characteristics. These characteristics include:• Simple startup• Self-priming capability• Resistant to dry running and runs smoothly with solids• Gentle displacement pumping• Continuously adjustable via controllable air volumes• Self-adjusting when the medium changes• No drives or rotating parts in the pumped medium• No shaft seals• Overload-proof—if the counter-pressure equals the drive-air pressure, the pump stops and restarts when the pressure drops—without regulation or monitoring via mean supply response time (MSRT) devices• Easy to use in ATEX areas• Current-less drive via compressed airThe first two characteristics—simple startup and self-priming—help explain why AODD pumps are so flexible. Part of this flexibility includes easy installation. Since there is no need to align the pump when changing locations, installation can be performed by simply standing the pump upright and connecting the fluid lines and air supply. And unlike other types of pumps, there is no need to prime an AODD pump. Therefore, rather than the laborious and, depending on the liquid, dangerous process of bringing the medium into the pump manually, the pump simply fills itself during operation by sucking the medium out of the receiver.SIMPLICITY IN ACTIONOnce in operation, an AODD pump is not only easy and simple to control, it also does not require any control electronics and/or expensive frequency converters, which might cause the motor temperature to rise during slow running without a forced cooling fan (critical for ATEX). Instead, the air volume and the pump flow rate are simply regulated with a needle valve. In addition, if, for example, the density or viscosity changes due to the temperature, the pump will automatically run slower or faster without damage to the pump or without the loss of liquid, as is the case with internal pump slip or a magnetic coupling that can tear during operation. And if the liquid fails to flow, for example, because the tank is empty, it simply continues to run dry.

26 | NOVEMBER 2021WWW.MPTMAG.COMMPTPUMP SOLUTIONSPUMP SOLUTIONSREDUCING RISKS THROUGH GENTLE HANDLINGAnother important design characteristic of the AODD pump is gentle displacement pumping. This characteristic stems from the fact that these pumps allow solids of considerable size to pass through them, resulting in very gentle pumping and low shear. And because AODD pumps do not contain any drive parts or other rotating parts within the fluid, there is no need to worry about damaging the shaft seal. Operational risks and the need to maintain mechanical seals (including the use of additives for flushing, etc.) are also eliminated. Instead, a purely static seal takes effect, which is “hermetically sealed” according to guidelines from the German Technical Guidelines on Air Pollution.It’s also important to mention that an AODD pump is overload-proof. This means that the pump can only build up as much pressure as you give it via the drive air pressure, which, for example, can be the maximum permissible pressure of your filter. If the outlet pressure reaches the drive air pressure, the pump simply stops, meaning that there is no danger of the pump or the line bursting if the pressure line is blocked. This results in overload protection for lines/filters and a simple on-off operation via valves in the medium.There is not a risk of sparks from an electric drive, also self-heating is not an issue, and static charges can be dissipated via the pump’s conductive materials (as well as plastic). This also makes AODD pumps ideally suited for use in hazardous areas (ATEX) and mobile applications. Light and compact, these pumps are also simple to install in hazardous areas and can even operate with stored air in the case of an emergency.HIGH PERFORMANCE AND HIGHLY ADAPTABLE Another key characteristic of an AODD pump is its enormous range of pump materials and their possible combinations. The interior of an AODD pump can be manufactured in a large number of elastomers and thermoplastics, from “black rubbers” such as neoprene or Buna-N to PTFE. The pump’s housing can be manufactured in various metals, ranging from cast iron and aluminum to high-grade stainless steels. The housing can also be manufactured in a variety of plastics, including high-performance plastics such as PTFE or PEEK. Therefore, depending on the mechanical/chemical properties or the temperature of the medium, the pump can almost always adapt to the application. And the fact that the pump is constructed in a solid-block design also provides additional design advantages when it comes to safety, including high stability and rigidity, static weight, and smooth and highly chemical-resistant surfaces.MAKING THE AODD CHOICEIn conclusion, if you’re looking for a pump that is flexible; simple to start up, control and maintain; that is overload-proof and self-adjusting without regulation; that can handle highly aggressive and/or solids-laden media without damage (even in hazardous areas); that can suck in medium when it is dry and also run dry; and that is also comparatively cheap to purchase and maintain; then an AODD pump is the perfect choice for you.

