Appomattox started production in May 2019—four months ahead of schedule—and its forty-year design life provides modern and efficient infrastructure for the safe and sustainable delivery of energy to the United States. Appomattox is the result of hundreds of companies that came together to align on common goals related to safety, care for people, cost, and schedule. In addition to maximizing production, Appomattox developed new technology to minimize its environmental footprint. A combined cycle power generation system reduced greenhouse gas emissions by 30 percent and the use of cold seawater below the surface shrunk the cooling system by 40 percent compared to established designs. These technologies made it possible for the project to avoid impact to marine life in the shallower, warmer waters of the Gulf of Mexico.OTC HERITAGE AWARD: The annual Heritage Award will be presented to Roland Moreau for his leadership in advocating for the gathering and analyzing of safety data and sharing learnings from operations in the Gulf of Mexico to improve industry safety. Moreau’s nearly four decades of experience, extensive network,and effective recruiting skills have also contributed to enhancing the communications and bridging the knowledge gap between the offshore oil industry and government bodies such as the U.S. Department of the Interior’s Bureau of Safety and Environmental Enforcement (BSEE) and the U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS) regarding their health, safety, and environmental (HSE) offshore programs.ENERGY4ME TEACHER STEM WORKSHOP One of the most popular components of OTC, this year’s Energy4me Teachers STEM Workshop will have an emphasis on activities around reducing emissions in the industry. At this free, one-day workshop, science teachers receive hands-on training by qualified facilitators, listen to a presentation from a prominent energy professional, and tour the OTC exhibit floor. Additionally, teachers receive a variety of free instructional materials to take back to their classrooms. As the United States and global community work toward developing technologies and methods to mitigate the release of carbon dioxide, it is important to understand the processes and technologies in place to do so. Carbon capture, utilization, and storage (CCUS) is one advanced method for mitigating the release of carbon dioxide into the atmosphere from fossil-fueled power stations. These activities will help teachers and their students understand why CCUS is part of the solution and how it will impact energy supply, demand, and cost. In the workshop, attendees will hear from industry speakers about reducing emissions and the energy transition. OTC’s Energy4me Teachers STEM Workshop provides educators and industry an opportunity to connect they would not find any other place.

14 | APRIL 2022WWW.MPTMAG.COMMPTCASE STUDIESCASE STUDIESThe city of Hot Springs, Arkansas, wastewater treatment system serves 23,000 customers and requires the maintenance of more than 600 miles of gravity sewers and force mains. With the goal of implementing a more proactive maintenance program that would also address issues arising from capacity constraints and aging equipment, the city undertook a comprehensive overhaul of its municipal wastewater infrastructure. As part of the program, Bobby Harris, the city’s utility field operations manager, prioritized the system’s seventy-six lift stations. Several of these stations had been identified as part of a consent administrative order (CAO) between the city and the Arkansas Department of Environmental Quality (ADEQ) in an effort to bring the wastewater system into compliance.THE CHALLENGEThe infrastructure upgrades kicked off in 2013 with the Fairwood Lift Station, which serves as the main collection station for the west side of the city. The lift station, with a peak capacity of 5.8 million gallons per day, experienced frequent overflows. The city identified equipment failure/malfunction and loss of power at the pump station as the primary causes for overflows. The station experienced sewer overflows during heavy rainfall events or when the pumps clogged because of increasingly popular “disposable” products—such as cleaning cloths and disinfecting wipes—which can build up on the leading edge of pump impellers and become tangled. This build-up reduces the efficiency of the pumps or even causes a complete stoppage.The revamped lift station was equipped with Xylem Flygt Model NP 3231/765 “N” pumps. The 335-horsepower submersible pumps are operated via variable speed drives and are designed to deliver 4,050 gallons per minute each. The technology incorporates patented clog-resistant impellers, unlike the station’s previous pumps. Realizing that additional steps were needed to properly address long-term prevention of future sanitary sewer overflows, the city of Hot Springs investigated a permanent backup system. They wanted a system that would provide pumping not only during power outages but also during mechanical failures. A system that could also provide additional capacity would be even better. A typical would be to install a diesel-powered backup generator. This solution, however, would not help Hot Springs if the station’s pumps or generator’s switchgear failed—and wouldn’t allow for additional flow capacity brought on by severe rains. The utility also wanted greater flexibility when the submersible pumps were taken offline for any reason.THE SOLUTIONInstead of a backup generator, the Xylem team recommended a PUMP STATIONS THAT WILL NOT FAILArkansas utility takes redundancy a step further with a permanent backup system BY MOLLY RUSSELL, XYLEMPROJECT SPOTLIGHTCUSTOMER:Hot Springs, Arkansas CHALLENGE: The city of Hot Springs sought lift station redundancy within its municipal wastewater infrastructure. XYLEM SOLUTION: The two-story building was designed to withstand the impact of a Category 3 hurricane. The design will allow Sarasota Memorial Hospital and other critical designated storm shelters to remain operational after a storm. City officials directed the project engineer, McKim & Creed, to bring critical equipment above ground to a height above Category 3 storm surge elevation. The Fairwood Pump Station is one of six pump stations to be equipped with Godwin Dri-Prime Backup pump units.

The primary benefit of redundant design is prevention of a total system failure. Harris, together with design engineer Jerry Williams, PE, principal of local engineering consultant Engineers, Inc., chose the Godwin Dri-Prime Backup pump unit as a backup for the Fairwood Station.The benefits of utilizing the natural gas-powered pumping unit in lieu of a diesel-powered electrical generator was introduced to Harris and Williams by Sherman Eoff, president of Jack Tyler Engineering, Inc., the local Xylem representative. Natural gas-powered pumps provide independent and resilient pumping during events when the permanent infrastructure is compromised. Natural gas also provides a continuous uninterrupted The Godwin PrimeGuard controller provides greater visibility and peace of mind by connecting with a SCADA system, registering when the backup pump is running.Xylem Flygt Model NP 3231/765 “N” pumps deliver over 4,000 gallons per minute.

