Transition Control, which is found on the first page of the Field Setup Menu on the 5.7” PACE HMI’s, is a feature which suspends the work of the PID speed output block during a transition from VFD control to XL, (Across the line) operation of a main pump. This temporary suspension is important so that the PID output block will not attempt to adjust for sudden, but inevitable hydraulic changes during the transition from VFD Control to XL operation.
In some instances where the station controls include a shared soft start system and field hydraulic circumstances require a longer transition hold time, the factory set Transition Control Hold times may be too short. Try increasing these times from 4 to 7 seconds, in order to allow a smoother transition.

The US MOTORS® brand of Vertical Hollow Shaft motors (VHS), manufactured by Nidec Motor Corporation, are among the most innovative and trusted electric pump motors in use today. Many of the features we look for in VHS motors were first introduced in the HOLLOSHAFT® motor. From its genesis in 1922, the U.S. MOTORS brand continues to innovate. Here’s a brief timeline of their product line:
Innovation leadership doesn’t happen by accident. Nidec works closely with pump companies such as Xylem Flowtronex in Dallas, Texas, to fully understand our pump and motor product end-users needs and concerns, then develops products and processes to meet the industry demands. NMC also takes an active role in industry organizations such as the Hydraulic Institute to anticipate the challenges we face in an era of increased energy efficiency regulations. Their leadership role was recognized when the Hydraulic Institute awarded the 2015 Young Engineer of the Year to Patrick Hogg, Application Engineering Manager. With engineers like Patrick guiding vertical motor development, we trust that Nidec Motor Corporation will continue to provide industry-leading features in US MOTORS branded products.
At Nidec, rapid product delivery is at the top of the priority list. To ensure the company meets that goal, and in alignment to match our customers expedited product demands, they stock an expansive VHS motor inventory in multiple warehouse locations throughout the United States, with motor conversion centers in both, Southaven, Mississippi and Los Angeles, California. In these centers, factory technicians customize stock motors with only three working days lead-time.
Installation of US MOTORS
Instrumental to maintaining a smooth process flowfrom motor specification and order entry through product delivery, is Sales Account Manager, Dennis Mino, our local NMC rep in Dallas, Texas. Dennis works very closely with me to keep us up to date on new products and assists in quoting “Custom-built” motors. He provides a level of service that only a local presence can provide.
Nidec’s Product Service Manager, Bob Wiesler, leads a team that delivers engineering support direct to pump manufacturers and coordinates motor repairs through more than 500 Authorized Repair Centers in the U.S. and Canada.

Goulds Water Technology offers Aquavar® e-ABII booster package with HSC multi-stage pump hydraulics
115v or 230v three-phase motor powers the lead-free booster package, reduces energy demand up to 50 percent
Auburn, N.Y. — April 19, 2017 — Goulds Water Technology (GWT), a Xylem brand, has expanded its Aquavar® e-ABII booster package line for residential and commercial applications to include a NSF-certified lead-free package that operates with HSC multi-stage pump hydraulics.
The e-ABII booster package with HSC multi-stage pump hydraulics comes standard with a pressure transducer, cable, controller and the choice of 115v or 230v electrical supply options for seamless installation. To offset any poor system pressure concerns, a performance of 40 gallons per minute (GPM), with a pressure boost range to 90 psi can be achieved.
The Aquavar e-ABII booster package with HSC multi-stage pump hydraulics is designed for municipal water district customers with low water pressure, or those customers drawing water from a storage tank who want continuous water pressure, even when demand is high. As water use increases at the end-user level, the GWT Aquavar e-ABII changes pump speed to ensure the municipal line pressure remains constant. This eliminates the need for large supply tanks, and saves up to 50 percent of the energy required by a full-speed pump.
The Aquavar e-ABII booster package with HSC multi-stage pump hydraulics is available in one, two and three horsepower (HP). One and two HP packages come standard with a GWT Aquavar e-ABII drive and tank, and are wired by GWT. Three HP packages are supplied with a GWT Aquavar drive.