ABB is also providing engineering and project management.“The digital aspect is critical to this project due to its remote location—the nearest town being Diego de Almagro, over 100 miles away, the altitude of the project, and adverse weather conditions that make site access and fieldwork difficult especially during the winter,” says Max Combes, project director of Gold Fields. “Gold Fields has developed digital infrastructure through initiatives at operations around the world. ABB’s complete solution, integrated engineering, and remote operations technology will enable us to build on this digital capability and overcome the particular challenges at Salares Norte.”TRAINING AND OPERATIONS SUPPORTThe scope also includes a dynamic process simulator to allow checks on all control logics and for operator training purposes.“The simulator will allow for shorter and more efficient start-ups on site,” says Iván Villegas, solutions manager at ABB in Chile. “It will also support the training requirements, meaning Gold Fields will have several accredited operators with the right skills for high-quality operations.”“Together with Gold Fields we can demonstrate over the long-term that ABB's control systems connect and perform their functions in totally isolated areas, within satellite range, and with minimal latency,” says Cristian Gallegos, mining account manager for ABB in Chile. “It is an opportunity to modernize mining and showcase the benefits that digital transformation brings by controlling and supporting the mining plant and equipment at Salares Norte from over 800 miles away.”SATELLITE TELEMATICS TEST In parallel to this project ABB proposed and was part of an initiative together with Gold Fields to successfully connect different ABB technologies between Santiago and the Salares Norte project. Using satellite telematics they carried out remote control and monitoring of smart electric motors and a simulation of telemedicine care between the two locations. The tests were carried out in isolated areas, but within reach of the satellite and through a connection controlled by ABB Ability System 800xA and conventional mobile equipment with minimal latency. Through mixed reality lenses, both virtual reality and augmented reality, two authorities of the Ministry of Mining in Chile (the minister and the regional secretary) each at one end, were witnesses and protagonists of the successful test, where the two held a conversation that flowed in real time, each "seeing" the avatar of the other, as if they were together in a physical environment. Salares Norte is expected to produce 3.7 million ounces of gold over an initial mine life of eleven years and is estimated to be a $834 million expenditure project. The operation involves drilling, blasting, loading, and hauling methods for ore extraction. It has a production capacity of two million tons per annum and the life-of-mine average recovery of gold and silver will be 92.7 percent and 67.5 percent, respectively.

30 | NOVEMBER 2021WWW.MPTMAG.COMMPTMOTOR SOLUTIONSMOTOR SOLUTIONSMedium voltage variable frequency drives (VFDs) are often the best choice to capitalize on opportunities to significantly reduce the operating and maintenance costs associated with relatively large rotating equipment. And because even a seemingly modest energy savings of a few percent of the operating load can translate into significant energy savings, there are many potential applications for medium voltage VFDs. Medium voltage VFDs are applied to relatively large motors that can range in size from 200 to 100,000 horsepower. Such medium voltage motors typically operate between 10 and 15,000 rpm, at voltages between 2.3 and 13.8 kilovolts. Locating potential medium voltage VFD applications is relatively straightforward because every medium voltage motor should be considered a potential application—if only because of the significant energy savings associated with large motors.Medium voltage drives are used for new installations or retrofit installations. In a new installation, the saved cost of not having to install alternative solutions such as dampers, valves, and mechanical transmissions can be applied to purchasing the medium voltage VFD. In some new applications, the installed cost of a medium voltage VFD can be less expensive than utilizing alternative solutions—especially when the alternative solution is expensive and requires additional plant modifications. In these applications, medium voltage VFDs not only reduce the overall cost of installation but also provide the additional benefit of reducing the total cost of operation. In retrofit applications, the full costs of purchasing and installing the medium voltage VFD—plus the cost of removing or disabling the existing alternative device—makes justification more challenging. Nonetheless, there are still many viable retrofit applications, especially when averted maintenance, repair and replacement costs for mechanical systems can be applied to purchasing the medium voltage VFD—along with much lower energy consumption. In many cases, the VFD will provide a payback in less than two years due to these energy savings; this does not include the reduced cost of ownership when compare to some mechanical systems.For both new and retrofit applications, the utility serving the plant will often offer financial incentives for installing a VFD, which can greatly reduce costs as well as payback time.Motors in which the hydraulic energy or mechanical energy generated by the motor is throttled are prime applications for medium TO SUCCEED, CONTROL YOUR SPEEDUsing medium voltage VFDs to eliminate waste and promote efciency, reliability, and quality Part 1 of 2 BY MARK HARSHMAN, SIEMENS

