10 | FEBRUARY 2024 WWW.MPTMAG.COMMPTCASE STUDIESCASE STUDIESIt’s not unusual for water utilities to expand infrastructure to address predictable population growth, but there are more factors today that are causing unexpected population changes. Many people have moved as a result of switching to working from home due to the global pandemic, and with more extreme weather events, communities can quickly shrink and conversely, rapidly expand. When this happens, water operators are often faced with new peak and off-peak periods, and demand for water can change quickly, making it more challenging to control a water distribution system’s pressure.Without proper pressure management, high-pressure incidents can occur when pumps are turning on or off or when a valve suddenly closes, sending water hammer back through a piping system. Having the right valves to manage large fluctuations in water flow is one way that utilities can balance erratic flows and stay ahead of evolving community demands.UPGRADING PRV STATIONS TO BALANCE SYSTEM PRESSUREA West Coast utility decided to change all the pressure reducing valves (PRVs) in their water distribution system that was predominantly monitored and controlled based on flow demands. With numerous line connections and pressure zones, coupled with a growing population, the fluctuating demand was putting unnecessary over pressure on the distribution system. One of the problems that needed addressing was when a downstream high-pressure event occurred, the seat of the main valve of the old flat diaphragm valves would chatter. This wear and tear resulted in the need for more maintenance to monitor and replace the valve seats in order to avoid a valve failure. The five-year PRV upgrade was designed to address the fluctuations and ensure redundant pressure and flow control through SCADA automation. By moving to Singer® PRVs with redundant pressure control (PR-SM) and single rolling diaphragm technology, the new system was designed to provide smooth, steady, and precise pressure control from THE RIGHT VALVE MAKES ALL THE DIFFERENCEWater utility manages ow uctuations with single rolling diaphragm valves BY MIKE UTHE, MUELLER WATER PRODUCTS

Page 13

FEBRUARY 2024 | 11WWW.MPTMAG.COMMPTmaximum to virtually zero flow, without the need for low-flow bypass valves. The effective area of the single rolling diaphragm remains constant, so the bonnet is much smaller and lighter than a flat diaphragm version. A measured quantity of water in the bonnet control chamber always gives the same smooth movement of the inner valve (diaphragm assembly) through the entire stroke. By eliminating the seat chatter at low flows, the SRD avoids injecting small pressure pulses into the piping, which, over time, may increase leakage, losses, or pipe bursts. Eliminating the seat chatter with the single rolling diaphragm technology means the new Singer valves are much quieter.MAINTAINING PRESSURE WITH REDUNDANT BACKUPThe new valves were fitted with electronic primary control with a hydraulic pressure reducing back-up on the loss of power, or failure of the pilot system. Typically, the city pulsed solenoids based on a flow meter to provide a constant flow rate from each PRV. The hydraulic pilot and secondary chamber operate independently of the main electronic control chamber so that if there is a failure, it can override the main valve body and maintain downstream pressures. In the event of a failure, there is now also a limit switch on top of the valve that sends an alarm to the city, so they know that they are running in backup mode. The new backup system was engineered to be used anywhere that valve failure is unacceptable.ADDING INLINE FLOW METERS TO CONTROL VALVES VIA SCADASites that did not have inline flow meters were fitted with the Singer SPI-MV, a Single Point Insertion electromagnetic flow meter that provides accurate flow data within 2 percent of actual reading. These flow sensors come pre-calibrated from McCrometer’s NIST traceable calibration lab, so they require no recalibration in the field. With a single-piece design and no moving parts, the electromagnetic sensor contains nothing to wear or break, and is generally immune to clogging by debris. The SPI-MV can also tie back into the existing SCADA system for complete flow-based valve control.

12 | FEBRUARY 2024 WWW.MPTMAG.COMMPTCASE STUDIESCASE STUDIESSPECIFICATIONS TO MEET INDIVIDUAL NEEDSEach valve replacement was uniquely specified. Depending on the consequence of failure, the redundant valve body was either selected or not. If power was available in the vault, the city was also able to add transmitters to the pilotry and valve stem so that the percentage open was available through SCADA along with real-time pressures and flows. The redundant valve body was also provided with a limit switch on a battery power supply so that the city can now receive an alarm as soon as there is a main chamber failure.CONCLUSIONManaging fluctuations in water pressure, regardless of the cause, allows utilities to provide the right amount of water when it is needed. Optimizing the hydraulic integrity of a water distribution system is also one of the most beneficial ways to extend the life of assets. With less maintenance required on the new PRVs and less possibility for failure, the city is confident it can continue to supply a steady flow of water, regardless of fluctuating demand and evolving size of the population.

