E/One WH101 Grinder Pump

E/One WH101 Grinder Pump

The W-Series is E/One’s most versatile sewage grinder pump station — a range of basins, covers, discharges, inlets and panels are available. The E/One WH101 Grinder Pump can pump wastewater from the home to the central sewer and/or treatment system through small-diameter pipes.

Featuring the new E/One Extreme grinder pump, the WH101 offers a new level of reliability and ruggedness.


The Grinder Pump station consists of a pump inside an open wet well tank. The  pump, motor controls and level-sensing are integrated into a compact unit, easily removable for service.

Solids are ground into fine particles that pass easily through the pump, check valve and small-diameter pipe lines — even objects that are not normally found in sewage, such as plastic, rubber, fiber, wood, etc. The 1-1/4″ discharge connection can be adapted to any piping materials that meet local code requirements.

The tank is made of tough corrosion-resistant HDPE. The optimum tank capacity of 100 gallons is based upon computer studies of water usage patterns. A single E/One WH101 Grinder Pump can accommodate the sewage flow from two single family homes or up to 700 gallons per day.

The internal check valve assembly, located in the pump, is custom designed for non-clog, trouble-free operation.

The E/One WH101 Grinder Pump is automatically activated. It runs infrequently for very short periods. The annual energy consumption is typically that of a 40-watt light bulb.

Units are designed to accommodate a wide range of depths; tank height can be adjusted in the field.