NOVEMBER 2021 | 31WWW.MPTMAG.COMMPTvoltage VFDs because matching the motor speed to the load conserves the electrical energy associated with generating the throttled energy. For example, it is not uncommon to throttle equipment down to as low as 70 percent of its full load capacity. By matching the motor speed to the reduced capacity of 70 percent, a 50 percent reduction of energy costs is achieved. The affinity laws allow for significant energy savings for even minor reductions in speed, which are realized and saved by using a VFD.BIG MOTORS, BIGGER SAVINGSA VFD is an electronic device that electronically alters the frequency and/or voltage fed to a motor to change its speed, and consequently the speed of the attached equipment. Most plant engineers are comfortable with low voltage VFDs and may use them extensively in their processes to control motor (and equipment) speed where necessary or desirable to improve product quality, increase productivity and/or reduce maintenance. Creative plant engineers are constantly finding new VFD applications in their plants. Medium voltage VFDs accommodate larger motors than their low-voltage equivalents, operating at higher voltages to drive larger equipment. Their applications are often similar in nature to low voltage VFDs—just with bigger sizes and higher voltages and costs. Importantly, the energy savings associated with medium voltage VFDs are typically much higher than for low voltage VFDs because medium-voltage motors use much more electrical power. For example, the savings associated with a 40 percent energy use reduction in a motor consuming 50 kilowatts is 20 kilowatts. The savings associated with a 20 percent energy use reduction in a motor consuming 1,000 kilowatts is 200 kilowatts—10 times more energy savings. This illustrates how the energy savings associated with one medium voltage motor can dwarf the energy savings associated with many smaller low-voltage motors.To put these savings in numerical terms, if power is purchased from the utility at $0.10 per kilowatt-hour and if the motor operates for 8,000 hours per year, the annual energy savings is approximately $800 per year per kilowatt. In the above example, applying a VFD to this medium-voltage motor will reduce electrical energy costs by approximately $160,000 per year. However, many plant engineers are not aware that medium voltage VFDs are available at reasonable costs, relative to their potential energy savings. They may also not know that they have been using throttle control for their large mechanical equipment in industrial plants and other facilities for decades—often for months or years without being shut down—and sometimes in applications that require precise speed control. Further, they are often not aware of the magnitude of the potential energy savings associated with medium voltage VFD applications.Table 1 lists some industries where medium voltage VFDs are commonly applied, along with their typical applications. Naturally, plants with more medium voltage motors tend to have more potential medium voltage VFD applications. However, having only a few medium voltage motors should not discourage consideration; LEADING MEDIUM VOLTAGE VFD APPLICATIONS IN MAJOR VERTICAL INDUSTRIESBuilding automationCooling tower pumps, cooling tower fans, chiller fans, chilled water pumps, refrigeration compressorsCementConveyors, kiln drives and fansChemical and petrochemicalUtility pumps, process pumps, fans, blowers, air compressors, process compressors, coolers, cooling tower pumps, cooling tower fansFood and beverageUtility pumps, fans, blowersMarineLong cable, offloading pumps, topside compressorMiningConveyors, ball mills, grinders, crushers, mobile equipment (haul trucks, draglines, shovels)Oil and gasUtility pumps, process pumps, fans, process compressors, air compressorsPowerInduced draft fans, forced draft fans, cooling tower pumps, cooling tower fans, atomization air compressorsPulp and paperChippers, conveyors, debarking, fans, paper machine line shafts, pumps, refiners, shreddersWater / wastewaterProcess pumps, fans, blowers, air compressors Table 1

32 | NOVEMBER 2021WWW.MPTMAG.COMMPTMOTOR SOLUTIONSMOTOR SOLUTIONSthe application of just one or two medium voltage VFDs—even in plants dominated by low-voltage motors — can have important economic implications. In the cement industry, for example, a single plant typically has almost thirty medium voltage drives, ranging in power from 500 to 2,000 horsepower in pump, kiln and fan application. In some plants, even as few as one or two medium voltage VFD applications can reduce overall electrical energy consumption significantly more than dozens of low voltage VFD applications. Therefore, the large economic impact of applying medium voltage VFDs in these plants typically results in considering the largest motors first, as this is where savings are greatest.MEDIUM VOLTAGE VFDS VS. ALTERNATIVE SOLUTIONSIn many applications, medium voltage VFDs are superior to alternative solutions for controlling motor speed such as direct current drives, soft-starters, two- and three-speed motors, and single-speed motors coupled to various transmission components. In other applications, medium voltage VFDs can replace mechanically based solutions used to control process parameters, such as the flow of a gas or liquid. For example, the flow of air into a large furnace or boiler can be regulated using a single-speed motor and air vanes. However, controlling the mechanical equipment by using a medium voltage VFD to vary motor speed usually results in a superior process control, increased reliability and improved operational costs. In either case, medium voltage VFDs offer many advantages over alternative solutions. Some of the advantages are listed in Table 2. Note that these advantages apply to specific applications in varying degrees. This will become evident when the advantages and expected results from various medium voltage VFD applications are discussed below. Medium Voltage VFDs vs. Direct Current DrivesDirect current (DC) drives vary motor speed by fluctuating the direct current voltage to the motor. VFDs, however, vary motor speed by fluctuating the frequency to the motor. Some of their advantages are similar because both control motor speed electronically. DC motors are not as common and are typically more expensive than the corresponding alternating current (AC) motors used with VFDs. DC motors also have internal brushes that require periodic maintenance, thus compromising reliability.As a result, the industry trend has been towards the application of AC motors. The large population of AC motors and numerous variable speed applications has tended to reduce the cost of VFDs as compared to DC drives.DC drives have historically been used for applications that require precise speed and torque control, but due to improved AC VFD technology and declining costs, few applications still require DC drives and motors with their higher upfront and maintenance costs.Medium Voltage VFDs vs. Soft-startersMotors generally exhibit high inrush currents when started. The current falls to normal levels after the motor reaches full speed a few seconds later. Inrush currents can play havoc with plant electrical distribution systems, and can also result in very high demand charges from the electric utility. Demand charges are typically assessed based on the greatest instantaneous power usage—a figure that can be quite high if a large motor is started at full speed.One method of reducing the magnitude of inrush currents and the resultant stress on the motor is to use a soft-starter that electrically reduces voltage to the motor for a few seconds before switching to line voltage. Soft-starters cannot ADVANTAGES OF MEDIUM VOLTAGE VFDS OVER ALTERNATIVE SOLUTIONS1. Decreased electrical energy consumption2. Lower electrical demand charges from utilities3.