14 | FEBRUARY 2024 WWW.MPTMAG.COMMPTWATER & WASTEWATER FOCUSWATER & WASTEWATER FOCUSDelta Sand and Gravel Co., located in Eugene, Oregon, has been providing quality aggregate materials, service and expertise for almost nine decades. The company offers a full line of aggregate products for year-round, all-weather construction and demolition landfill. Xylem has partnered with Delta Sand and Gravel for over a decade to provide holistic water management solutions.TAKING ON A CHALLENGEDelta Sand and Gravel has a central collection pit to handle all surface water from across its operations. The surface water is pumped to a series of five settling ponds before being safely discharged into the environment or re-used on-site. The three permanently-installed pumps, which had been in place for many years, were inefficient, and experienced frequent maintenance issues. The in-rush current at startup was also problematic, adding to maintenance problems and risking surges that could impact the surrounding power grid. Repairs on the pumps were costly and cumbersome, with a crane required to lift the pumps out of the pit. In addition, parts were becoming difficult to source, due to the age of the pumps.With plans to increase the depth of the pit by 100 feet in the coming years, Delta needed a robust, efficient and flexible pumping solution. The company had rented Dri-Prime diesel-driven and submersible pumps from Xylem previously, and they turned to us again to solve this latest challenge.HIGH-EFFICIENCY SURFACE WATER PUMPING SYSTEMReducing energy consumption by 25 percent for an Oregon aggregates mine BY JAMES DELOACH, XYLEMPROJECT SUMMARYPROJECT HIGHLIGHTS: • Design and installation of a holistic, turn-key solution including vertical turbine pumps, a floating barge, and a robust suction screen• Supporting enhanced site safety by removing the need for a crane and crew to perform regular maintenance SOLUTIONS: • Goulds Water Technology 18LHC Line Shaft Vertical Turbine Pump• Equipped with 400-horsepower motor• Customized robust suction screen• Xylem engineered and fabricated floating barge for the pumpsCUSTOMER BENEFITS: • Energy savings of 25 percent• A flexible, reliable, and high-efficiency pumping solution that is configurable to current and future pit depths• Enhanced operational efficiency and reliabilityDelta needed a robust, efcient, and exible pumping solution… and they turned to us again to solve this latest challenge.” —GOULDS WATER TECHNOLOGY REPRESENTATIVE ON-SITE“

FEBRUARY 2024 | 15WWW.MPTMAG.COMMPTTHE GOULDS SOLUTIONEnhancing pumping efficiency and resiliency at this sand and gravel operation was a top priority. One of the permanently-installed pumps in the collection pit runs 24/7, with all three pumps running simultaneously at certain times of the year when rainfall is high. Xylem recommended a turn-key solution, incorporating its Goulds Water Technology vertical turbine pumps as a highly efficient, reliable, and easy-to-operate solution. The pumps are equipped with variable frequency drives (VFDs) to optimize energy consumption, while a soft start controller facilitates a slow ramp up and addresses the large in-rush current issue. Add to this the flexibility of the pump model, which means the pumps will continue to operate at best efficiency point (BEP), even when the pit is lowered by 100 feet in the coming years.A ROBUST RESULTXylem’s turn-key solution includes pumps, a floating barge, and a robust suction screen—a comprehensive solution from a single provider to support the mine’s needs today and tomorrow. In addition to the first pump system, two new pumps are due to be operational ahead of the rainy season in fall. The robust, reliable solution resulted in a savings in energy consumption of 25 percent, compared to the old system. The low-maintenance pump model will enhance safety at the plant, reducing the need to bring a crane and crew on-site when repairs are required, and will cut costs significantly as a result. The mine operators also have the peace of mind that the pump can be configured for optimal efficiency when they lower the pit in the future.

