Polypipe and Compression Fittings

JMI Pump Systems stocks polypipe from Polyethylene Technology Inc., based in Lakeville, Minnesota, which offers Copper Tube Size (CTS) and Iron Pipe Size (IPS) polyethylene (PE) pipe in a variety of sizes that meet NSF/ANSI Standards 14 & 61. All stacked polypipe is also certified to NSF/ANSI 372 requirements for “lead-free” plumbing.

The coil ends are heat-sealed and pressurized to ensure no leaks. Other key features include permanently indented print; color coded and bar-coded labels; and coils bundled and wrapped in poly stretch wrap.

Benefits of Polypipe

Polypipe, which is crack resistant and not affected by temperature fluctuations, has exceptional strength and endurance, impervious to abrasion wear or damage from fatigue. It also is used where there may be a possible concern over pipes corroding. It won’t rot, produce odors, or damage the taste of liquid. Lightweight and flexible, it’s ideal for hard-to-reach spots and it can stretch under pressure. In applications where there are multiple turns, you can connect the copper pipe to PE pipe to finish an installation.

Polyethylene CTS and IPS pipe, which is specific to plumbing and potable water systems, is very resistant to damage, yet extremely flexible. Suitable for industrial applications and featuring an extensive range of wall thickness options, it is manufactured with high performance PE4710 resin that provides maximum performance benefits. This higher density resin increases tensile strength, stiffness, and chemical resistance. Plus, the pipe made from this resin is heat fused on each end for a leak-free seal. Both the CTS and IPS PE pipe are available with a working pressure rating of up to 250 psi. JMI currently stocks CTS pipe in blue, while it has IPS pipe in black.

Compression Fittings

In addition to offering polypipe, JMI also stocks Philmac compression fittings from IPEX. Featuring the unique Slide and Tighten™ technique, Philmac 3G compression fittings for CTS and IPS pipes make installation simple. In addition, they offer a high integrity 230 psi rated connection and have no corrosion or lead risk, and yes, they are approved to be buried. Connections are available for CTS from ¾- to 2-inches, while connections for IPS are from ½- to 1½-inches. The connections also meet NSF/ANSI Standards 61 for cold water only use.

Also from Philmac, JMI has available Universal Transition Coupling (UTC), which again features Slide and Tighten™ technology. The UTC, CSA and NSF 61 approved for potable water use, is rated to 180 psi. It accommodates a range of different outside diameters across most pipe materials, including PVC, copper, galvanized iron, ABS, lead, stainless steel, and steel, plus UTC can be used to join two different pipe materials together.

No pipe preparation is needed and no force is required to push the pipe past the seal. This means faster and easier installation because the fitting seals on the outside of the pipe. Simply insert the pipe into the fitting until the first point of resistance is felt and then tighten the nut. The size of the fitting has been kept to a minimum, making the fitting ideal for use in confined areas.

Each fitting is pre-assembled and ready to use so there’s no need to disassemble the fittings or prepare the pipe. And what’s more, there is no need for special tools or solvent cement. Simply cut the PE pipe square and insert it into the fitting until you feel the first point of resistance and then tighten the nut to the flange. Just slide and tighten and the job’s done! Typically, only two turns are needed to tighten the nut. The body flange on the 3G® compression fitting acts as a visual stop to indicate when the nut is tightened. There is no benefit in further tightening the nut. And, YES, they can be buried.

Product Focus: Seamless, One-Piece, Low Profile Septic Tanks

JMI has expanded its line of products to the pump and septic installer with the Norwesco line of low-profile tanks, pump chambers, and septic tank risers.

Norwesco polyethylene Low Profile Septic Tanks are manufactured using a proprietary state-of-the-art rotational molding process, ensuring uniform tank wall thickness and maximum strength.

