The wastewater packaged lift station with submersible SEG grinder pump from Grundfos is designed for collecting and transferring wastewater from buildings, pressurized municipal sewage systems and industrial applications. The lift station can also be used with SL1/SLV submersible wastewater pumps to transfer untreated sewage.

While new to North America, the lift station package has been used in Europe for about 10 years.

“We’ve had several generations that we’ve gone through with this product where we have continuously improved it,” says Thomas Morrison, Grundfos water utility sales and business development director for North America. “What we really focused on delivering with this product is not the low-cost end of the market but improving the overall cost of ownership. The way to do that is making a high-quality product that is very reliable, minimizes downtime, and when you do have downtime, make the product very easy to service and get back into operation.”

The 2 to 5.5 hp grinder pumps devour diapers, nylon stockings, feminine hygiene products, plastic bags, dish towels, protective gloves, dish cloths, rubber bands and other debris.

One pump delivers up to 160 gpm; capacity doubles with duplex systems.

Pump features include cable connection to the motor via a cable plug filled with a two-component compound for a hermetically sealed cable entry. Other features include a cartridge shaft seal and SmartTrim impeller adjustment for optimum performance.

“Another unique design feature is the pump volute and motor housing is held together by a stainless steel clamp that you can remove without the use of any tools,” Morrison says. “That allows you to quickly and easily inspect the impeller, volute and cartridge seal in the field.”

Made of corrosion-free materials, the ready-to-install lift station package includes a polyethylene tank, stainless steel piping, valves and controllers. The modular packages are available with 32-, 40- or 48-inch sump diameters and four standard depths for simplex or duplex pump installation. Tank heights range from 60 to 118 inches. The sump diameter is approximately 8 inches larger than the well diameter to prevent push-up, eliminating the need for a concrete base plate. System modeling is also available. Accessories include sleeves for ducts, ventilation package, level control and monitoring.

“One of the key benefits here is an operator gets the complete system from one vendor,” Morrison says. “It’s not something that has been pieced together by two, three, four, five different manufacturers and put together by a distributor. This is a complete engineered system from one manufacturer and one vendor.” 800/921-7867; http://us.grundfos.com.