16 | FEBRUARY 2024 WWW.MPTMAG.COMMPTMAINTENANCE & RELIABILITYMAINTENANCE & RELIABILITYLast month, we began this series by describing some of the most common reasons to implement a modern calibration process in power plants and the typical issues of an outdated calibration process. Now, we’d like to go over the most important reasons to implement a modern calibration and address the typical challenges faced by today’s power plants as they seek to bring their calibration process into the future. WHAT IS A MODERN CALIBRATION PROCESS?If we look at the most modern calibration processes available today, we can find the following key components: First, the management, monitoring and scheduling of all calibrations is automated with the help of dedicated calibration management software. The calibration management software can be linked to the CMMS for a fully automated and paperless flow of work orders. IMPROVING POWER PLANT PERFORMANCE WITH A MODERN CALIBRATION PROCESSHow to overcome the limits of legacy systems and meet today’s challenges Part 2 of 2 BY MONA-LISA GRANNAS, BEAMEXKEY TAKEAWAY #1 The most important reasons to implement a modern calibration process are to improve calibration efficiency, save costs, obtain higher quality calibrations, and be compliant with related regulations.

Page 19

FEBRUARY 2024 | 17WWW.MPTMAG.COMMPTThe calibration management software also communicates with portable documenting process calibrators, meaning that the work orders can be downloaded directly into the calibrators with all the required instructions for the technicians to go into the field. During calibration, an intelligent calibrator performs an automatic pass/fail calculation, complicated calculations do not have to be performed. Also, the results will be stored in the calibrator’s memory, and can be directly uploaded to the calibration management software. Finally, the calibration management software can automatically send an update to the maintenance management software that the work has been completed. As such, the whole process is fully paperless and more can be done with fewer resources as the process is highly automated, thus reducing costs and improving the quality of calibration data. A modern calibration process is also far more efficient, allowing more calibrations to be performed in the limited time during an outage.HOW TO IMPLEMENT A NEW CALIBRATION PROCESSThe most important reasons to implement a modern calibration process are to improve calibration efficiency, save costs, obtain higher quality calibrations and be compliant with related regulations. But how can a new calibration process be implemented? Briefly, here are a few words on implementing a new calibration process: First, it is vital to remember that implementing a new calibration process is a process itself, with many interrelated tasks that need to be performed in the appropriate sequence. A proven project supply implementation model is recommended, managed by a dedicated project manager and supported by experts in the subject matter. Without a proven implementation model, typical risks of implementing a new process are usually encountered, such as unclear expectations, budget and schedule overruns, KEY TAKEAWAY #2 Reducing the measurement uncertainty (with high-accuracy calibrators) in a nuclear power plant can potentially increase electricity production up to nearly 2 percent.

Page 20

18 | FEBRUARY 2024 WWW.MPTMAG.COMMPTMAINTENANCE & RELIABILITYMAINTENANCE & RELIABILITYscope creep, and a lack of expected benefits.Although implementing a new calibration process is far smaller in scope than implementing, for example, a new ERP system, there are still many similarities. The implementation should start with establishing the project framework in order to have a common understanding of the project targets, specify the roles of the parties in the project team and steering group, establish management rules, determine testing and acceptance criteria. This blueprinting process is an important phase where the documentation of the current process (as it is) and the target process (how it should be). During specification, you will need to document all the relevant requirements and make sure all parties have a common understanding. If all previous steps have been performed correctly, the next phase is the actual execution according to plans. Finally, the new process is put to use with secure support when in production use. Using a supplier that has a proven implementation model and which can take responsibility for the required actions is recommended.CASE STUDY: INCREASING ANNUAL PRODUCTION WITH HIGH-ACCURACY CALIBRATORS In the Central Nuclear de Almaraz (CNA) plant in Spain, an enhanced calibration system with high-accuracy calibration equipment makes it possible to perform calibration operations with better uncertainty levels, thus enabling us to improve production results. This was achieved by using the Beamex MC6 high-accuracy multifunction calibrators in the power plant.By improving the parameter measurement from 2 to 0.4 percent (parameters associated to determining reactor power), enabled power in each unit to be increased by 1.6 percent. This has a very significant effect on annual production.SUMMARYIn conclusion, modern state-of-the-art calibration process can help a power plant to improve the plant performance and efficiency, ensure safety and emissions control, and improve accuracy of invoicing related measurements. Making the calibration work more effective, automated, and paperless saves calibration related efforts and costs as well as improves the quality of calibration and regulation compliance.