Whether used to remove cosmetics, clean a baby or wipe food and debris from the kitchen counter, a growing number of consumers are purchasing flushable wet wipes for their household needs. In fact, The Atlantic reported personal wet wipe sales reached an estimated $2.2 billion last year, and Euromonitor International’s market tracker predicts 3-percent growth in sales volume of wet wipes from 2014 to 2019.
Sales of flushable wipes have increased due to their convenience. But this convenience can come at a high cost as demonstrated in news reports about the detrimental effects these wipes can have on plumbing systems. Because of this risk, it’s important to understand how these flushable wipes can cause system destruction and what pumps should be installed to better handle them.
The waste being flushed through the modern wastewater stream today is very different than in the past, with flushable wet wipes as a prime example. Unlike toilet paper, wipes don’t disintegrate easily or quickly and can clog sewage treatment equipment and home septic systems. Clogging can occur when a number of wipes get stuck in a pump, or if debris builds up on the flushable wet wipes that are already stuck in the system. Because of these potential harmful effects, flushable wipes need to be removed and dumped, often at the municipal level. They are removed using a large filter screen that is lifted by a hoist, or in a settling area that separates and removes the wipes by a front- end loader since wipes don’t break down within the time frames for which sewage treatment plants are designed.
The term “flushable” itself is somewhat misleading. Many consumers believe that when a wipe is labeled flushable it is safe to flush it down the toilet. If it weren’t for the recent news coverage, many people would not know that these wipes actually become clogging material as they travel through a pumping system — and costly material at that. According to a 2015 New York Times article, New York City, which runs the largest sewer system in the United States, spent more than $18 million over five years to repair equipment problems because cloth-like material, such as flushable wipes, didn’t disintegrate.
To address challenges presented by flushable wipes, the industry is adapting and introducing products, including grinder pumps and vortex impellers that are designed to help alleviate system damage.
A grinder pump is a wastewater transportation device that helps filter household waste, like personal wet wipes, to the larger sewer system. Waste from a water- using household appliance — toilets, sinks, etc. — flows through a home’s pipes into a grinder pump’s holding tank. Once the wastewater inside the holding tank reaches a certain level, the grinder pump will turn on, cut the waste materials into tiny bits and pump the slurry to the central sewage system or septic tank.
Many grinder pumps, like Xylem’s RGS2012 Residential Grinder Pump, are designed for residential and commercial sewers where flushable wet wipes are present in the stream. Flushable wipes can go through toilet plumbing, but not necessarily the entire sewage system. This is where a grinder pump takes over. It cuts the wipes into tiny pieces, which are then passed down the piping network before being discharged at a collection point. Xylem’s RGS2012 Residential Grinder Pump is designed for continuous use and is capable of grinding domestic sewage in high head sewage applications.
Evolving grinder pump technology is leading to the use of alternative pump materials in the manufacturing of pumps. Traditionally, grinder pumps were constructed of cast iron and filled with oil. Manufacturers like Xylem, are looking at other high- efficiency casings that are air filled because it takes less energy to spin the motor rotor in air than it does in oil.
Another industry trend is the redesign of the cutter technology using multilobe axial cutter wheels. The new design enables grinder pumps to process nontraditional amounts and sizes of waste discharge because the multilobe axial cutter wheels chop the waste materials into extremely small pieces.
Vortex impellers are designed so the waste stream material traveling through the impeller does not need to touch it in order to pass. This helps to prevent materials, like flushable wipes, from collecting on the impeller and eventually clogging the system.
For example, if a pump has a 2-inch solids handling requirement, which is a common residential wastewater specification, the 2-inch sphere does not need to touch the impeller when it passes through the volute — the curved funnel that enlarges as it approaches the discharge port – of the vortex pump. If the waste material traveling through the pump is stringy, stranded or even cloth-like, a vortex impeller helps prevent the slurry from forming a twisted mess that would otherwise bind or clog the pump.