NOVEMBER 2021 | 33WWW.MPTMAG.COMMPTvary motor speed, so they are not an alternative to a VFD in most applications. VFDs are inherently soft-starters because VFDs ramp the voltage to the motor and limit inrush currents. In this regard, VFDs provide even softer starts than traditional soft-starters. VFDs can almost always start a motor and will draw significantly less starting current (usually less than 100 percent rated FLA) than soft-starters that still draw up to 300 percent inrush current. VFDs are not recommended in applications where precisely controlling motor speed does not provide economic or operational benefit. In these applications, soft-starters may be required to address electrical problems associated with high inrush current, and will be a more economical solution than a VFD.Medium Voltage VFDs vs. Two-speed MotorsStarters that electrically alter the motor winding connections can allow the same motor to operate at two speeds—typically full speed and 50 percent speed. Operation at the reduced speed when the motor is lightly loaded can reduce the electrical energy consumption of the motor. This can represent significant energy savings under low load conditions. However, when the process load increases, the motor will be switched to full-speed operation and consume much more energy. In contrast, VFDs can vary the motor speed continuously from zero to full speed, allowing the motor to operate at the precise speed needed to match the load and process requirements. The VFD strategy of matching the speed to the load is much more energy efficient, resulting in significant savings.To illustrate, consider this VFD application: A medium voltage motor connected to a centrifugal fan consumes 600 kilowatts of electrical energy while operating at 60 percent speed using a VFD. In contrast, a two-speed motor would have to operate at full speed because 50 percent speed will not satisfy the load. Increasing the motor speed in this manner will increase energy consumption to 1,000 kilowatt at full speed. If power is purchased from the utility at $0.10 per kilowatt-hour and if the motor operates for 8,000 hours per year, the annual energy savings saved is approximately $800 per year per kilowatt. If this motor can be operated at 60 percent speed, applying a VFD to this motor will reduce electrical energy consumption by approximately 400 kilowatts—or $320,000 per year.A LOOK AHEADIn next month’s wrap-up, we’ll further explore how medium voltage VFDs stack up, specifically against mechanical devices, mechanical transmission methods, and mechanical throttling devices. Plus, depending on the particular application, medium voltage VFD installations can exhibit other benefits that may be difficult to quantify. All of this bolsters how medium voltage VFDs are typically superior to alternative technologies. MARK HARSHMAN is principal engineer at Siemens.

34 | NOVEMBER 2021WWW.MPTMAG.COMMPTSEALING SOLUTIONSSEALING SOLUTIONSTHE MECHANICAL SEAL INDUSTRY’S CONTRIBUTION TO ENERGY EFFICIENCY IN PUMPING SYSTEMS Part 2 of 2 BY RICHARD SMITH AND CHRIS BOOTH, AESSEAL www.mptmag.comSee Part 1In last month’s beginning to this article, we posited that, although sealing devices account for only a small fraction of the energy consumed by pumps, significant energy conservation can be achieved by elegant sealing practices. In the conclusion that follows, we’ll more closely examine the ways energy content can be made lower in a modern context with mechanical seals by looking into real-world examples and case studies.EVAPORATOR PUMPS CASE STUDY: CONVERSION FROM PLAN 32 TO PLAN 53 In this example, energy efficiency was improved by converting from a single mechanical seal with external flush (Plan 32) to a double seal with barrier system (Plan 53A). The application was at a scotch whiskey distillery where pot ale, a byproduct, is processed in a syrup evaporator to make animal feed. Efficiency Loss Under API Plan 32 There are three evaporator circulation pumps, which were fitted with single mechanical seals and a simple Plan 32 flush (see figure 8). Clean fluid from an external source is used to flush the seal chamber, to exclude solids or contaminants, and to reduce the temperature at the seal. It is also used to reduce flashing or air intrusion (in vacuum services) across the seal faces. The main driver for the use of this system is its low initial cost. A survey of the evaporator system revealed the inefficiency of this flush plan. Syrup was being fed to the evaporator at the rate of 40 gallons per minute, but also being diluted by 0.5 gallons per minute, per pump, of clean flush fluid. The additional 1.5 gallons per minute of liquid into the process meant having to evaporate at least 4 percent more liquid. An analogy is having to walk 26 miles to actually only cover 25. In addition, the injected flush water came from a mountain stream source at 41 degrees Fahrenheit (5 degrees Celsius), so more heat was being added to the process to maintain evaporation temperature. Heating the cold flush water to the evaporation temperature requires 19 kilowatts, or 460 kilowatt-hours per day. Evaporating the flush water requires over 200 kilowatts or 4,800 kilowatt-hours per day.Conversion Efficiency Improvement Under API Plan 53A Conversion to a double seal system with Plan 53A (see figure 9) eliminated the need for seal flush. A small API Plan 32Figure 8: Flush is injected into the seal chamber from an external source.OPTIONALAPI Plan 53AFigure 9: Pressurized external barrier fluid reservoir supplying clean fluid to the seal chamber. Circulation is by an internal pumping ring. Reservoir pressure is greater than the process pressure being sealed.