The low-profile tanks also provide several advantages when compared to septic tanks made of traditional materials. Their lighter weight makes them easier to transport and install, and the combination of the low profile and ease of installation make the new tanks an ideal choice for all installation sites. They require no special backfill or filling with water during installation, saving significant time. Because the tanks are seamless, they is no assembly or leakage testing, saving more time and effort during installation.

Additionally, polyethylene is unaffected by soil chemicals and by the chemicals and gases present in sewage. This means the tanks will not rust, corrode, or require additional coatings as other tanks do.

Our stock tank sizes range from 500 gallons with a single compartment and 750 to 1,500 gallons with single or double compartments. Norwesco tanks, which are available up to 10,000 gallons, are suitable for use as a septic or pump tank and may also be used for non-potable water.

Norwesco also offers low-profile cistern tanks for instances when drinking water must be hauled in or if a well does not meet consumption needs. Manufactured using resins that meet FDA specifications to ensure safe storage of potable water, where applicable, the cisterns have been certified under ANSI/NSF Standard 61.

Pump Chambers and Risers

Norwesco offers a full line of polyethylene plastic pump chambers (tanks), risers, and lids.

Pump chambers are required when gravity prevents the wastewater from being pumped due to the site having a higher-water level. The pump chamber will distribute effluent wastewater and sewage to the main sewage system or the septic tank system.

Norwesco spherical pump tanks are designed to be used as a holding tank or pump tank with a capacity range of 200-525 gallons and are structurally sound in the ground when empty. These tanks are furnished with manhole covers and include a molded-in elevated pump stand on the bottom of the tank.

Manhole extensions and lid-riser combinations are available to bring tank access to grade and to meet code specifications. Because they are polyethylene, they are strong, durable, lightweight, and easy to handle. The riser connects to the septic tank and the pump-out opening or access port. The riser reduces labor time as all that is required is to run a pump hose into it to access the tank. That means no more digging up the ground and having to rebury the tank.

Whatever your needs for tanks or pumps, no matter your pumping application, JMI Pump Systems has a large selection from which to choose. Plus, you can depend on our expert staff to provide “No Problem” Service, helping to determine the right solution for your situation.

Understanding Three-Phase Motors

Three-phase motors are commonly used in large pump applications, such as those affiliated with agriculture and manufacturing operations, as opposed to the single-phase motors typically found in residential and light-non-industrial applications.

Single phase power is not recommended for use on motors greater than 5HP because a single-phase motor draws significantly higher current than a three-phase motor of the same horsepower rating. Based on cost, single-phase motors are less efficient compared to three-phase, increasing operational costs.

For larger applications requiring efficiency and consistency, a three-phase motor is the best option. The advantages to using a three-phase motor include:

  • Energy savings, as three-phase motors use up to 90% less power to do the same work as a single-phase motor and can turn over the same amount of water at a lower pump speed. Three-phase motors can transmit three times the amount of power of a single source, while using only 1.5 times the amount of conducting wires.
  • Three-phase motors provide smooth, balanced power. The consistency in the supply of power is due to three identical overlapping wave cycles, which are evenly spaced 120 degrees apart, so the supplied power remains constant.
  • The constant power potential is not only preferable, but necessary in many situations where the business, farm, or factory needs and depends on consistent power.
  • Three-phase motors can run at a higher voltage with thinner gauge wire due to the lower amperage used. The lower pump speed and reduced friction also produces less stress and cooler temperatures for other components. Plus, there is less vibration, reducing stress on pipes.
  • A three-phase motor water pump has a simple design and smaller body size, also resulting in cost savings. Their reliability and longer life span also extends the pump replacement interval.

Important Installation Note — Check the Pump’s Rotation

One critical factor that must be adhered to after the power is supplied and before the pump is lowered into the basin is to check the pump’s rotation so the performance desired is achieved and no damage occurs. Not to mention the time and energy required to reverse the issue after the fact.

Three-phase power is easily wired to run a pump in reverse; the motor can run forward or backwards (clockwise and counter-clockwise). Even with running backwards (or in the wrong direction), the pump will still function – and pump water, but this type of misuse will eventually cause pump/motor failure.

