About the DH071/DR071 Grinder Pump Station

Jim Welsh, E/One Field Service, describes the DH071/DR071 grinder pump station:

Features

The DH071/DR071 grinder pump station consists of a pump and tank. The grinder pump, motor controls and level-sensing are integrated into a compact unit, easily removable for service.

  • The DH071 is the “hardwired,” or “wired,” model where a cable connects the motor controls to the level controls through watertight penetrations.
  • The DR071 is the “radio frequency identification” (RFID), or “wireless,” model that uses wireless technology to communicate between the level controls and the motor controls.

Solids are ground into fine particles that pass easily through the pump, check valve and small-diameter pipe lines — even objects that should not be 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 from tough, corrosion-resistant HDPE and offers 70 gallons of capacity. A single DH071/DR071 is ideal for one, average single-family home and can be used for up to two homes where codes allow and with consent of the factory. The DH071/DR071 can accommodate flows of 700 gallons per day.

Units are available for indoor and outdoor installations. Outdoor units accommodate a wide range of depths, suitable for both warm and cold climates. 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. E/One requires the installation of its stainless steel UNI-LATERAL to prevent backflow from the sewer system from entering the grinder pump station.