Page 39

NOVEMBER 2021 | 35WWW.MPTMAG.COMMPTpressurized tank is introduced, containing 2.6 gallons (see figure 11) of barrier fluid. This is circulated either by convection or by a small circulating device built into the seal. The pressurized barrier fluid provides a clean liquid environment for the inner seal faces and prevents air intrusion to the vacuum. With all three pumps converted (see figure 10), syrup production increased from 97 to 108 tons per hour resulting in a significant reduction in plant running hours. In addition, over 5,000 kilowatt-hours per day was liberated for better use elsewhere.Evaporator Plant Installations Any business operating pumps on evaporator systems needs to consider with great care the piping plan used on the pump seals. Plan 32 is often found in many industries, including pulp and paper, sugar production, and chemical process such as nylon manufacturing. WATER QUENCH CASE STUDY: CONVERSION FROM QUENCH TO PLAN 53 A quench is similar to API Plan 62. Water from an external source is passed between two co-axial seals and away to drain. The water quench is used to prevent solids accumulating on the atmospheric side of the mechanical seal, and can considerably improve seal reliability. Quench Usage and Effluent This system (see figure 12) is common in many industries including brewing, distilling, pulp and paper, corn milling, sugar production, dairy processing, and chemical production.Quench flow rates are typically just under a gallon per minute, per seal installation. In addition to the cost of the water used, the cost and energy consumption of effluent treatment should not be overlooked. The main driver for the use of this system is again its low initial cost Thermosyphon Alternate Plan 53A Effluent Elimination An alternative to this system is to use a barrier system (see figure 13), similar to API Plan 53A. Such systems are self-contained, and more importantly they produce no effluent. If the water supply is connected so as to both pressurize and maintain the level in the tank, no manual intervention is required, and maintenance costs are reduced. An air space can serve as an expansion volume, minimizing the effect of temperature changes. In the event of water supply interruption, the air volume and a check valve maintain pressure until supply is resumed. BOILER FEED PUMP CASE STUDY: CONVERSION FROM GLAND PACKING TO MECHANICAL SEALS This case study involves the conversion of a boiler feed pump from a traditional soft packing gland (see figure 14) to a Plan 23 mechanical seal. To help prevent the rubbing friction damaging the packing, the gland follower would be adjusted to allow a small leakage to flow, typically a slow drip rate. The leakage serves to assist in cooling and lubrication of the gland. As the packing and shaft wear, adjustment will be required to control the leakage rate.Figure 11Figure 10Water SupplyEffluent Treatment PlantFigure 12Alternate Technologies WaterManagement Systems Based on Plan 53AElimination of EffluentFigure 13Figure 14

