E/One DH152 grinder pump station

The E/One model DH152/DR152 duplex (2 pumps) grinder pump station is an ideal choice for multiple single-family homes and light commercial applications. Grinder pumps collect wastewater from the building and send it to the central sewer and/or treatment system through small-diameter pipes.

This model was previously known as the Model GP 214 or Model GP 2014.

The DH152/DR152 grinder pump station consists of two pumps and 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 DH152 is the “hardwired,” or “wired,” model where a cable connects the motor controls to the level controls through watertight penetrations.
  • The DR152 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 from tough, corrosion-resistant polyethylene and provides 150 gallons of capacity. A single DH152/DR152 is ideal for light commercial applications. It is ideal for up to four, average single-family homes and can be used for up to 12 homes where codes allow and with consent of the factory. The DH152/DR152 can accommodate flows of 3000 gallons per day.

Stations are available for indoor and outdoor installations. Outdoor stations accommodate depths from 93 inches to 160 inches (refer to 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 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.