Three-phase pumps have stickers, engravings, or casted directional arrows indicating the rotation direction when looking at the entire pump/motor assembly. To test, give the pump a quick bump of power and check that the impeller is rotating in the same direction as the arrow. If a three-phase motor rotates in the wrong direction, you can swap any two leads to change the desired direction. Just make sure you test the motor again before installing and note the terminal/wire color combination as well.

With installations where more than one pump is being installed, rotation must be checked on each pump. Do not assume the color coded wires from the pump are the same – they typically are but not always.

Duplex Pumps – How They Work and Where You Use Them

In Wisconsin, duplex pump systems are required by code in commercial buildings when there are three or more water closets or more than 20DFU’s draining into a sewage basin. Duplex systems are also used in large volume stormwater pump stations, as well as when redundancy is desired.

The duplex pump system is one of the most common configurations in a pump station design, providing efficiency and redundancy. The duplex design is often referred to as lead/lag systems because the standby pump (lag) is activated as demand exceeds the capacity of the lead pump or if the lead pump were simply to fail.

For example, a typical design requirement for pumping wastewater is that a single pump will discharge more than the peak inflow. In wastewater and sewer applications, the peak flow needs to be able to be pumped by the lift station even if it never occurs.

An alternator controlling the duplex system allows the pumps to cycle between starts, resulting in even wear on the pumps. If one pump needs to be serviced, the system remains automatic by utilizing the lag pump.

The alternating control panel is typically operated by three control float switches: stop float, lead float, and lag/alarm float. There are some systems that do use four floats, separating the lag and the alarm function.

The stop float is the float that turns off whichever pump was called on to run. The lead float is the float that runs whichever pump happens to be called on for at that cycle. In a three float system, the third float is the lag/alarm float. If the liquid reaches this float, the lag pump will turn on and the alarm will sound, warning there is a system problem. At this time, the pump(s) will continue to run until the stop float is lowered to the stop position. The next time the lead float is triggered, the other pumps will assume the “lead” role.

The alarm must be installed on a separate electrical circuit, separate from the circuits feeding the pumps. If one breaker is being used for the incoming pump power for both pumps, it needs to be sized for the possibility of both pumps starting and running at the same time. It is highly recommended to have separate circuits for both pumps and the alarm, totaling three circuits.

The controls can be purpose-built, a PLC or programable I/O. PLC controls can be enhanced with an HMI (Human Machine Interface) Touch Display to directly interact with sensors, valves, pumps, motors, and more.

JMI Pump Systems also offers an assortment of steel, stainless steel, and custom PVC cover options for pump basins as well as packaged systems with controls. The standard covers we provide will typically maintain separate access for pumps and floats for improved serviceability.

JMI Pump Systems professionals are able to assist you with finding the best duplex system for your application. For more information, Your Partners in Pumping are available at 262-253-1353 or

Adding a Water Booster Pump to Increase Pressure

Water booster pumps help increase the pressure and volume of water to faucets, showerheads, toilets, hose bibs, and the like in both residential and commercial (particularly high-rise) applications.

There are several reasons for low-water pressure. Gravity is one because the higher the level at which the water needs to be supplied, the lower the water pressure. Distance from the water source and the diameter of the water pipe also affects pressure. If a home or building is at the end of the water supply line, the pressure will likely be lower by the time it reaches the structure. Low water flow can also result from low pressure water from the local water plant. Plus, additional water treatment systems or other water-using devices will reduce water pressure, such as iron curtains, water softeners, and R/O systems.

Although a water booster pump will increase pressure, keep in mind that as the pressure required to move water increases, the volume actually does not increase. As a matter of fact, the opposite occurs. Think of it as water running from your hose. If you put your thumb over the nozzle, the water comes out at a higher pressure, but the flow rate is restricted. Booster pumps have a similar end result – as pressure increases, flow decreases.