Page 40

36 | NOVEMBER 2021WWW.MPTMAG.COMMPTSEALING SOLUTIONSSEALING SOLUTIONSThe case study in question is for a boiler feed pump at a petrochemical facility in the northeast of the United Kingdom. The pumps were installed in the late 1970s and furnished with packed glands. The pumps are multi-stage units with glands at both drive and non-drive ends. This arrangement is typical of many applications around the world at chemical works and refineries. Most of the feed water pumps installed in this era were fitted with packed glands and many continue to run today using this technology. Leakage from the packed glands will be a pure loss to the operation. In this example the feed water in the pump was at 250 degrees Fahrenheit (121 degrees Celsius). Losses through the packed gland would need to be made up with water from the treatment plant. The calculation of the energy loss is based the energy required to take the make up water from 50 degrees Fahrenheit (10 degrees Celsius) to feed water temperature of 250 degrees Fahrenheit (121 degrees Celsius). In this instance the boiler plant is gas fired and the heat energy requirement can be translated into a net CO2 contribution. Due to a reduction in plant manning, the gland follower adjustment was only made when the leakage was severe. As a result, the average leakage rate from the pumps was about quarter gallon per minute per gland (see figure 15).With eight pumps (sixteen glands) leaking on average a gallon every four minutes per gland energy loss is calculated at 124 kilowatts. The plant operates 24 hours per day, 365 days per year, giving an annual energy loss of 1,086,240 kilowatt-hours. The energy savings are purely based on heating requirements and do not include energy costs for water treatment, de-aeration and any pumping. It is worth noting that the reduction in energy does not reduce the power absorbed by the pump but provides for savings in the combustion process and boiler operation costs. Investigation of the combustion process by site personnel indicated that 4 ounces of CO2 is emitted per gallon of water heated. With losses of a quarter of a gallon per minute per gland (across sixteen glands), there is a calculated saving of 261 tons of CO2 pear year. By comparison the average European high efficiency diesel car covering over 12,000 miles per year would emit 3.5 tons per year; therefore, the saving is equivalent to nearly eighty cars.MINERAL EXTRACTION SLURRY PUMP CASE STUDY: CONVERSION FROM GLAND PACKING TO MECHANICAL SEAL Population growth, economic development, and climate change have led to pressure on the water supply in many parts of the world including the United Kingdom. According to the Organization for Economic Cooperation and Development (OECD), access to reliable and safe water represents one of the greatest challenges facing humanity in the twenty-first century. The use of flush water in pumping applications, sometimes in large quantities, must be questioned. This practice is still widespread around the world. The final case study is the conversion to mechanical seals of a number of large slurry pumps with packed glands. The Debswana operation consists of various diamond mines at Orapa in Botswana, a dry semi-desert area. Essential to the operation are slurry pumps pumping kimberlite and iron silicate. These applications are amongst most abrasive in the slurry-pumping world. Gland Water Requirement The packed glands on the pumps needed flush water injection (Plan 32) into the process media, at a rate of 15 gallons per minute to exclude slurry from the seal chamber. If the water supply failed, damage occurred to the gland within thirty seconds. Only 10 percent of the flush water is recoverable from the process. A typical train of five pumps consumes over 35 million gallons per year of water from underground sources. Figure 15: Severe leak on packed gland pump.Alternate Technologies Double SlurrySeal & Water Circulation System Plan 54Figure 16

Page 41

NOVEMBER 2021 | 37WWW.MPTMAG.COMMPTDue to constant extraction over many years, the water table was dropping and the resource was threatened. An official mandate was tabled to reduce water consumption by 10 percent immediately and 15 percent in the medium term. Pipelines from various alternative sources were considered. The most effective, and most extreme, was to build a 372-mile-long pipeline from the Okovango delta to Orapa at a cost of $30 million. This could have endangered water levels in the delta, a world heritage site. Double Seal Conversion Fitting double seals with water circulation systems (see figure 16) to just eighteen pumps reduced gland water consumption by a significant proportion of the 10 percent total savings required across the site. A further fifty seals and systems have now been installed, covering all the pumps using large volumes of gland service water. Energy Saving The primary motivation for the conversion was to tackle the issue of aquifer depletion; however, the secondary benefit of energy conservation should not be overlooked. The complete original gland water system needs to be considered. The system illustrated at Damtshaa mine (part of the Debswana operation) is typical of many of the mines in Orapa (see figure 17). Energy saving are made because bore hole pumps are no longer required to lift the volume of gland water to a storage reservoir on the surface. Typically, a bore hole is drilled to over 800 feet with the water table at approximately just under 600 feet. Bore hole pumps are of the helical rotor type and being belt driven are approximately 75 percent efficient. From the reservoir, a multistage pump increases pressure injecting the gland water into the pump casing. The calculated energy consumption of this system is 394,084 kilowatt-hours per year. African power generation is highly dependent on coal. For every kilowatt saving, there is an equivalent atmospheric saving of over 2 pounds of CO2. The double seal conversion utilized a simple tank recirculation system, with total energy consumption of less than 30,000 kilowatt-hours per year. Hence, energy savings of over 350,000 kilowatt-hours per year were achieved.CONCLUSIONSConsideration of pump seal auxiliary piping systems needs to be given greater priority. The energy indirectly consumed is often ignored, with minimum capital cost being the prime driver when plants are designed. In addition, mature pump installations fitted with traditional high maintenance packing arrangements should be reviewed in terms of plant efficiency. The mechanical seal industry has developed efficient, elegant solutions that provide the operator with higher reliability, lower life-cycle costs, and reduced environmental impact.