It can help companies safeguard employees and comply with regulations. A wireless temperature monitoring system offers an efficient and advanced solution.KEY TEMPERATURE REGULATIONS ACROSS INDUSTRIES HEALTHCAREMedications require storage between 59 to 77 degrees Fahrenheit (15 to 25 degrees Celsius). Blood bank storage requires temperatures from 95 to 122 degrees Fahrenheit (35 to 50 degrees Celsius).PRODUCTION FACILITIES AND COMPUTER ROOMSSpecific areas must be maintained at much cooler temperatures than other parts of a facility to prevent equipment overheating that can damage computer components. ASHRAE recommends 64.4 to 80.6 degrees Fahrenheit (18 to 27 degrees Celsius) or A1 to A4 class hardware.MONITORING WHERE YOU NEED ITFive benets of wireless temperature monitoring systems BY ROB FUSCO, SENSAPHONENORTH AMERICA TEMPERATURE MONITORING SYSTEM MARKET SIZE2017-2028 (USD Billion)2017 2018 2021 2022 2023 2024 2025 2026 2027 20282019 20200.810.56

FEBRUARY 2024 | 21WWW.MPTMAG.COMMPTFOOD PROCESSINGThe USDA demands precise temperatures for stored foods. Dry grains should be stored at temperatures of 50 degrees Fahrenheit (10 degrees Celsius), refrigerated foods between 32 to 40 degrees Fahrenheit (0 to 4 degrees Celsius) and frozen foods at 0 degrees Fahrenheit (-17 degrees Celsius) THE INADEQUACY OF MANUAL TEMPERATURE TRACKINGManual temperature tracking is not only time-intensive but also error-prone. Temperature discrepancies can result in product corruption or halted operations since they can take hours to identify.And what happens if temperatures rise in a computer room or storage area after hours? Most likely, spoilage or equipment failures that result in thousands of dollars in lost revenue.The answer? A wireless temperature monitoring system.HOW WIRELESS TEMPERATURE MONITORING SYSTEMS EXCELThese systems, compared to outdated manual methods, harness advanced technology to streamline and automate temperature management. They can be utilized in facilities or within transportation fleets holding chilled products.Their rising popularity is evident in the growth from $2.19 billion in 2021 to a projected $4.71 billion by 2028, per Fortune Business Insights.WHY OPT FOR WIRELESS TEMPERATURE MONITORING SYSTEMS?More companies are installing wireless temperature monitoring systems based on the many benefits derived from it. Here are five:REAL-TIME MONITORINGFacilitates 24/7 real-time tracking, regulation, and control, even remotely via smart devices. A remote temperature monitoring system streamlines operations by enabling operators to easily track, control, and regulate temperatures in different environments simultaneously in real-time on a 24/7 basis without even entering the facility.Information is accessible from a control room or in the field from smart devices so personnel don’t have to be in the immediate vicinity to gather readings. CONFIGURABLE ALERTSInstant alerts for specific temperature thresholds to preemptively address changes. Systems are configurable to send an alarm when temperatures reach a specific threshold.Assigned personnel automatically receive alerts to take immediate action. Even a slight change in temperature will prompt an alert that gives enough time to make corrections or identify any equipment failures that may contribute to varying temperature levels.

Page 24

22 | FEBRUARY 2024 WWW.MPTMAG.COMMPTMAINTENANCE & RELIABILITYMAINTENANCE & RELIABILITYCUSTOMIZABLE THRESHOLDSAdapt temperature settings based on distinct operational needs. Users can set minimum and maximum thresholds for specific areas to customize operations. Some operations can handle larger temperature deviations while others can only tolerate minor changes so having the ability to customize specific thresholds for each application is important.DATA LOGGINGOversee temperatures over durations for compliance and quality control. Analyze data for system reliability. Companies can monitor temperatures over time for compliance reporting or to gain a better understanding of what temperatures products have experienced over time to make informed decisions about quality control. Analytic reports also provide information on spikes, anomalies, and failures to evaluate the reliability of a refrigerator, HVAC, or other system that serves to cool the environment.CONVENIENT INSTALLATIONCompared to hard-wired systems, wireless systems are easier to install and more adaptable. A wireless temperature monitoring system simplifies operations over hard-wired installations as it eliminates the need run cables from sensors and the remote monitoring system. In addition, cables may present tripping hazards in a facility or require building modifications to run them through walls, floors, and ceilings. Hardwired systems also may not be feasible in monitoring different assets in large-scale environments such as greenhouses. Installation of wireless systems also may be cheaper and faster.WIRELESS TEMPERATURE MONITORING PRODUCTSThe Sensaphone WSG30 is an efficient wireless system, especially tailored for monitoring refrigerators and freezers housing valuable items like vaccines.

