Features
E/One's WH101 grinder pump station consists of a pump inside an open wetwell tank. The grinder pump, motor controls and level-sensing are integrated into a compact unit, easily removable for service.
- The WH101 model has a cable that connects the motor controls to the level controls through watertight penetrations.
The tank is made of tough, corrosion-resistant HDPE and offers 100 gallons of capacity. A single WH101 can accommodate the sewage flow from two single family homes or up to 700 gallons per day.
Units are available to accommodate a wide range of depths. E/One requires the installation of its stainless steel UNI-LATERAL to prevent backflow from the sewer system from entering the grinder pump station.