Problems with motor bearing damage creates frustrating and expensive downtime. That’s why millions of motors around the world depend on AEGIS® Rings to keep bearings safe from unpredictable currents that result in motor failure. Electro Static Technology’s patented design provides the most reliable current diversion technology for extending motor life. Learn more at www.est-aegis.com.Reduce Your Pump Energy UsePumps and pumping systems account for 25% of the energy consumed by electric motors in the United States. In pumping intensive industries, this number is over 50%.To improve the efficiency of pumping systems and reduce their energy consumption, pump users are turning to variable frequency drives (VFDs). Since most pumping systems are designed for maximum service conditions, running them at partial load can save considerable energy. So, by precisely matching motor speed to pumping requirements, VFDs can reduce energy costs by as much as 30% or more.But VFDs Can Damage Pump Motor Bearings VFD-induced voltages on motor shafts can discharge through motor bearings, causing pitting, frosting, ﬂuting, and total bearing failure in as little as 3 months! Pumping System Reliability is CriticalPump motor failures can cost hundreds of thousands of dollars in repairs and in this industry, the unplanned downtime from motor failure is even more expensive. To ensure the reliability of VFD-driven pump motors and systems, bearing protection is needed.Proven Long-Term Bearing Protection By providing a very-low-impedance path from motor shaft to ground, AEGIS® Shaft Grounding Rings ensure the reliable, long-term operation of VFD-driven pumping systems. Proven in millions of installations worldwide, AEGIS® Rings provide unmatched bearing protection of the full L10 life of the motor bearings.31 Winterbrook Road Mechanic Falls, ME 04256Phone: +1 207-998-5140 Toll Free (U.S.): 1-866-738-1857 ISO 9001:2015 Certiﬁed40 | NOVEMBER 2021WWW.MPTMAG.COMMPTCOMPANY PROFILESCOMPANY PROFILES

42 | NOVEMBER 2021WWW.MPTMAG.COMMPTCOMPANY PROFILESCOMPANY PROFILESGas Clip Technologies Gas Clip Technologies believes that quality and affordability go hand-in-hand, which is why they manufacture top-of-the-line gas detectors and accessories that meet every budget. Each product meets the highest standard of reliability and battery life to ensure that every user’s safety remains uncompromised. Gas Clip’s multi gas detectors are perfect examples.MULTI GAS DETECTORSThe Multi Gas Clip was Gas Clip’s first multi gas detector, and it was also the first portable gas detector in the industry to utilize infrared technology to detect combustible gases (LEL). The continuous run time of the Multi Gas Clip is two months. However, its sisters—the MGC Simple and the MGC Simple Plus—have continuous run times of two years and three years respectively. Additionally, after being charged and calibrated during manufacturing, neither the MGC Simple nor the MGC Simple Plus require recharging or routine calibration, although bump testing prior to every use is advised. Also, all three of these detectors are designed to identify the presence and level of hydrogen sulfide (H2S), carbon monoxide (CO), oxygen (O2), and combustible gases (LEL).SINGLE GAS DETECTORSIn turn, on the days that require a single gas detector, Gas Clip Technologies have two to choose from—the Single Gas Clip (SGC) and the Single Gas Clip (SGC) Plus. Both include superior sensor reliability along with adjustable alarm set points, a programmable six-digit detector ID code, and a two-year battery life. However, the SGC Plus also includes a built in “hibernate” mode that allows users to place it in a rested state when not in use. It is available in two models—SGC Plus H2S for detecting hydrogen sulfide and SGC Plus CO for detecting carbon monoxide. The Single Gas Clip, on the other hand, comes in three different versions—SGC O2 for testing oxygen levels, SGC H2S for testing hydrogen sulfide levels, and SGC CO for testing carbon monoxide levels.GAS CLIP’S NEWEST ADDITION: THE GCT EXTERNAL PUMPAs for accessories, Gas Clip Technologies released the new GCT External Pump earlier this year. It is a motorized sampling pump that allows any Gas Clip diffusion detector—single gas and multi gas—to take remote samples from up to 75 feet away. It has a forty-hour continuous run time on average, and the battery typically recharges in four to six hours. Audio and visual alerts will inform the user of possible errors including blockages and a low battery charge. Additionally, the sleek, ergonomic design of the pump allows it to sit comfortably in the user’s hand, which helps prevent potential drops. However, an alligator clip allows the user to firmly attach the pump to their belt, jumpsuit, etc. as needed. Either way, if the device takes a tumble, the durable casing can withstand the fall as well as other harsh treatment.CLOSING THOUGHTAfter more than a decade of creating industry-changing products, including their new GCT External Pump, Gas Clip Technologies continues to keep their focus on the future and how to further develop simpler and safer gas detection solutions. However, those two concepts are merely stepping-stones to their ultimate goal—helping workers get home to their families at the end of the day; and in truth, that is what gas detection is all about.