16 | APRIL 2022WWW.MPTMAG.COMMPTCASE STUDIESCASE STUDIESfuel supply, whereas a diesel-powered generator would require a large on-site storage tank or regular fuel delivery. After Harris and Williams researched and compared other offerings, the decision was made to utilize a Godwin DBS station backup instead of just an electrical backup.Powered by a 425-horsepower natural gas engine, the HL250M DBS pump operates on an above-ground foundation adjacent to the wet well. The heavy-duty pump is well-suited for the backup mission because of its self-priming feature and ability to handle the high discharge pressure and high suction lift conditions at the Fairwood station.The backup pump is also equipped with a Godwin PrimeGuard controller to provide greater visibility and peace of mind. The controller sends signals to the city’s SCADA system, notifying department personnel when the backup pump is running, so they can initiate a visit to the lift station if needed. Another great benefit to the city is the system’s ability to only activate the backup pump when needed, therefore saving fuel and limiting operating hours.When a lift station is equipped with a generator, it runs constantly the whole time the power is out, whether the pump station is requiring standby power or not.THE RESULTBesides delivering 100 percent redundancy, the Godwin DBS provides convenience. Whenever the primary pumps in the lift station requires repair or maintenance, crews can manually start the permanent backup pump, which is much easier than bringing in one of the department’s portable pumps for a temporary hookup.In all, six pump stations have been equipped with a backup pumping system using natural gas as part of the ADEQ-mandated, $70 million overhaul of the wastewater system, including the Stokes Creek pump station in 2015 and the Hot Springs I, II, III, and IV pump stations in 2017. The DBS unit at the Stokes Creek station took over operation while the pumps inside the station were down for maintenance. Most importantly, there have been no overflows since the utility installed the DBS units. Even in the most extreme peak-flow weather events, the Godwin DBS is more than adequate to provide protection and coverage, providing additional capacity to handle wet weather flows and pressures when the submersible pumps cannot keep up. As Hot Springs continues to map out its maintenance and upgrade activity, there are plans to retrofit additional lift stations with backup pumping systems. Another great benet to the city is the system’s ability to only activate the backup pump when needed, therefore saving fuel and limiting operating hours.Xylem is a leading global water technology company committed to solving critical water and infrastructure challenges with innovation. Xylem’s more than 16,000 diverse employees delivered revenue of $4.88 billion in 2020. Xylem is creating a more sustainable world by enabling its customers to optimize water and resource management, and helping communities in more than 150 countries become water-secure.

18 | APRIL 2022WWW.MPTMAG.COMMPTCASE STUDIESCASE STUDIESAt an organic dairy farm in Lancashire, where the ethos is firmly on maximizing efficiency over maximizing output, a Landia chopper pump is playing a vital role in the use of slurry as fertilizer.Using energy captured from solar panels at the all-electric, 247-acre farm, the 7.5 kW pump transfers slurry nearly a third of a mile, directly from the main dry cow house to the external lagoon, making considerable savings on fuel and labor. HIGH QUALITY WITHOUT THE HIGH COSTA supplier to the Arla dairy co-operative, which has one of the world’s largest externally-validated climate data sets from dairy farms, Old Holly Farm near Garstang is run almost entirely by one person: Ian Pye.“First, we tried a diesel pump,” says Pye, “but the process was costly and took up way too much time. Every drop of slurry is important to us, so we wanted a simple and long-lasting solution, which to be honest, we believed we could achieve with Landia, but given their pedigree, thought would be too expensive. “However, this just wasn’t the case at all with cost,” Pye continues, “and five years on, the decision has been more than justified; very good value for money, actually. It just works; WHEN EVERY DROP MATTERS, CHOOSING THE BEST IS A NO BRAINERSlurry pump helps with efciency at resourceful organic dairy farm BY SOREN RASMUSSEN, LANDIA, INC.Ian Pye at Old Hollly Farm.

Compared to scooping up slurry with a tractor and then transporting it, sending it directly to the lagoon with a decent pump is a no brainer”.TACKLING A TOUGH, THICK TASKWhen manure from the farm’s 140 cows is particularly thick (depending on time of year/diet/maternity), it is moved over 300 feet to the lagoon in the yard, but the vast majority of time, the Landia Chopper Pump—which for flexibility, was supplied with a moveable control panel—sends the slurry straight to the lagoon. Continually breaking down solid particles, the pump’s knife system prevents harmful debris from entering the pump’s casing, so that it remains clog-free.Pye adds, “In five years, all we’ve ever needed for the pump has been a new float switch, which is very good going. Even then, it was all very simple and economical; quick turnaround, with a part that our electrician could fit easily.” MORE THAN A CLIENT, A FAMILYPye notes that Landia’s commitment to service after the sale was another winning component in his choice of pumps. “Some companies can make the supply of spares unnecessarily difficult and very costly, but we’ve had nothing but friendly and helpful support from Landia,” Pye adds. “From day one, they listened hard to understand what we wanted to do, and how they could help us best achieve our goals.” SOREN RASMUSSEN is the director of Landia, Inc. Landia uses its nearly ninety years of experience to continue to develop new and efficient products and solutions. Together with its customers, Landia is aiming for new heights.

20 | APRIL 2022WWW.MPTMAG.COMMPTWATER & WASTEWATER FOCUSWATER & WASTEWATER FOCUSFor industrial process facilities, membrane filtration is a valuable, commonly used means of filtering water and wastewater. The challenge is that membrane systems are delicate and can be easily damaged by large particulates in the water. A pre-filtration step eliminates this risk by removing oversized suspended solids to prevent damage, eliminate unnecessary maintenance, and reduce the cost of premature membrane replacement.Among the pre-filtering options available, automatic self-cleaning scraper strainers are increasingly popular because they are affordable, require very minimal maintenance or attention, and can remove solids down to 75 microns. The strainers allow for continuous, uninterrupted flows even during blowdown cycles. When compared to filters that must be manually cleaned or even conventional backwash systems, automatic scraper strainers can save substantial costs on maintenance and membrane replacement.INDUSTRIAL WATER TREATMENT AND MEMBRANE SYSTEMSAlthough various filtration methods use membranes, the most mature is pressure driven membrane filtration, which relies on a liquid being forced through a filter membrane with a large surface area. Depending on the size and type of the particles involved, the process could be categorized as reverse osmosis, nanofiltration, ultrafiltration, or microfiltration.In general, reverse osmosis is used to produce potable water or deionized water. Nanofiltration is used in wastewater treatment as well as by the AUTOMATIC SCRAPER STRAINERS PROTECT CRITICAL MEMBRANE SYSTEMSPre-ltering water and wastewater prevents particle damage, reduces maintenance, and lowers replacement costs BY DEL WILLIAMSAutomatic scraper strainers like those from Acme Engineering can provide continuous removal of suspended solids to comprehensively protect membrane systems.