Which booster pump you need depends on the amount of water used, the desired discharge pressure, and the application of the water source. Are you sizing for a single-story home, multiple level apartment complex, or a very tall building? Is the water from a tank, lake, pond, or municipal water supply?

The pump professionals at JMI Pump Systems can help you select just the right size pump for your application. We particularly like the options Franklin Electric offers.

For example, their Subdrive Inline 1100 works in the following applications: boosted and constant water pressure from water storage/cistern systems; for homes in both private and municipal applications; sprinkler systems; farming and commercial wash down systems; and general pressure boosting.

The simplex packaged system includes pump, motor, drive, and pressure switch. It features a small and compact design to fit into small areas, even between floor joists, and is one of the only boosters with a zero foot print. Multiple mounting configurations allow for the unit to be installed where needed, whether horizontal, vertical, or upside down. The pump provides up to 40 gpm and/or up to an additional 60 psi.

The Inline 1100 SpecPak connects to nearly any commercial, industrial, or multi-residential plumbing configuration. Thanks to its modular form, it offers the flexibility to add pump models to the base package so the system can grow to accommodate new or unexpected water demands.

The pump itself is a quiet, all-in-one constant water pressure system. As water volume needs increase, the pump instantly accelerates to the proper speed to ensure the water pressure stays constant throughout the application.

The 1100 SpecPak is offered in simplex through quadplex, providing maximum flow rates from 40 to 160 gpm, and up an additional 60 psi. The system comes prepackaged and ready for installation virtually anywhere. Simply hook up piping, add power, and it’s ready to use.

JMI also provides the traditional floor mounted boost packages build to your required specifications. As with all our pump products and accessories, the JMI Pump Systems professional staff can help you determine the correct pump and controls for your pump application.

What Other Things to Consider When Selecting a Pump

When selecting a pump, there are many criteria. But the most important consideration is selecting the pump to meet system requirements, not the other way around. What is meant by that is “tried and tested” pumps may not be the most effective as the application parameters may have changed – or even the pump. The optimal approach is to assess the entire system to improve performance, efficiency, and reliability.

When choosing a pump, consider the Total Cost of Ownership (TCO). You might think the actual pump purchase is an important element of TCO, but in fact, the initial cost of the pump accounts for only 10% of the TCO, while energy consumption accounts for a whopping 65%. Other TCO components include:

  • Installation and commissioning costs (including training)
  • Energy costs (predicted cost for system operation, including pump driver, controls, and any auxiliary services)
  • Operation costs (labor cost of normal system supervision)
  • Maintenance and repair costs (routine and predicted repairs)
  • Downtime costs (loss of production)
  • Environmental costs (contamination from pumped liquid and auxiliary equipment)
  • Removal and disposal costs

So, while initial cost needs to be considered, you see there are many more factors in the TCO. Most importantly for specifiers or purchasing agents is to overlook the initial cost and buy a pump system that will work best for the application, handle the materials or volume, manage the flow of energy, and ensure reliability. An incorrect purchase can result in more money spent over time on repairs, poor energy efficiency, or lost production potential.

Energy Efficiency

The energy consumption required for any system depends on the flow rate of the entire system, including the pressure (head) and how often the pumps are operating. Some pumps run all the time, whether the process needs all that flow or not. When systems divert flow, operators are paying for power they are not using productively.

One way to reduce the energy consumption is by utilizing a Variable Frequency Drive (VFD), which can increase or decrease flow as needed. You can purchase a VFD that has the pump performance programmed in by the factory or retrofit existing pumps. Retrofitting requires that you have the space to install the VFD near the pump. In addition, installing instrumentation and connecting it as well as programming creates opportunities for error.

Another solution to offset energy costs is to use a bank of large and small pumps and stage them to turn on and off to meet demand.

Tip: Pumps that have an HI (Hydraulics Institute) Energy Rating Label will increase the savings.

