D-Series | DH272 & DR272 Grinder Pump Station
The E/One model DH272/DR272 duplex 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 2015.
Drawings & Installation Instructions
The DH272/DR272 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 DH272 is the “hardwired,” or “wired,” model where a cable connects the motor controls to the level controls through watertight penetrations.
- The DR272 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 FRP and offers 275 gallons of capacity. A single DH272/DR272 can be used for six average, single-family homes, and up to 20 homes where codes allow and with consent of the factory. The DH272/DR272 can accommodate flows of 5000 gallons per day.
Stations are available for indoor and outdoor installations. Outdoor stations accommodate depths from 97 inches to 160 inches.
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.