24 | FEBRUARY 2024 WWW.MPTMAG.COMMPTPUMP SOLUTIONSPUMP SOLUTIONSHighly viscous substances demand robust equipment up to the task of proper handling during processing. No matter which industry, viscous media from peanut butter to polymers dictate the characteristics required of a pump properly engineered to transfer them from one processing step to the next in a productive and timely manner. Add to that wish list a pump that supplies durable performance, decreases downtime, minimizes maintenance, and gives a long service life that keeps capital expenditures under control. A gear pump can fulfill this wish list of specifications and is one viable option among pump styles to transport high-viscosity fluids in manufacturing operations. Engineered design modifications and simplified disassembly have made gear pumps suitable for hygienic applications, expanding their popularity in the food processing and pharmaceutical industry. A quick examination of the general features of a gear pump can help determine if this style pump can address your fluid handling requirements. HOW DOES A GEAR PUMP WORK? A gear pump is a positive displacement pump with a compact design that uses two gears positioned inside a pump housing. As the driving gear rotates, it draws fluid into the inlet port and carries it around the outside of the gear teeth to the outlet port. The gear teeth mesh, creating a seal between the inlet and outlet ports. Flow rate is determined by gear speed. Temperature can impact pump performance. Gear pumps are ideal for applications that need consistent or measured fluid flow. THE ADVANTAGES OF GEAR PUMPS PRECISE METERING CAPABILITIESSome gear pumps are compatible with servo motor-driven filling equipment, resulting in a pump that offers flow rates with precise metering. The gears transfer materials mechanically in a smooth, pulse-free flow using interlocking and rotating cogs or gears. This clockwork-style gear action aids WHEN TO USE A GEAR PUMPPositive displacement offers efcient viscous uid handling BY CALLE DANIELSSON, UNIBLOC HYGIENIC TECHNOLOGIESGear pumps, like this pump from Unibloc Hygienic Technologies, use interlocking gears to deliver pulsation-free flow.

Page 27

FEBRUARY 2024 | 25WWW.MPTMAG.COMMPTin the accurate metering of a fixed volume of fluids. The more compact the design and the shorter the shafts, the better the gear pump’s ability to eliminate deflection at high pressure. This particular design aids pump efficiency, flow rates and durability. When comparing gear pumps for sanitary purposes, look for close tolerances for the pump’s gear clearance. Tight tolerances allow the pump’s intake suction and the interlocking gear action to prevent slippage. The greater the slip, the more likely fluids can leak back into the inlet. Close tolerances promote tightly controlled fluid movement and more precise metering. PUMP HIGH-VISCOSITY FLUIDSThe gear pump design handles products with high viscosity or centipoise—up to 100,000 centipoises in some cases—and works best with materials that have some degree of lubricity, such as fats, oils, and glycerin, but also polymers, paints, chemicals, and petroleum products. MAINTAIN PRODUCT INTEGRITYGear pumps mitigate shear stress and degradation by exerting low shear forces on the fluids being transferred. The close tolerances between the gears minimizes agitation to preserve product integrity and quality. WHEN TO SELECT A GEAR PUMP INSTEAD OF A LOBE STYLE OR AODD PUMPA scenario that would call for a gear pump instead of an air-operated double diaphragm (AODD) pump is when precise and consistent flow rates are critical. The gear pump design allows for accuracy and uniformity when pumping fluids, such as a filling operation that requires precise volumetric control. Gear pumps are ideal for applications such as precise dosing or metering of fluids. In contrast, AODD pumps, while extremely versatile and capable of handling a wide range of fluids, may exhibit variations in flow rates due to their reciprocating diaphragm action. The same reasoning applies to lobe pumps. Lobe pumps feature a different gear configuration and can be classified as a sanitary pump also. However, lobe pumps are equipped with a bigger cavity than gear pumps, leaving them unable to accurately meter process fluid. In addition, a gear pump presents a more economical choice compared to a similarly sized lobe pump. In filling operations for example, a gear pump might cost approximately half that of a similarly sized lobe pump. WHEN NOT TO SELECT A GEAR PUMPGear pumps are not recommended for abrasive substances, which can damage or wear down the meshing gears within the pump. In addition, while gear pumps work well for