It is important to note that grinder pumps and vortex impellers can help avert clogs, but they are not a panacea. They are not designed to remove the wipes from the sewer system, and, on occasion, do not break down the wipes enough to enable them to pass through the pump. If a pumping system becomes clogged, the only way to fix the plumbing issue is to remove the wipes from the system.

The “receiver” or “tank” in a Domestic® Pump steam condensate handling unit should be of the proper material and size for the application, following industry best practices and ASHRAE recommendations. Condensate collection tanks generally come in two types of material – cast iron or steel. Both meet the highest industry standards and provide years of service. The main difference is that cast iron tanks have more than 2 percent carbon content in the iron-carbon alloy.
Close-grained cast iron is the most-used material for domestic receivers. Features include high quality, durability, corrosion resistance, heat retention, leak-tightness, machinability—and a 20-year warranty against corrosion. It is the standard for the majority of our build-to-order and stock products. The average life of a cast iron tank is 25-30 years.
Cast iron’s machinability lets us process all the receiver’s operational openings – for the condensate inlet, the pump connections, the vent, overflow, drain, gauges, switches, make-up water, etc. However, steel offers even greater flexibility for customizing tanks. The more machinable steel receivers can be easily modified for the customer’s specific application.
Black steel is a budget option for rectangular cast iron receivers, and standard for cylindrical tanks. Cylindrical receivers are dish-headed and reach up to 1,697 gallons in volume, compared to a cast iron tank’s 250-gallon maximum. Steel tanks cannot equal cast iron’s heat retention or corrosion resistance; their typical warranty is 12 months from date of installation or 18 months from shipment.
We can increase corrosion resistance for cylindrical black steel receivers with optional galvanized, epoxy-lined or stainless steel tanks. We can also insert an optional magnesium anode corrosion inhibitor, which attracts the corrosion process and extends the steel tank’s life.
Good care is important to keep the receiver in shape and provide a safe environment. Note that in Domestic Pump units, receivers must not be pressurized, and boiler feed chemicals should not be fed directly or ahead of the tank. You can easily recognize Domestic units by the gray paint – a water-based, environment-friendly enamel that coats all our units’ composites (tanks, pumps, etc).

1. Q. How do I maintain Low Water Cut-Offs?
Find detailed maintenance instructions for McDonnell & Miller low water cut-offs in the installation and operating instruction manual (IOM) that ships with the product. You can also get the IOMs online at www.mcdonnellmiller.com.
Here’s a brief summary of required maintenance. Please refer to the appropriate IOM for detailed instructions.
Probe-Style Low Water Cut-Offs
• Test annually
• Inspect self-cleaning probe every 5 years (annually if not self-cleaning)
• Replace probe every 10 years
• Replace complete control every 15 years
Float-Operated Mechanical Controls
• Hot water boilers: blow down quarterly
• Steam boilers below 15 PSI: blow down weekly
• Steam boilers above 15 PSI: blow down daily
• Disassemble and inspect annually – including float chamber and equalizing piping
• Replace head mechanism every 5 years
• Replace control every 15 years
A Special Note on Commercial Steam Boilers
The National Board of Boiler and Pressure Vessel Inspectors (ASME) recommends daily blow-down and testing of all low water cut-offs on commercial steam boilers. Many local codes require this.
2. Q. I installed a new electronic water feeder – why is my boiler flooding?
A. Common causes of flooding include:
• Feeder pump not balanced to boiler requirements
• Faulty swing-check in return header
• Plugged equalizing pipe connection
• Leaking tankless hot water coil in boiler
• Attendant over-filling boiler through the hand bypass valve
• Dirty water resulting in priming and carryover
• Too small a difference between level of dry return and boiler water level
• City water pressure above 150 lbs. (May need pressure-reducing valve in feed line)
Faulty installation can cause flooding. Remember that the closing level of make-up feeders on heating boilers should be set 2″ to 2 1/2″ below the manufacturer’s recommended boiler water line. This lets the system return balance varying steaming rates without adding make-up.
