W-Series | WH472 & WR472 Grinder Pump Station

The WH472/WR472 is one of E/One’s largest-capacity grinder pump stations. This duplex (2 pumps) station offers a capacity of 476 gallons and can handle flows of up to 3500 GPD.

Features

E/One’s WH472/WR472 grinder pump station consists of an Extreme series grinder 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 internal check valve assembly, located in the grinder pump, is custom designed for non-clog, trouble-free operation.

  • The WH472 is the “hardwired,” or “wired,” model where a cable connects the motor controls to the level controls through watertight penetrations.
  • The WR472 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 polyethylene. Designed specifically for low pressure sewer applications, the optimum tank capacity of 476 gallons provides ample storage. A single WH472/WR472 can accommodate flows of up to 3500 gallons per day.

Stations are available in several heights to accommodate various burial depth requirements. See drawings (above) for more information. 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 PVC 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
