Features
E/One's WH101/WR101 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 is the “hardwired,” or “wired,” model where a cable connects the motor controls to the level controls through watertight penetrations.
- The WR101 is the “radio frequency identification” (RFID), or “wireless,” model that uses wireless technology to communicate between the level controls and the motor controls.
The tank is made of tough, corrosion-resistant HDPE and offers 100 gallons of capacity. A single WH101/WR101 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.
Inlet Connections: 4" inlet grommet standard for DWV pipe. Other inlet configurations available from factory.
Discharge Connections: Pump discharge terminates in 1-1/4" NPT female thread. Can easily be adapted to 1-1/4" PVC pipe or any other material required by local codes.