B. Always troubleshoot the whole system, not just one control. Boilers often flood because of a malfunctioning low water cutoff or clogged return pipes. To determine if the feeder is shutting down completely, do a “broken union test.”
• Make sure the boiler water level is above the feeder’s closing level.
• Close the outlet valve in the feed pipe – running from the feeder to the boiler.
• Uncouple (break) the union between feeder and boiler.
– Lower the boiler water level to observe water flow through the feeder.
– Raise water back to the shutoff level to verify that no water flows out. If water does
come out of the union, the water feeder is leaking and needs to be repaired or replaced.
– Open the outlet valve to verify there is a steady flow of water coming back from the boiler.
If not, check the feed line for lime or scale, which can hold the feeder open due to back pressure.
• Check for leakage past the bypass valve by opening the union below the bypass valve.
– If there is a leak, repair or replace the bypass valve.
Broken Union Test
3. Q. Why won’t the valve shut off drip-tight?
Do the broken union test to be sure the valve really is leaking. Often the valve is not leaking, and the cause of the flooded boiler is in the system.
If the valve is leaking, your best option is to replace it—especially if it’s an old-style pilot action valve or metal-to-metal valve. Bring it up to date with a cartridge valve. Initially, you’ll have to replace the whole valve (models SA47-101-102 & SA51-101-102…pre-August 1995.) After that, you’ll need to replace only the cartridge if the valve fails to shut off drip-tight.

Bell & Gossett launches ESP-Systemwize system selection tool
Best-in-class online program enables industry professionals to specify complete pump systems
MORTON GROVE, ILL. — June 13, 2017 — Xylem’s Bell & Gossett brand has introduced ESP-Systemwize TM, the industry’s first online selection tool that provides HVAC and plumbing system designers the ability to choose all system components within a single integrated tool to ensure the most efficient hydronic system design.
“Proper system design is critical to minimizing life-cycle costs and reducing a system’s power consumption. We’re seeing a trend where building owners, facility managers and specifying engineers are increasingly putting holistic system performance at the top of their lists when it comes to commercial buildings — whether that’s retrofitting or new construction,” said Mark Handzel, Vice President, Product Regulatory Affairs, & Director, HVAC/Commercial Building Services Americas, Xylem Applied Water Systems. “Bell & Gossett’s expansive portfolio, applications expertise and hydronic systems knowledge has been incorporated into ESP-Systemwize, resulting in an intuitive, easy-to-use tool for selecting highly efficient pumps and compatible system accessories.”
ESP-Systemwize is the evolution of Bell & Gossett’s ESP-Plus Online, integrating the most popular aspects of the previous program while adding new user-friendly features to specify efficient pump systems.
The system selection tool includes Bell & Gossett’s Part Load Efficiency Value (PLEV) selection criteria, a calculation that represents the efficiency of the pump at partial flow rates. Flow requirements fluctuate constantly based on the heating and cooling needs of a building at any given time. However, with the traditional pump selection approach, industry professionals select pumps at 100 percent load conditions, although a pump only operates there 1 percent of the time.
“When combining highly efficient pumps with selections based on PLEV, system designers can maximize operational performance while realizing energy and cost savings,” Handzel said.
To further ensure efficient system selection, ESP-Systemwize guides industry professionals through the specification process by providing side-by-side product comparisons, an express select button that helps quickly narrow down a pump search, and an active warning system that alerts users of potential selection problems. ESP-Systemwize is also searchable by groups of products — a click of the performance button analyzes a pump’s multiple speeds in real time and the workplace tab offers additional product data.