APRIL 2022 | 21WWW.MPTMAG.COMMPTpetrochemical industry to purify gas condensates, and the chemical industry for solvent recovery. Ultrafiltration and microfiltration are increasingly used in water and wastewater treatments. Numerous industries have high water usage that can require further treatment of water, including automotive, aerospace, oil and gas extraction, refining, textiles, and pulp and paper mills. Ultrapure water, which must meet strict limits of certain constituents in the water such as suspended and dissolved solids, dissolved gases, organic carbon, and biological organisms, is utilized in electronics and pharmaceutical manufacturing processes.In industrial applications, water treatment is also vital to protect downstream equipment from fouling, scaling, corrosion, and other forms of damage or premature wear due to contaminants present in the source water. For these reasons, cooling tower and boiler feed water are generally pre-treated. Membrane filtration is also utilized to treat non-potable water sources such as gray water and reclaimed/recycled “purple pipe” water. Because the membranes are made using thin, porous sheets of material, failing to sufficiently pre-filter any large, suspended particles from the water can cause severe damage and fouling – leading to premature replacement and unnecessary maintenance, according to Robert Presser, vice president of Acme Engineering Products, Inc., a North American manufacturer of industrial self-cleaning strainers.“Most membrane filter manufacturers recommend that all influents be pre-screened from 100 to 500 microns to maintain membrane filter efficiency,” says Presser, whose company is an ISO 9001:2015 certified manufacturer of environmental controls and systems with integrated mechanical, electrical and electronic capabilities.He adds that automatic scraper strainers are typically installed before the intake plenum of membrane filters, after the supply pumps.EXTENDING MEMBRANE LIFEAs an alternative to sand filters, centrifugal separators, and basket type strainers, automatic scraper strainers provide superior membrane protection while drastically reducing required maintenance.Automatic scraper strainers like those from Acme Engineering can provide continuous removal of suspended solids to comprehensively protect membrane systems. The automatic units are motorized and designed to continually remove suspended particulates in industrial process water and wastewater to the specific size required down to 0.003 inches (75 microns).Conventional manual strainers can become clogged quickly due to limitations in straining area. When that occurs, cleaning or media replacement is required, which increases maintenance costs. The other alternative for fine straining is automated backwash-style strainers of various designs. As particle sizes grow larger, however,

Page 26

22 | APRIL 2022WWW.MPTMAG.COMMPTWATER & WASTEWATER FOCUSWATER & WASTEWATER FOCUSlarge contaminants can jam up the backwash system or remain in the body of the strainer, requiring manual removal and interruption of the process flow.With the automatic scraper strainer, cleaning is accomplished by a spring-loaded blade and brush system, managed by a fully automatic control system. Four scraper brushes rotate at 8 RPM, resulting in a cleaning rate of 32 strokes per minute. The scraper brushes get into the wedge-wire slots and dislodge resistant particulates and solids. This approach enables the scraper strainers to resist clogging and fouling when faced with large solids and high solids concentration. It ensures a complete cleaning and is very effective against even organic matter “biofouling.”With this type of system, manual maintenance for cleaning is eliminated. Blowdown occurs only at the end of the intermittent scraping cycle when a valve is opened for a few seconds to remove solids from the collector area. Liquid loss is well below 1 percent of total flow. With so much to gain, industrial plant managers should consider selecting an automated, self-cleaning system that is essentially “set-and-forget,” where automatic scraper strainers comprehensively protect delicate membranes and allow personnel to focus on other aspects of the facility. DEL WILLIAMS is a technical writer who lives in Torrance, California. Acme Engineering Products offers a wide range of standard product boilers but distinguishes itself by providing custom solutions with ease and minimal additional cost. Acme has always produced packaged solutions that include controls and instrumentation. This required the development expertise in pressure vessel design, on which its boilers’ technology is based, to complement the electrical engineering for its heating and control systems.

Full annular rub was simulated with three types of rub head materials. These three rub materials are aluminum, brass, and plastic. The experiment was carried out under three speeds, i.e., 1,000; 2,000; and 3,000 RPMs. Acceleration signal on bearing housing were collected and analyzed. Several observations about the effect of rub on bearing housing vibration were presented. INTRODUCTION For rotating machinery, rub is an undesired contact between a rotating and stationary part. It causes direct damage to the contacting parts. The damage can range from mild, for light rub, to complete destruction of the machine. Generally, rub is caused by some malfunction that produces a shaft/rotor and stator contact. Some examples of the malfunction which can cause rub include: excessive radial loads, looseness, misalignment, etc. The rub can be divided into partial radial rub and full annular rub. When the actual rub contact occurs over a fraction of the vibration cycle, it is called partial rub. When it occurs over the entire vibration cycle, maintaining continuous contact, it is called full annular rub. How to identify the vibration signature caused by rub on bearing housing is very critical in preventing rub related machinery failure. Also, the effects of rub material and speed on vibration signature associated with rub are two other key issues. In this work, efforts are made to answer the above questions by simulating rub in a controlled way. EXPERIMENT SETUP Shaft rub was simulated on a Machinery Fault Simulator (MFS) with a rub kit. The rub kit is illustrated in figure 1a. This kit permits the simulation and evaluation of typical rub phenomena associated with a variety of materials under different angle, loading, and lubricant conditions. The kit consists of an adjustable tool holder for the rub material, a vertical post, a horizontal bar, and clamping mechanism. A spring inside the tool holder is compressed and exerts a moderate pushing force which presses the rub head against the shaft or rotor surface (figure 1b). Therefore, the rub head will maintain continuous contact with the shaft all the time. The type of rub simulated with this rub kit is full annular rub. The shaft in the MFS is 5/8 inches in diameter and made of steel. It is supported by two rolling element bearings. During the test, the shaft is not connected with any other components except the motor. Three types of rub head materials were tested in this work. They are aluminum, brass, and plastic.