When a processing situation requires clean-in-place (CIP) operations, a lobe pump might make a better choice than a gear pump. A gear pump is designed for clean out of place (COP) processes, but the higher temperatures required for CIP can cause swelling of the Teflon-based gear in a 3A sanitary gear pump. MAINTENANCE CONSIDERATIONS FOR GEAR PUMPSMaintenance is a necessary “evil” that costs companies time and money and often requires skilled labor. Each maintenance cycle represents downtime or lost production. In addition, skilled laborers are scarce in many industries. The less time and complex pump maintenance requires or specialized tools and equipment, the better. Gear pumps do need to be disassembled to be cleaned. While generally easy to maintain, this process of taking it apart and subsequent reassembly can be challenging. Highly viscous products can cake and collect inside, particularly near the bushings. A gear pump with a clean or simplified design makes maintenance much easier for sanitary operations. This style will feature: • One-way assembly to ensure accuracy and mitigate damage• Easy disassembly in a minimal time period using ordinary tools• A pump body milled from a single piece of stainless steel• A design that eliminates front supports for a flush front cover for easier cleaning• Fully polished TIG welding to eliminate visible welds on the pumpWhen in doubt, talk to a trusted contact at a reputable pump manufacturing firm to help narrow the possibilities. It helps to find a company that has a diverse product line to pinpoint the pump style that will supply the features required. Optimize efficiencies and recoup initial costs by choosing the best pump style for your operations.

Similarly, HPUs are critical for operating industrial machinery such as tilt trailers, lifts, jacks, lift gates, boat lifts, dock locks, compactors, and cranes. However, frequent exposure to moisture from weather, washdowns, worksites, and roadways as well as humidity and other corrosion-causing factors can wreak havoc on the hydraulic component parts.IMPROVING THE DESIGNFor decades, there has been little variation in the basic component configuration of HPUs, which convert electrical power to hydraulic energy. Highly complex hydraulic systems consist of many components including manifolds, directional valves, heat exchangers, pressure gauges, and the system’s motor and pump, which are mounted to the top of the oil reservoir. Additional components such as filters, pressure gauges, and heat exchangers may also be needed to meet application requirements. While the design is technically sufficient, OEMs have long sought ways to improve the overall reliability of hydraulic systems that must operate in inhospitable, moisture-laden environments. One challenge is that high-value components like the motor and pump are also the most likely to require repair or replacement in many cases. Yet current HPU design involves mounting the motor and pump to the reservoir, which exposes the components to the environment and potential corrosion damage. INCREASING RELIABILITYEven if the HPU is in a toolbox with the vehicle battery, it is regularly exposed to moisture from various NEW SUBMERGED HPUS INCREASE RELIABILITY OF ALL HYDRAULIC POWERED MACHINERYInnovative, patented design places motor and gear pump in the oil reservoir BY DEL WILLIAMSTo provide more flexibility in design, a Submerged HPU like one from KTI Hydraulics is offered with a variety of common and customizable hydraulic circuits.