The system selection tool allows industry professionals to specify pumps, suction diffusers, triple duty valves, air and dirt separators, expansion tanks, heat exchangers, pressure independent control valves and replacement parts.
“Now, more than ever, industry professionals are turning to HVAC manufacturers to answer their questions quickly and thoroughly throughout the system specification process,” Handzel said. “When someone clicks on the help button to submit comments and questions, they will be addressed in real time. If a very technical response is required, ESP-Systemwize will alert product experts to respond.”
Another feature of ESP-Systemwize that helps industry professionals with the pump selection process is the option to create a customized project schedule, share it with a manufacturer’s representative in their area, and edit it, enabling the management of the entire system selection process in a single project schedule. Engineers and system designers can also generate submittals and download other technical documentation for information on proper installation and applications of the products they selected.
ESP-Systemwize will be updated regularly with new features and capabilities to maintain its status as the most comprehensive system selection software available today. To learn more about the ESP-Systemwize system selection tool, please visit www.esp-systemwize.com or watch the launch video.

Motor design is key to the performance and service life of a pump. But determining the size of the motor required to drive the pump is something people often struggle with. This is especially true of wastewater submersible pumps. It’s a common assumption that you can use motor nameplate information at face value. That applies to some, but not all nameplate data. A primary example is service factor (SF).
Generally, service factor is the measurement used to determine the peak performance at which a pump motor can operate. The National Electrical Manufacturers Association (NEMA) defines service factor simply as a multiplier that indicates the amount of additional load a motor can handle above its nameplate horsepower. The service factor industry standard for a totally enclosed motor is 1.0.
To determine the service factor horsepower of a motor, multiply the nameplate horsepower by the service factor. For example, if a 1 HP motor has a service factor of 1.5, the motor’s service factor maximum horsepower is:
(1 HP) x (1.5 SF) = 1.5 HP
However, when sizing submersible wastewater pump motors, horsepower service factor, which applies only to the motor, is not a primary consideration. While service factor can be used to handle intermittent or occasional overloads, designers cannot rely on the service factor capability to carry the load on a continuous basis. Doing so will likely result in reduced motor speed, and the reduced life and efficiency of the pump.
Designing for continuous duty
When sizing a submersible wastewater pump motor, it’s important to consider whether the pump will ever be required to operate at a flow rate higher than the design point. If, for example, the pump was allowed to operate at the end of the head capacity curve, the actual horsepower requirement may exceed the design point selected motor horsepower and overload the motor. For this reason, it is common practice to size the motor not for the design point, but for the end of the curve or maximum horsepower requirements.
In the example above, a 7.5 HP motor would adequately power the pump at a design point of 120 GPM at 150 feet; however, looking at the end of the curve, brake horsepower requirements call for a 10 HP motor.
It’s also important to note that submersible wastewater pumps follow Affinity Laws – the mathematic relationships that allow for the estimation of changes in pump performance as a result of a change in one of the basic pump parameters. If either the speed or impeller diameter of a pump changes, you can approximate the resulting performance change using the following:
Pursuing peak pump performance
Taking all of these factors into account, the NOL Horsepower (or non-overloading brake horsepower) is a more accurate criterion when it comes to sizing the motor for a submersible pump. The NOL Horsepower is the maximum power value calculated in order to handle the maximum power demanded by the pump at any point along the curve. NOL Horsepower represents the amount of real horsepower going to the pump, not just the horsepower used by the motor.
Although not typically listed as part of the operational information on the pump nameplate, NOL Horsepower is one of the key factors confirmed during pump performance testing. If motors overload at any point on the published curves during testing, listing agencies like UL and CSA will not award product certification to the motor vendor.
While the factors used to size a motor that will operate anywhere on the pump curve may not be those typically used as defined for standard NEMA motors, there are advantages. Selecting a pump/motor combination that will function under all possible operating conditions will result in higher efficiency, longer service life and uninterrupted performance — even in a continuous duty application.