APRIL 2022 | 25WWW.MPTMAG.COMMPTexperiment was carried out under three speeds, i.e., 1,000; 2,000; and 3,000 RPMs. Two accelerometers were installed on each of the two bearing housings in horizontal and vertical directions respectively to collect the vibration data as illustrated in figure 2. EXPERIMENTAL RESULTS The vibration signal used for displaying and analyzing in this section is from the acceleration on the inboard bearing housing in the horizontal direction. Figures 3a and 3b display the baseline and shaft rub (aluminum rub head) vibration waveforms with the same time period at 1,000-RPM speed respectively. The amplitude range of figure 3a is 1.2e-2. The amplitude range of figure 3b is 2.4e-1. The vibration amplitude of bearing housing increases significantly with rotor rub for 1,000 RPMs. Figures 4a and 4b display the baseline and shaft rub (aluminum rub head) vibration waveforms with the same time period at 3,000-RPM speed respectively. The amplitude range of figure 4a is 1.1e-1. The amplitude range of figure 4b is 3.7e-1. The vibration of the baseline and rub one have the same amplitude level. Comparing figure 4 and figure 3, it can be noticed that the vibration amplitude of bearing housing of the baseline increases significantly with speed. The vibration spectrum of bearing housing without rub and with rub (different rub head materials) for 1,000 RPM-speed are illustrated in figure 5. Figure 5a is the spectrum without rub. Figures 5b, 5c, and 5d are the spectrums for rub head materials of plastic, aluminum, and brass respectively. From figure 5, it can be noticed that the spectrum with rub has significant difference to that without rub. A careful inspection of figures 5c and 5d indicates that the spectrums for rub materials of aluminum and brass are similar to each other. The spectrum for the plastic rub material has a unique characteristic as illustrated in figure 5b. In figure 5b, there is a dominant resonance component close to 2KHz. Figures 5c and 5d suggest that the spectral Figure 4: Baseline vs. rub vibration waveform for 3,000 RPMs.Figure 3: Baseline vs. rub vibration waveform for 1,000 RPMs. ABAB

26 | APRIL 2022WWW.MPTMAG.COMMPTMAINTENANCE & RELIABILITYMAINTENANCE & RELIABILITYcomponents for the aluminum and brass rub materials are much more complicated than the case of plastic rub material. A lot of structural resonances are excited by the rubbing with these two materials. A comparison of figures 5b, 5c, and 5d indicates that there is a common resonance excited around 900Hz. The vibration spectrum of bearing housing without rub and with rub (different rub head materials) for 2,000-RPM speed are illustrated in figure 6. Comparing figure 6 with figure 5, similar bearing housing vibration signatures can be observed. The plastic rub generates a dominant resonance component around 2KHz. The spectrums for the aluminum and brass rub materials are close to each other. And a common resonance around 900Hz emerges much more clearly in figures 6b, 6c, and 6d. However, the amplitude difference between baseline and rub cases decrease. In figure 5a, the baseline vibration is very low. However, the baseline vibration in figure 6s cannot be neglected. The vibration spectrum of bearing housing without rub and with rub (different rub head materials) for 3,000-RPM speed are illustrated in figure 7. Figure 7 indicates that with the continuous increase in speed, the baseline vibration has increased to the same level with the rub cases. The spectrums below 600Hz for the baseline and all the three rub cases are very similar. The difference between baseline and rub spectrum are in the high frequency range. The rub excites high frequency structure resonance which is illustrated clearly by the frequency components above 600Hz in figures 7b, 7c, and 7d. Comparing figure 7 with figures 5 and 6, the spectrums for the plastic and aluminum rub have the largest changes. Interestingly, it seems their spectrums switch characteristics between figure 7 with figures 5 and 6, i.e., figure 7b is similar to figures 5c and 6c and figure 7c is similar to figures 5b and 5b. SUMMARY AND OBSERVATIONS In this study, the vibration signature of rotor rubbing was studied by applying a rotor rub device on a Machinery Fault Simulator. Full annular rub was simulated with three types of rubbing head materials. The three rub materials are aluminum, brass, and plastic. The experiment was carried out at three speeds, i.e., 1,000; 2,000; and 3,000 RPMs. Acceleration signal on bearing housing were collected and analyzed. From this experiment, it can be observed that rub generates high frequency structure resonances. Although the profile of the vibration spectrum caused by rub with a certain material will change with the speed, the excited structure resonance positions do not change. Under a certain speed, a specific structure resonance might be more dominant in the vibration spectrum caused by one rub material than those caused by other materials.

28 | APRIL 2022WWW.MPTMAG.COMMPTMAINTENANCE & RELIABILITYMAINTENANCE & RELIABILITYVesconite Bearings hopes to be part of the global program to reduce lead exposure from drinking water. It produces products resistant to corrosion-combatting chemicals (which are necessary to reduce lead leaching into the water system). It also provides lead-free bearing materials for pumps and water systems.Fuel and paint were the most important sources of lead exposure in many countries. But, with lead removed or likely to be removed from these sources, drinking water has become an integral source of controllable lead exposure. Global governments are increasingly drawing attention to lead in water systems and setting guidelines and regulations for control. MORE THAN ONE SOLUTION NEEDEDA staggered, multifaceted approach towards getting rid of lead in water systems is required due to the legacy use of lead in water systems. For governments, utilities and households, preventing exposure to lead can mean:• Using chemical corrosion measures to reduce the level of lead in drinking water• Flushing pipework where water has been standing for long periods in a lead pipe• Replacing old lead service linesLEAD-FREE SOLUTIONS TO REDUCE EXPOSURESVesconite’s bearing materials play a key role in combatting dangers to drinking water BY DEBORAH SPICER, VESCONITE BEARINGS

APRIL 2022 | 29WWW.MPTMAG.COMMPT• Ensuring that all new pipes and fittings are lead-free and that the solder is of a lead-free varietyCHEMICAL-CORROSION DOSINGFor many countries, lead-service-line replacement is prohibitive because of the cost. Such is the case with the United Kingdom, for instance, where the cost of replacing lead piping has been estimated at between eight and ten billion pounds.Lead service lines and components need to be replaced in the long term, but the short- and medium-term strategy is to reduce the likelihood of lead dissolving in the system by introducing a corrosion inhibitor, most commonly orthophosphate.Vesconite can play a role in a corrosion-reduction strategy to combat lead exposure. Its bearing products are resistant to most chemicals and will not degrade in water systems. At the same time, Vesconite has the benefit of being lead-free and will not introduce additional lead into the system.Orthophosphates and Vesconite products work particularly well where organic material is removed from water systems, since orthophosphates may increase bacterial growth on some plastics.INSTALLATION AND REPAIR OF WATER SYSTEMS Some countries have introduced legislation affecting the installation and repair of water utilities. This ensures that no additional lead is introduced into the water system and that there is a reduction in the quantity of lead in the system.Such is the case with the United States Safe Drinking Water Act which prohibits the “use of any pipe, any pipe or plumbing fitting or fixture, any solder, or any flux, after June 1986, in the installation or repair of (1) any public water system; or (2) any plumbing in a residential or non-residential facility providing water for human consumption, that is not lead-free.” For utilities implementing this policy, Vesconite’s Hilube bearing material has NSF61 approval for use in potable water applications.This certification should provide comfort and assurance to utilities that need to abide by the US’s Environmental Protection Agency’s (EPA) final regulation on the “Use of Lead-Free Pipes, Fittings, Fixtures, Solder, and Flux for Drinking Water.” The September 2020 regulation requires that manufacturers and importers of components used in drinking water systems certify their products have met the requirements of the regulation within three years of the final rule publication date.REPLACEMENT OF LEAD SERVICE LINES AND COMPONENTSStrategies on whether lead service lines and lead components must be replaced entirely or partially differ between and within countries.