Product selection

Consider the pump’s footprint — Frame Mounted vs. Close Coupled vs. Inline

How much available space and the pump’s footprint are factors to consider in the selection process.

Frame mounted pumps include a bearing housing to prolong the life of the bearings and allows for continuous operation with high radial and thrust loads. Typically used for larger applications where power ratings range from 20 hp to 200 hp, frame mounted pumps don’t need custom motors, giving you more choices to select a motor that meets the needs of your application.

Close coupled pumps occupy a smaller footprint and have only one set of bearings inside the motor casing. Because they do not need couplings, as the motor is directly mounted to the pump on a single shaft, they are also typically less expensive than frame mounted. However, the motor bearing must handle the axial and radial loads of the applications, which limits the size and power of the motor used. Close coupled pumps may be limited to 100 hp to 150 hp but offer space savings of 20%.

Inline pumps can dramatically reduce the footprint. Flow enters and exits on a single axis, requiring minimal floor space. For example, inline pumps can occupy a third of the floor space compared to a typical frame-mounted pump. Keep in mind that an inline pump also requires vertical space because they typically have a vertical motor above the pump.

Flow Requirements and Fluid Properties

When choosing a pump, fluid properties must be considered: density, viscosity, solids content, and temperature. Understanding fluid properties are critical to avoid failure or the need for continuous and costly maintenance. Key considerations include:

Acidity/alkalinity and chemical composition. Corrosive and acidic fluids can degrade pumps and should be considered when selecting pump materials.

Operating temperature. Pump materials and expansion, mechanical seal components, and packing materials need to be considered with pumped fluids that are hotter than 200°F.

Solid’s concentrations/particle sizes. When pumping abrasive liquids such as industrial slurries, selecting a pump that will not clog or fail prematurely depends on particle size, hardness, and the volumetric percentage of solids.

Specific gravity. The fluid specific gravity is the ratio of the fluid density to that of water under specified conditions. Specific gravity affects the energy required to lift and move the fluid and must be considered when determining pump power requirements.

Vapor pressure. A fluid’s vapor pressure is the force per unit area that a fluid exerts to change phase from a liquid to a vapor and depends on the fluid’s chemical and physical properties. Proper consideration of the fluid’s vapor pressure will help to minimize the risk of cavitation.

Viscosity. The viscosity of a fluid is a measure of its resistance to motion. Since kinematic viscosity normally varies directly with temperature, the pumping system designer must know the viscosity of the fluid at the lowest anticipated pumping temperature. High viscosity fluids result in reduced centrifugal pump performance and increased power requirements. It is particularly important to consider pump suction-side line losses when pumping viscous fluids.

The Flow Rate Factor

The flow rate is determined by total volume and the time to move the fluid through the casing and out to the desired location or piping system.

For example, with centrifugal pumps, the flow varies with changing pressure. These pumps impart momentum to the fluid by rotating impellers that are immersed in the fluid. The momentum produces an increase in pressure and when pressure is created, flow results.

When a system includes a centrifugal pump, an important design issue is matching the head loss-flow characteristic with the pump so that it operates at or close to the point of its maximum efficiency. When fluids of higher viscosity move through the system, the pump’s efficiency with decrease in head and flow.

On the other hand, a positive displacement pump can handle many applications that include viscous products. They can operate at high pressure and relatively low flow more efficiently. However, they are less able to handle low viscosity rates than centrifugal pumps.

These are many nuances to choosing the correct pump, with these listed being just a few to keep in mind. So, which pump to choose? That’s where the JMI Pump Systems team can help.

Sump Pump Alarms Are an Essential Add-On

In our last blog, we talked about the importance of battery back up pumps and some helpful accessories, including switches and alarms. In this blog, we will go into more detail about the importance of sump pump alarms as well as the alarms JMI Pump Systems offers.