60 | NOVEMBER 2021WWW.MPTMAG.COMMPTCOMPANY PROFILESCOMPANY PROFILESVaughan Company Vaughan Company was started with one simple question, “What could make this better?” In the service bay of the gas station he owned in Elma, Washington, Jim Vaughan spent hours repairing manure pumps for local dairy farmers. He could see a pattern: the pumps were constantly breaking down due to clogs caused by animal bedding or twine. So in 1960, Jim Vaughan invented the world’s first chopper pump. The Chopper Pump met a genuine need that had applications far beyond dairy farms. The original patent for the Chopper Pump was applied for in 1960 and granted shortly thereafter. By 1961, the company purchased its own manufacturing facility in Montesano, Washington. In the decades since, Vaughan Company has expanded operations greatly and now has forty worldwide patents.Now a third- and fourth-generation family-owned-and-operated company, Vaughan Company manufactures pumping and mixing equipment for agriculture, municipal, and a variety of industrial applications, shipping worldwide. From 1960 to today, our goal is to produce reliable products that perform in the most demanding applications. And as the years have passed, we’ve implemented new technologies to stay innovative.We incorporate in-house 3D modeling, which allows us to create precision castings for all components. With computational fluid dynamics (CFD), we analyze flow patterns and velocities within our pumps, looking for ways to maximize performance. And our computer numerically controlled (CNC) automated machining ensures every Vaughan replacement part fits precisely.With more than half a century of experience, Vaughan Company remains committed to giving customers outstanding service and the most dependable product solutions in the world.VAUGHAN CHOPPER PUMPThe Vaughan Chopper Pump is a centrifugal pump with the unique ability of chopping all incoming solids prior to pumping. This not only protects the pump from clogging, but also provides added benefit to downstream components, processes, and the environment.All wear components are cast steel and heat treated for maximum impact and wear resistance. These heavy-duty patented components create the ultimate pump for handling severe solids.VAUGHAN ROTAMIX® SYSTEMThe Vaughan Rotamix® System is the world's most reliable cost-effective means of mechanical hydraulic mixing for sludge tanks, digesters, and other high-volume applications.Combining high-velocity mixing nozzles and the Vaughan Chopper Pump, Rotamix® creates a multi-zone mixing pattern while simultaneously chopping all accumulated solids. No more floating mats or solids settled at the bottom of your tank. The Vaughan Rotamix® System produces an easy-to-pump, homogenous mix.The solutions Vaughan Company offers start here.

64 | NOVEMBER 2021WWW.MPTMAG.COMMPTCOMPANY PROFILESCOMPANY PROFILESHorner Industrial Group The Horner Industrial Group, founded in 1949 as Horner Electric, began as an electric motor repair company. Throughout the years they’ve expanded their repair capabilities to include gearboxes, fans, blowers, pumps, and hydraulic cylinders. In 2013, they created the Horner Thermal Spray and Industrial Coatings division. In 2019, they combined their Pump Repair division with their Thermal Spray and Industrial Coatings division to create a unique offering to their customer base. By applying the latest spray and coating technology associated with reducing wear and extending life to pump repair, the resulting end product is far superior to any standard pump repair currently in the marketplace. The Twin-Arc Thermal Spray method used by Horner Industrial has been used by the military, (predominately Navy and Air Force), for over thirty years and can be used to apply ANY metal on ANY metal without galvanic reaction taking place with a holding force exceeding 9,000 psi, and it never heats up the base material more than 300 degrees Fahrenheit (148 degrees Celsius) unlike welding or other spray metal finishes on the market. The only way to remove the coating is to machine or grind it off. They then use a Loctite coating made for pumps that increases the abrasion resistance of the finished product, resulting in prolonged performance with less maintenance issues and higher efficiencies held for longer period of times. It is now possible to completely restore an obsolete damaged impeller, shaft, rotating element, or pump case and restore it back to “like new” condition at a fraction of the price of a new unit in a fraction of the time it would take to get a new, replacement part.

NOVEMBER 2021 | 65WWW.MPTMAG.COMMPT2022 | BUYERS GUIDEKROHNEKROHNE offers a complete measurement instrumentation product portfolio including industry specific system solutions and complementary services for projects of any size, anywhere in the world. Since starting in 1921, we have amassed an enormous amount of application knowledge that is integrated into our products, solutions, and services. The resulting innovative technologies are based on our extensive R&D with 10 percent of the work force dedicated that area. While sensor development for flow, level and other variables is the primary focus, we are also very active in advancing device communication and the Internet of Things (IoT) for the process industries including device diagnostics for analysis and process optimization.If you buy a KROHNE product, you will get a measuring device that performs most accurate with low uncertainty under real process conditions. To achieve this, we operate more than 120 calibration facilities for volume flow, mass flow, level, temperature, density, and pressure for every device we manufacture. For example, every flowmeter is wet calibrated using water or air as standard before leaving our facilities. We can also provide customer specific calibration such as: • Multipoint calibrations• Varying temperatures, viscosities, or pressures• Specific fluids• Specific pipe geometries or piping provided by the customerFor calibration we only use direct comparison. For example, we calibrate our Coriolis mass flowmeters with a gravimetric weighing system. Our calibration rigs are the most accurate for measuring device production with reference accuracies 5 to10 times better than that of the meter under test.This goes for small (1 millimeter) or very large meter sizes since Krohne operates precise volumetric calibration rigs up to 120 inches with a certified accuracy of 0.013 percent based on a 144-foot-tall tank containing almost 132,000 gallons of water allowing for a maximum flow rate of 7,925,000 gallons per hour.In North America, we have a brand-new manufacturing and calibration facility in Beverly, Massachusetts.