Page 34

30 | APRIL 2022WWW.MPTMAG.COMMPTMAINTENANCE & RELIABILITYMAINTENANCE & RELIABILITYFor instance, Southern Germany prohibited lead pipes more than 100 years ago, while Northern Germany, which continued to use lead piping into the 1970s, is currently focusing on getting rid of lead service lines.There seems to be a worldwide groundswell of interest in replacing lead piping since piping is the main cause of lead contamination in water systems. Other parts of the water system, while they may not be the priority source of lead exposure, are also not being ignored. Solder, fittings (including alloy fittings with high lead content), and service connections contribute to lead in tap water and remain a concern for the World Health Organization, as indicated in its Guidelines for Drinking-water Quality.Lead-containing bronze, for instance, has been seen as problematic for the bearings and impellers contained in pumps and water systems. Alloys such as zinc, tin or aluminum have sometimes replaced lead—this replacement will benefit the health of countries that introduce such products but these alloys tend to be adversely affected by chlorine dosing over an extended time. However, should lead-free, chlorine resistant, long-lasting Vesconite bearing materials replace these materials, they would lower maintenance time and costs while at the same time reducing lead exposure. SOLUTIONS TO LEAD IN DRINKING WATERDifferent countries have set the allowable quantities of lead in drinking water. However, the lower the levels the better. There are no safe levels of lead, say experts. This statement is notably true for children who can experience behavior and learning problems, lower IQ and hyperactivity, slowed growth, hearing problems, anemia and, in rare cases, seizures, comas, or death with even low levels of lead in the blood.However, lead exposure does not need to be a permanent threat to the world’s potable water supply. The tools are already available to combat the problem as is the will to take it on. All that is needed today is to bring the two together. FURTHER READING1.

APRIL 2022 | 33WWW.MPTMAG.COMMPTmain feedwater pump with a single-stage design.Sulzer won the tender to design, supply, test, install, and commission six complete main feedwater pump trains for the nuclear power plant. In China, Sulzer’s Suzhou plant is one of the latest manufacturing sites to open for the company and provides the local power generation market with access to its global network of engineering experts. The project was delivered by the team in Suzhou and involved support from the company’s facilities in Switzerland, Germany, and the United Kingdom.DEMANDING SPECIFICATIONSFrom the outset, the specifications for the main feedwater pumps were very demanding. Specifically, the vibration limits, which were set at 0.11 inches per second for the preferred operating range (POR) and 0.17 inches per second in the allowable operating range (AOR), including the maximum speed at 30 percent of BEP flow.The pump Sulzer selected for this challenging application was the HPTd main feedwater pump, supported by a HZB booster pump, supplied with a fluid coupling and an 11.6 MW drive motor. The single stage delivers over 2,000 feet of head and had to be precisely designed and engineered to pass the demanding test schedule.The engineering procurement and construction (EPC) company in this case was responsible for overseeing the manufacture of the main feedwater pumps. As part of this process, Sulzer needed to complete a number of comprehensive test routines to validate the performance of the design. Of the first set of three One of the feedwater pumps underwent a thermal shock test as part of the project delivery.

34 | APRIL 2022WWW.MPTMAG.COMMPTPUMP SOLUTIONSPUMP SOLUTIONSHPTd pumps, one was put through a hot test to verify its optimum operation when pumping water at 356 to 392 degrees Fahrenheit (180 to 200 degrees Celsius); then it was subjected to a thermal shock test and finally it was assembled into a purpose-built test loop and a full string test was completed.ENSURING A SIXTY-YEAR SERVICE LIFEThe testing requirements for these pumps were very detailed and required considerable investment from Sulzer, but were essential in order to meet the expected service life of sixty years.One of the major criteria that needed to be achieved was the overall efficiency of the pump. This is primarily a feature of the equipment’s hydraulic design, although the drivetrain does have an effect on the final figure. In projects such as this, the EPC issues the build specification, part of which will state the minimum efficiency figure for the pump. Today, these are typically above 85 percent and for pumps of this scale, achieving the criteria can be a challenge for some manufacturers.For Sulzer, using its in-house expertise and applying it to a proven pump design enabled the company to deliver a pump that exceeded expectations. In terms of overall efficiency, the highly engineered design achieved a full one percent higher in the actual efficiency than the specification, which will deliver significant additional savings in running costs.ACHIEVING LOW FLOW OPERATIONThe specifications for the vibration figures were very stringent, especially considering the size of the pumps. However, the requirement for a vibration level below 0.17 inches per second when the flow is at 30 percent of BEP is a significant challenge. Typically, the minimum flowrate would be higher, making the target vibration figure easier to achieve.The design of the main feedwater pumps was led by Sulzer’s Product Development Team working seamlessly with the Order Related Engineering group in Suzhou. The pumps were then manufactured and tested in Sulzer’s Suzhou facility.For every component of a nuclear installation, the traceability of the materials used in their manufacture is essential. The supply chain validation process means that the procurement procedures can be protracted, but as one of the world’s leading pump manufacturers, Sulzer has considerable experience in meeting all the demands of such a challenging project.PRECISION ENGINEERING SOLUTIONSThe combined facts of the exceptional efficiency figures and the achievements with regard to the outstanding mechanical performance, all point to the precision engineered hydraulics made up of the pump casing and impeller, which have enabled these targets to be surpassed.The Chinese nuclear market is very competitive, and the EPCs are looking to deliver the best possible solutions for operators.Sulzer has continuously invested in its capabilities in Suzhou to enhance its offering of highly engineered pumps for the most demanding applications. The latest additions to the testing facilities will strengthen its support for customers in a wide range of industries including power generation and specifically the nuclear business.Sulzer’s pumps can be engineered to suit the specific performance characteristics of each application. Further, the design, procurement, manufacturing, and testing processes have been thoroughly validated to meet the strictest industry requirements such as those of nuclear installations.

