Features
The DH502 grinder pump station consists of two pumps and a tank with a dry accessway. The grinder pumps use integrated level-sensing pressure switches instead of floats — the "core"-style pump is compact and easily removed for service if needed.
The tank is made from tough, corrosion-resistant FRP and provides 500 gallons of capacity. A single DH502 can be used for nine average, single-family homes, and up to 24 homes where codes allow and with consent of the factory. The DH502 can accommodate flows of 6000 gallons per day.
Stations are available for outdoor installations and can accommodate depths from 102 inches to 160 inches (see drawings above).
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.
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.
