Features
E/One's WH101F 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.
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 WH101F 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.
The 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.
Operational Information
Motor
1 HP, 1725 rpm, high torque, capacitor start, thermally protected, 240 or 120 volt, 60 hertz, 1 phase
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.
Discharge*
15 gpm at 0 psig
11 gpm at 40 psig
7.8 gpm at 80 psig
Overload Capacity
Maximum pressure that the pump can generate is limited by motor characteristics to a value well below the rating of the piping and appurtenances. Automatic reset feature does not require manual operation following overload.
US and foreign patents issued and pending.
*Discharge data includes loss through check valve, which is minimal.