It opens new opportunities for motion control design within the medical devices and technology industries.The new piezomotor provides exceptional resolution, fast response time, ultra-smooth motion—without the vibrational interference caused by traditional DC stepper motors. The motor design enables accurate angular positioning and the ability to maintain any set position without the need for applied power, characteristics that are essential for many medical devices and high-tech applications. Until now, precision miniaturized positioning devices have relied solely upon rotary electromagnetic (EM) motors (e.g., stepper motors).CONVENTIONAL STEPPER MOTIONA conventional DC stepper motor is essentially a brushless DC motor (BLDC) in which a full 360-degree rotation is divided into several equal steps. Stepper motors have multiple electromagnets arranged as a stator around a central magnetic rotor which is connected to the motor shaft. The rotor looks like a cog wheel in design because it has raised cogs/teeth around its circumference. When the electromagnets are energized (e.g., an external driver circuit), they attract the nearest cog. The rotation of the rotor is controlled by the sequential energization of each electromagnet. This occurs when the cog is attracted to the first electromagnet. The next electromagnet is turned on. The first is turned off, causing the rotor to rotate to align the cog with the second electromagnetic. The process is repeated to the next electromagnetic, causing rotation. Each of those rotations is essentially a step combined to form a full rotation.TINY MOTOR, BIG IMPACTPiezomotor creates new opportunities within the medical device market BY MARK BRODERICK, PHD, PIEZO MOTION CORP. MINIATURE PIEZOMOTORThe miniature piezomotor developed by Piezo Motion provides significant advantages in motion control applications that demand small size, high performance, precision motors.

APRIL 2022 | 37WWW.MPTMAG.COMMPTDRAWBACKS OF CONVENTIONAL DC STEPPER MOTORSDC stepper motors move in discrete steps in response to electrical step and direction pulses. They are often distinguished by size, torque rating, speed, and/or the angle of the step. Typical stepper motors have a step angle of between 1.8 degrees and 0.72 degrees, providing between 200 to 500 steps per full rotation. These large step sizes create motor vibration leading to poor smoothness of rotation, mechanical noise, and resonance problems. The problem is even worse at slow speeds, which amplify the unevenness of rotation of the stepper motor. One way to alleviate this lack of smoothness and mechanical noise is to reduce the size of the stepper motor’s steps. This is achieved using a technique called microstepping, which enables the motor to rotate less than one complete step—often between 16 and 256 microsteps per one full step, thereby providing up to 51,200 microsteps per full rotation. Microstepping is achieved using a pulse-width modulated (PWM) voltage to control current to the motor and requires more complicated and costly control circuitry.One fundamental problem with microstepping is that as you increase the number of microsteps per full step, the incremental torque per microstep decreases substantially. For example, at 16 microstep the holding torque is lowered by 10 percent of the original torque at a single full step, as the number of microsteps increases the torque rapidly decreases by more than 70 percent. The drawbacks of stepper motors get worse with smaller frame sizes. Miniature high precision stepper motors are complicated to manufacture and can be unreliable and expensive. Generally, most stepper motor suppliers offer frame sizes in the range of 0.78 to 3.5 inches (NEMA 8 to NEMA 34). Precision Stepper motors smaller than 0.78-inch frame size are difficult to find and costly.THE NEW PIEZOMOTOR SOLUTIONThe need for an alternative rotary motor that can overcome these limitations has been met with the development by Piezo Motion of a novel high-performance miniature rotary piezomotor, the model RAS. reinforced engineering thermoplastics, and with a rotor diameter of just 0.44 inches, this piezomotor provides superior precision and ultrafast response/start-stop characteristics; all within an affordable design. The motor is highly energy-efficient and consumes zero power in hold position while still providing significant torque. What is exciting about the new motor is its minimum step size of just 30 μrad, which equates to more than 200,000 steps per full rotation of control. Furthermore, unlike a microstepping stepper motor which loses more than 70 percent torque during a microstep, the piezomotor maintains full torque during every step and provides ultra-smooth and silent rotation. With a reaction time of fewer than thirty microseconds, the piezomotor is at least 100-times faster at responding than a stepper motor.A simplified model of new piezomotor illustrating the principle of rotation using a rectangular piezoelectric resonator electrically excited to create rotation of the bearing.

The patented principle of excitation uses two orthogonal vibration modes. The two modes of vibration cause the piezo ceramic to oscillate and create rotation of the rotor which is pushed against the piezoceramic. The technique greatly simplifies drive circuit design and requires very low voltages, reducing the drive electronics cost.The new piezomotor is the ideal choice for OEM applications where superior performance and competitive unit cost are important factors. Available in a variety of configurations, including hollow-shaft, solid shaft and with/without integrated encoder, they provide superior performance compared to a conventional stepper motor. The piezomotor provides micro-radian resolution, ultra-smooth rotation, and zero backlash. The use of engineering thermoplastic in the design enables the motor to be manufactured with non-magnetic materials, making it suitable for MRI and other applications where high electromagnetic fields may be present.

APRIL 2022 | 39WWW.MPTMAG.COMMPTCONTROL OF MOTIONThe Piezo Motion motor is straightforward to control using an external signal source on the motor driver board. A digitally controlled AC voltage source applies a train of electrical pulses directly to the piezoceramic. Motor speed is controlled by changing the sequence or duration of the pulses (i.e., PWM). Modulation of the excitation voltage source enables switching between a continuous rotation to a precise stepping mode.The piezomotor electronic driver PCB has been designed to provide an economical user-control interface.

