Features
E/One's WH472 grinder pump station consists of two Extreme series grinder pumps inside an open wetwell tank. The grinder pumps, motor controls and level-sensing are integrated into compact units, easily removable for service.
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 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.