Having a sump pump alarm is critical to alert end users about high water levels, power outages, and sump pump failure. Like a smoke detector, the alarm emits a high-pitched sound that can be heard throughout the house. Without an alarm, unchecked water invasion can result in costly repairs that can be in the thousands of dollars.

While a basic alarm will alert the end user in house, what happens if there is no one around to hear it. That’s where Wi-Fi alarms come into play. Wi-Fi alarms will alert you no matter where you are via a phone call, text, or email.

Battery backup sump pumps and alarm systems are the first line of defense against the extensive and expensive damage caused by basement flooding.

Ultimately, you want an alarm that alerts you no matter where you are, sends messages when the power goes out, and sends messages directly to your mobile device, so you can take immediate action. Here is a sampling of sump pump alarms we offer.

SJE Rhombus Xpert Alert™ Indoor Alarm System

This alarm helps protect homes from potentially costly damage due to flooding, pump failure, or freezing pipes.

When the tank level rises, the high-water float activates the alarm (audible and visual) to alert the homeowner of potentially threatening liquid level conditions.

The Xpert Alert™ also monitors low temperature conditions. When the temperature drops below 40°F (4°C), the low temperature indicator LED turns from green to red and the alarm sounds to alert the homeowner of the condition. This function can be disabled in cold climates.

In addition, the Xpert Alert™ includes auxiliary contacts for attachment of remote devices and has an automatic alarm reset. The switching mechanism operates on low voltage and is isolated from the power line to reduce the possibility of shock. The complete package includes a standard SJE MilliAmpMaster™ control switch.

The Xpert Alert™ is CSA Certified and covered by SJE Rhombus’ five-year limited warranty.

Most importantly, the Xpert Alert® indoor alarm system with Wi-Fi connectivity monitors and reports two separate alarm conditions for sump pump basins, lift pump chambers, holding tanks, sewage, agricultural and other water applications. The system monitors and reports any residential alarm condition by notifying locally (audible and visual) and remotely (SMS text message and/or email) over a Wi-Fi or Ethernet network to a smartphone, tablet, or computer. You can even include your plumber on the list of people to receive an alert.

No cellular connection is needed (no monthly fees), but it does require the homeowner to have a reliable Wi-Fi network and connection to the internet.

Compact NEMA 1 rated indoor enclosure is designed for easy installation.

Tank Alarm and Sump Advisor from Alderon

Alderon’s VersAlarm tank alarm can be used in applications such as septic tanks, sumps, holding tanks, pump chambers, water tanks, and more. It provides immediate notification of threatening high water levels.

The VertiMAC Sump Advisor is a float operated pump switch system, typically used in sump pump applications or situations where a regular pump switch cannot operate due to limited space. A Sump Advisor sensor is attached to the top of the VertiMAC pump switch, eliminating the need to mount a separate alarm float switch. The sensor integrates high level alarm and pump run switches that are connected to the Sump Advisor alarm panel. The alarm panel has a 9-volt battery backup (customer supplied) and auxiliary dry contacts for high level alarm and pump run status that can be connected to a building automation system (BAS) or auto dialers. Available in 120VAC or 240VAC, bare lead (no plug) or piggyback plug, 13 Amp models.

PHCC Pro Series Connect Wi-Fi Module is designed for easy installation, linking the pump systems to a home Wi-Fi, security system, or home automation system. Notifications can be sent by email or a text message to a smartphone, tablet, or computer.

PS-Wi-Fi module connects wireless to PHCC servers that watch over the sump pump system automatically. The servers constantly collect and analyze incoming data from the sump pump or battery backup, checking for potential issues. When an issue is detected, PS-Wi-Fi automatically sends alarm text messages.

The DFC2 and VFC2 alarms (LED, Beep) and remote notification terminals activate when: AC power is out; pump ran for 10 minutes continuously; and the 9-volt alarm backup battery is low. A flashing green light indicates the controller is active. The latest model has a plug on the bottom to allow the water sensor float (sold separately) to be plugged in to provide an instant audible, LED, and remote notification based on water level.