APRIL 2022 | 41WWW.MPTMAG.COMMPTmore convenient and better for the environment than flying halfway round the globe for a half-day conference, there are some things that, according to conventional wisdom, can only be carried out successfully in person.TECHNOLOGY TO THE RESCUEUntil recently several stages of production and installation of manufacturing equipment would have fallen firmly into this category. Clients would have travelled to manufacturer’s facilities to carry our Factory Acceptance Testing (FAT) as new projects were begun, and manufacturer’s engineering staff would visit the client to assist with the final installation and commissioning of the finished equipment. Over the last two-years COVID-19 has made many of these trips impossible, or harder to justify.Technology has once again come to the rescue, with remote metrics and connections to machinery and equipment allowing the equipment manufacturer’s own staff to assist local onsite engineers with the connection, installation, and commissioning of new equipment. Over the last two years HRS Heat Exchangers have used such an approach at both national and international levels to assist with the installation of a wide range of equipment FAT helps verify that newly manufactured and packaged equipment meets its intended purpose, validating the operation of the equipment and making sure that customers’ purchase order specifications and other requirements have been met. Later in the supply process, commissioning can be defined as a systematic process of verifying that all equipment and facilities perform interactively in accordance with the design and intent, and in accordance with the client’s operational needs, including the preparation (and training) of operational personnel. It is usually carried out between the design phase and up to one year after installation.INDUSTRY 4.0 AND VIRTUAL INSPECTIONThanks to remote telemetry, engineers and others can perform virtual inspection of assets and can see virtually what works and what doesn't, including “fault” finding and identification. These digital solutions help to reduce the number of personnel on site as well as the duration of tests and can be applied to both FAT and final commissioning.Remote commissioning is becoming one of the most visible

Although each case will be different, there are a number of stages which are common to most remote commissioning processes, including verification that the plant or equipment has been installed in accordance with the plans and piping/instrumentation diagrams. There is also likely to be a pre-commissioning stage that includes systematically checking connections, wiring and human-machine interfaces (HMIs) as well as installing and updating software components, cleaning, flushing equipment, etc.The actual remote commissioning process will also consist of various steps but is greatly assisted by remote monitoring and telemetry of equipment using either an ethernet connection or an integrated data SIM. This allows system software to be adjusted as necessary while the equipment is operating. Other parameters and physical adjustments can be discussed during online meetings facilitated by conferencing systems and other forms of communication, such as WhatsApp. To date HRS has carried out a number of successful projects have demonstrated the effectiveness of this approach.THE BENEFITS COMPOUND OVER TIMEOne practical aspect which must be considered when operating internationally is the potential time difference between the on-site engineering team and the equipment supplier and overcoming this presents some logistical challenges and additional costs. However, none of these issues are insurmountable. When additional out-of-hours overtime charges are compared to the costs of travel and accommodation, there are often financial benefits, not to mention to considerable the reduction in carbon emissions and unproductive time spent travelling. These benefits are undoubtedly one of the drivers which will ensure that remote commissioning continues to be carried out in the future whether or not our ability to travel is limited by the COVID-19 pandemic or other unforeseen factors.

46 | APRIL 2022WWW.MPTMAG.COMMPTCOMPANY PROFILESCOMPANY PROFILESBlacohRedesigned from the inside out, Blacoh back pressure and pressure relief valves feature patent-pending flow stabilization technology to deliver improved flow, extend valve service life, and eliminate dreaded valve chatter.Blacoh engineers solved the problem of valve chatter with a better design. Most back pressure valves are based on a pressure relief design where the valve is normally closed. When a set pressure point is reached, the valve opens quickly with maximum flow to relieve pressure. This action doesn’t work well for back pressure valves that need to flow continuously to hold pressure upstream. When the valve opens quickly, pressure upstream drops rapidly and the valve slams closed. The sudden stop in flow causes a pressure spike that forces the valve open again. In a back pressure valve application, this cycle occurs many times per second, creating a loud, chattering valve with inferior performance and a shorter service life. Blacoh’s flow stabilization technology meters flow when the valve opens to minimize the pressure drop that initiates this cycle. The result is a valve that doesn’t chatter, performs better, and lasts longer.All Blacoh back pressure and pressure relief valves use a unique swiveling spring seat to ensure spring force is applied evenly over the diaphragm for more consistent and complete valve closure. Both plastic and metal valves have a separate ring attachment that provides a more uniform clamping load and improved seal performance. Standard plastic valves use a threaded connection, eliminating the need for metal fasteners. Blacoh valves are available in sizes from 1/4 up to 2 inches in a variety of materials, port configurations, and inlet options, with spring pressures up to 350 psi.

48 | APRIL 2022WWW.MPTMAG.COMMPTCOMPANY PROFILESCOMPANY PROFILESEnvironment One CorporationE/ONE BACKGROUNDFor more than fifty years, Environment One Corporation has manufactured 1 horsepower SPD grinder pumps designed specifically for use in pressure sewer systems. From the 200 Series in the 1970s to the 2000 Series in the 1990s to today’s Extreme model, almost two million end users in over forty countries rely on E/One grinder pumps daily.SPD GRINDER PUMP FOR WASTEWATER APPLICATIONSIn a low-pressure sewer system, constant, predictable pump output is the foundation for proper hydraulic design. It enables the engineer to minimize retention time, pump wear, and keep scouring action at effective levels. The system pressures to be overcome by any given grinder pump in a low-pressure sewer system vary dramatically over the course of a day. E/One’s progressing cavity pump readily accommodates these pressure variations while maintaining a nearly constant flow without ever operating at “near shut off”—thus avoiding the wear and motor burnout suffered by other pump types.E/One’s SPD pump has a nearly vertical H-Q curve. It is by far the most “forgiving” pump design—providing predictable flow over the full range of typical system pressures; strengths critical in large-scale, low pressure sewer systems.E/One’s superior high head capability allows a system to have few, if any, lift stations. And, it easily accommodates additional future connections without compromising system performance. E/One grinder pumps offer reliable operation from negative heads to 185 feet of total head.SEWER ANYWHERE, IN ANY TERRAINPressure sewer systems are cost-effective and can be installed in any terrain—flat, wet, rocky, even on sites with dramatic elevation changes. They are much more affordable than conventional gravity sewers, which require major excavation, and much safer for communities than septic systems, which can eventually fail, polluting ground and recreational water and endangering public health. Pressure sewer systems can cost as much as 80 percent less to install vs gravity sewers and reduce the number of lift stations required—or even eliminate lift stations altogether. SEPTIC TO SEWER CONVERSION PROJECTSE/One sewer systems have been chosen for septic-to-sewer conversion projects both in the United States and abroad, especially in coastal areas where the soil is not conducive to septic tank usage and as sea levels rise. At Rincon Point in California, failing septic tanks at oceanfront homes polluted the ocean. Surfers were getting sick and avoided the water after rainstorms. One resident could see the tide rise and fall inside his septic tank. Septic tanks were replaced with the E/One sewer system, resulting in a cleaner ocean.PRESSURE SEWER SYSTEM UPGRADESE/One offers its grinder pump as a replacement for existing pressure sewer systems. E/One grinder pumps use integrated pressure switches instead of floats, which are less susceptible to grease buildup and eliminate nuisance alarms that result from stuck floats. The Upgrade is a one-piece pump that installs quickly and easily into the existing tank.Environment One’s Upgrade, the aftermarket grinder pump that works and goes on working without any preventive maintenance. It’s the original grinder pump design, the one others have tried to copy but they just haven’t gotten it right. Maybe that’s why E/One’s Upgrade has been the pump of choice for many pressure sewer upgrade projects in the mountains of Tennessee, the lakes of the Midwest, and many coastal communities.