FEBRUARY 2024 | 29WWW.MPTMAG.COMMPTsources. Accelerated corrosion only leads to premature service, repair, and replacement.Since critical equipment and machinery cannot function without a sound hydraulic system, downtime and lost revenue can result as well. When this occurs, OEMs receive service calls and complaints from customers that are having problems with the unit. This can reflect poorly on the brand, lead to negative online reviews, and even a loss of future sales.In addition, while not a concern in all applications, smaller, more compact HPUs are generally preferred where space is limited.To significantly increase HPU reliability and provide greater design flexibility, a leading hydraulic parts manufacturer, KTI Hydraulics Inc., redesigned these vital components to create the industry’s first “Submerged DC HPU.” Founded in 1998, the Santa Ana, California-based company provides Hydraulic Power Units and components for use in commercial and industrial hydraulic equipment. In the patented design, the motor and gear pump are protectively submerged in the reservoir fluid, rather than the typical configuration of mounting the motor/gear pump and manifold to the top of the reservoir. PROTECTING CRITICAL COMPONENTSProtecting the motor and gear pump in this manner has many benefits. When the motor and gear pump are submerged, the high-value parts require substantially less maintenance and replacement. The new units are particularly ideal for equipment and machinery operated in harsh, wet corrosive environments. The oil also functions as coolant, resulting in a longer duty cycle.The Submerged HPU allows the OEM to change the manifold to work with a multitude of different standard or custom circuits.

The HPU includes a pressure-loaded gear pump, potted solenoid, and a reservoir with five quarts of usable volume. Several optional add-ons are available as well.The new, innovative HPU configuration also enables a more compact design (15.5 x 9.5 x 8 inch), which is ideal for OEMs looking to minimize the space required for hydraulic components.To provide more flexibility in design for OEMs, the Submerged HPU is offered with a variety of common hydraulic circuits. Custom circuits can be designed upon request. This configurable approach allows for one base unit to utilize multiple circuits. CUTTING DOWN ON REPAIRSThe Submerged HPU allows the OEM to change the manifold to work with a multitude of different standard or custom circuits. This contrasts with current HPU designs that lock the OEM into either a single-acting or double-acting configuration. For hydraulic equipment distributors, the capability eliminates the need to stock four different types of HPUs, conserving inventory space and capital. With the Submerged HPU, the distributor can purchase a single SKU item to hold in inventory and then the needed manifolds.Given the critical importance of Hydraulic Power Units in industries from agriculture to construction, heavy equipment, mobile and recreational vehicles, Submerged HPUs are bound to appeal to OEMs experiencing excessive service calls. By ensuring the motor and gear pump are protected within the oil reservoir from wet or humid environments, the result will be fewer repairs and greater equipment reliability.

It’s worthwhile to tweak the production process to decrease both the complexity and the overall expense of your project.Before diving into some tips, let's pinpoint the primary cost factors in injection molding:• Tooling costs, which encompass the design and machining of the mold.• Material costs, based on the amount of material and its price per kilogram.• Production costs, tied to how long the injection molding machine runs.For smaller batches, tooling has the greatest impact, contributing to roughly 50 to 70 percent of the total cost. Therefore, it's essential to plan in advance to accommodate your project's needs.Most molds are CNC machined from metals like aluminum or steel for durability. These molds can cost anywhere from $10,000 to $100,000. If you're producing thousands of parts, that investment is justified. However, for smaller batches, 3D printed molds have become quite popular owing to improvements in additive manufacturing.Here are some tips to help you optimize the cost of your injection molding project:1STICK TO THE STRAIGHT-PULL MOLDUsing side-action cores and other in-mold mechanisms can bump up tooling costs by 15% to 30%. This means you might face an extra tooling expense ranging from $1,000 to $1,500. To keep your production on budget, avoid using side-action cores and other mechanisms unless absolutely necessary.2REDESIGN THE INJECTION MOLDED PART TO AVOID UNDERCUTSUndercuts add to costs and complicate things, so it's always worth the effort to get rid of them where possible.3 MAKE THE INJECTION MOLDED PART SMALLERSmaller parts can be molded faster resulting in a higher production output, making the cost per part lower. Smaller parts also result in lower material costs and reduce the price of the mold.4 FIT MULTIPLE PARTS IN ONE MOLDUsing a single mold for multiple parts is standard practice. Typically, you can fit six to eight small identical parts in one mold, cutting down production time by roughly 80 percent. You can also place parts with varying shapes into the same mold, much like model airplane kits. This strategy significantly trims assembly costs. Sometimes, two assembly parts share the same main body.

