D-Series | DH152 & DR152 Grinder Pump Station
The E/One model DH152/DR152 duplex grinder pump station is an ideal choice for multiple single-family homes and light commercial applications. Grinder pumps send wastewater from the home to the central sewer and/or treatment system through small-diameter pipes.
Featuring the E/One Extreme grinder pump, the DH152/DR152 offers a high level of reliability and ruggedness.
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. The grinder pumps, motor controls and level-sensing are integrated into compact units, easily removable for service.
- 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.
Solids are ground into fine particles that pass easily through the pumps, check valves 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 connections can be adapted to any piping materials that meet local code requirements.
The tank is made from tough, corrosion-resistant polyethylene and offers 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.
Units are available for indoor and outdoor installations. Outdoor units accommodate a wide range of depths. E/One requires the installation of its stainless steel UNI-LATERAL to prevent backflow from the sewer system from entering the grinder pump station.
About the E/One Grinder Pump
The grinder pump is automatically activated and runs for very short periods. Electrical consumption of the grinder pump is low and will vary with actual water consumption.
E/One grinder pumps do not require preventive maintenance and boast an average of eight to 10 years between service calls. If service is required, the one-piece core eliminates the need for in-field troubleshooting and servicing — the pump core can be quickly pulled out and replaced, meaning minimal maintenance costs and inconvenience for the property.
Motors: 1 HP, 1725 rpm, high torque, capacitor start, thermally protected, 240 or 120 volt, 60 hertz, 1 phase
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.

A dedicated 30A breaker is required, with #10 wire, for 240V single phase. You need to bring L1, L2, N and Gnd to the E/One panel.
If only 208V power is available, a buck boost transformer is required to boost 208V to 240V. The E/One pump requires a minimum of 216V to start and run reliably.