Vaughan Chopper PumpsPumps should be reliable. Not only do they serve a vital purpose for many industries, but they are also often located in tough-to-reach areas. This makes replacing a broken pump difficult, time-consuming, and expensive—both in terms of the pump itself and the clean-up of the area around it. Vaughan Company’s high-performing and exceptionally reliable chopper pumps can handle the severe workloads of correctional facilities, dairy farms, wastewater treatment plants, and more. Because these pumps are American-made and sourced, they support American jobs and companies as well as reduce lead times and costs incurred from international suppliers.FROM THE PACIFIC TO THE ATLANTIC AND EVERYWHERE IN BETWEENIn the late 1950s, Jim Vaughan, the company’s founder, spent hours in the bay of the service station he owned in Elma, Washington, repairing manure pumps for local dairy farmers. The pumps constantly broke down due to clogs caused by animal bedding and twine. Jim asked himself what could make these pumps better. He knew there had to be a solution, so he invented the world’s first chopper pump. After he officially introduced it in 1960, Vaughan Company was born.In the early years of the company, Jim would strap a pump on the back of his pick-up truck and drive to dairy farms across the United States to give demonstrations. In the decades since, the company has sold Vaughan Chopper Pumps all over the world and has been awarded over thirty patents. The company is still located west of Elma in Montesano, Washington, and remains committed to precisely manufactured chopper pumps that can withstand the toughest applications. In addition to multiple centrifugal chopper pump configurations like horizontal, pedestal, submersible, and the world’s only self-priming chopper pump, Vaughan Company also manufactures the Triton screw pump and the Rotamix hydraulic mixing system. BENEFITS OF BUYING AMERICAN-MADEVaughan products begin with raw materials that are nearly 100 percent sourced locally in the United States. This reduces shipping time and cost, so customers across the nation can get these industry-leading products without the mark-up and wait times associated with imported systems. This is important since each chopper pump or mixing system is custom-built to meet the end-user’s specific needs. Even without current supply chain disruptions, global sourcing would not allow for this level of customization within a feasible timeline. In addition to fast builds, the Washington-based manufacturing facility holds a large surplus of spare parts, so Vaughan products are easily maintained.Knowing every pump user faces a unique situation, Vaughan Company also has local sales representatives across the country to provide exceptional customer service when it is needed most—whether that is working closely with customers to tailor pump solutions for an exact situation or providing post-installation support. PRODUCTS THAT SUPPORT AMERICAWhile Vaughan’s locally sourced and American-made chopper pumps keep projects moving, their benefits don’t stop there. Vaughan Company has been family owned and operated for four generations and is still asking Jim’s question, “What could make this better?” The company’s commitment to continuous improvement has led to products that are efficient and reliable. The company uses cutting-edge technology like 3D computer modeling, which helps create exacting fits and precision castings for all components. Always pushing boundaries, Vaughan Company also uses both computational fluid dynamics (CFD) to analyze flow patterns and velocities within the pumps to maximize their performance and computer numerically controlled (CNC) automated machining to ensure every Vaughan replacement part fits precisely and consistently. But the answer to Jim’s question extends beyond the walls of the manufacturing facility. As a major, local employer, the company strives to better its community by giving to charities and community organizations. Vaughan Company developed its own scholarship program for graduates of the Elma or Montesano school districts, who are planning to pursue a post-secondary degree or technical certificate and supports many industry associations to help provide scholarship opportunities in the water and wastewater sector. Vaughan products are not just made in America, they also support the future of America.

APRIL 2022 | 61WWW.MPTMAG.COMMPT2022 | PRODUCTS & SERVICES GUIDEHelwig CarbonMany pumps utilize a variable frequency drive (VFD) to increase pump motor efficiency. While VFDs lower power consumption, they also induce currents onto the motor shaft. These shaft currents will often discharge through the motor bearings causing fluting, burnt grease, and eventual bearing failure. Downtime, repairs, and warranty claims can be the result of bearing failure and can be extremely costly to any company.Helwig’s BPKs (Bearing Protection Kits) have been leading the industry in shaft grounding solutions for years. Our proven silver graphite brush technology is unlike other shaft grounding system because it eliminates the need for maintenance and will keep bearings protected year-after-year. Helwig BPKs effectively divert induced electrical currents away from the bearings, protecting them from damage and failure. What’s more, our BPKs are economical, easy to install, and can be used on almost any electric motor application! Another unique feature of the Helwig BPK solution is that one size fits most! While other shaft grounding systems need a different grounding ring for each motor shaft size, the same BPK can be applied to a variety of motor models. Our MultiFit Bracket mounting system allows for a BPK to be attached to multiple bolt designs while keeping constant contact on the motor shaft. With the success of Helwig’s BPK shaft grounding solution, the innovation has continued. Helwig Carbon’s Shaft Voltage Detection Device, otherwise known as the BPK-Probe™, is an instrument designed to measure common mode voltage on a motor shaft. Test results from the BPK-Probe will inform a user if there is current present on the motor shaft, and, therefore, show the risk of bearing damage due to electrical discharges. The patented instrument also has the capability to demonstrate the effectiveness of Helwig’s Bearing Protection solution. This feature allows the user to mimic the installation of a BPK and then measure the voltage present on the shaft, proving that the parasitic shaft current is being instantly grounded through the silver graphite brush. The BPK-Probe is an excellent tool for any engineer, technician, or preventative maintenance professional that needs to evaluate motor health on a regular basis.