This lets you use one mold for both parts, halving your tooling expenses.5AVOID SMALL DETAILSManufacturing a mold with fine details takes longer due to extended machining and finishing times. Text serves as a prime example, often demanding specialized techniques like electrical discharge machining (EDM), which can drive up costs.6USE LOWER-GRADE FINISHESHand-applying finishes to molds can be pricey, especially for high-grade finishes. If your part isn't meant for cosmetic purposes, it's best to skip the expensive high-grade finish. 7MINIMIZE THE PART VOLUME BY REDUCING WALL THICKNESSSlimming down the wall thickness of your part is a prime strategy to reduce its volume. This not only uses less material but also significantly speeds up the injection molding cycle. For instance, cutting the wall thickness from 3 to 2 millimeters can slash the cycle time by 50 to 75 percent. Why? Thinner walls allow the mold to fill faster. Even more crucial, thinner parts cool and set more rapidly. Consider that nearly half of the injection molding cycle is dedicated to letting the part solidify, with the machine on standby. However, it's essential to strike a balance. You don't want to compromise the part's rigidity, which could affect its mechanical performance. To maintain stiffness, consider adding ribs in strategic areas.CLOSING CONCERNSAlso, note that opting for 3D printed molds can drastically reduce mold expenses, bringing them down from thousands to just a few hundred dollars. However, this choice is most suitable for short runs where wear resistance isn't a primary concern. For high-volume production runs (10,000 to over 100,000 units), material and production costs eclipse the impact of tooling costs on the overall expense. In such scenarios, your focus should be to reduce both the volume of the part and the duration of the molding cycle.

As U.S. and European lawmakers tighten restrictions on toxic PFAS contaminants in water, utilities and businesses are working to safeguard drinking water supplies for communities. Often referred to as “forever chemicals,” PFAS are widely used, long lasting chemicals whose components break down slowly over time. Below, Snehal Desai, senior vice president and chief growth and innovation officer at Xylem, discusses how to address this challenge.MPT: Before we discuss potential solutions, let’s lay out the problem. What are PFAS and why are they a problem?SNEHAL DESAI: PFAS chemicals are human-made but have become widespread in some water sources across the country and can have potentially harmful effects on human and animal health. Estimates from the U.S. Environmental Protection Agency (EPA) show that one in eight public drinking water systems contain PFAS concentrations that exceed the maximum contaminant levels set out in their 2023 National Primary Drinking Water Regulation proposal.MPT: How can PFAS concentrations be addressed? Where are these plans being put into action?SNEHAL DESAI: Xylem is working with municipal and industrial customers to address this challenge, with more than eighty PFAS mitigation installations in the U.S. alone.For example, Stratmoor Hills Water District (SHWD), which oversees a combination of surface and groundwater sources in the foothills of Cheyenne Mountain in Southern Colorado Springs, has deployed selective ion exchange treatment aimed at countering the threat of PFOA and PFOS—two of the most commonly identifiable PFAS compounds of concern. Using selective single-use ion exchange technology, the utility has reduced contaminants to levels below compliance limits and mitigated water quality issues for its customers.MPT: Is there a way to tackle PFAS concentrations before they reach heightened levels?SNEHAL DESAI: In Maine, the Kennebunkport, Kennebunkport & Wells Water District (KKWWD) took a proactive approach when it detected PFAS in one of its system’s supply wells. KKWWD worked with Xylem to deploy a granular activated carbon system that has treated more than 200 million gallons of water to meet the utility’s drinking water treatment goals.Elsewhere in California, the Orange County Water District (OCWD) deployed over thirty liquid-phase media adsorption vessel systems to treat for PFAS, following a change in California law in 2020. The vessels were connected to existing drinking water wells to allow individual water districts to continue delivering drinking water in compliance for its more than 2.5 million customers.MPT: What have these different cases taught you about taking on these “forever chemicals”?SNEHAL DESAI: The experience of these early adopters demonstrates that with the right technology and expertise, utilities can meet treatment and compliance goals cost-effectively for their communities. 36 | FEBRUARY 2024 WWW.MPTMAG.COMMPTEFFICIENCY POINTEFFICIENCY POINTNOTHING LASTS FOREVERXylem’s Snehal Desai on PFAS treatment technologies to safeguard drinking water Snehal DesaiXylem is a global water technology provider helping our customers solve the world’s toughest water challenges across utility, industrial, commercial, and residential markets worldwide.
