E/One's WH101F/WR101F 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 WH101F is the “hardwired,” or “wired,” model where a cable connects the motor controls to the level controls through watertight penetrations.
- The WR101F 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. The WH101F/WR101F is a watertight, sealed station that is capable of sustaining a 15-foot flood above the top of the station. This type of flood condition will not affect the continued operation of the pump; the homeowner should rely on uninterrupted service.
The internal check valve assembly, located in the grinder pump, is custom designed for non-clog, trouble-free operation. 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.
