E/One Sewer Systems is the market leader in pressure sewer systems. E/One developed the grinder pump for residential, commercial, industrial and municipal use more than 45 years ago and serves more than 1 million end users daily.


E/One offers a 3/4 hp semi-positive displacement (SPD) type grinder pump for residential wastewater use. The pump is appropriate for low-pressure applications that have a maximum head of 28 meters.

The progressing cavity pump itself is based on the Moineau principle. A rotor turns within a stator, creating a sequence of sealed chambers. The precision-cast and polished stainless-steel rotor move wastewater through these chambers at a nearly constant flow, over a wide range of conditions – from negative to abnormally high heads. Turning at just 1450 rpm, the 0.56-kilowatt motor can pump fluid through more than 1.5 km of small- diameter piping or elevation changes of up to 28 meters.
