D-Series | DH071 & DR071 Grinder Pump Station
The E/One model DH071/DR071 simplex grinder pump station is an ideal choice for single-family homes. Grinder pumps pump wastewater from the home to the central sewer and/or treatment system through small-diameter pipes.
Featuring the E/One Extreme grinder pump, the DH071/DR071 offers a high level of reliability and ruggedness.
This model was previously known as the Model GP 210 or Model GP 2010.
Drawings & Installation Instructions
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.
The grinder pump is automatically activated and runs for very short periods. Electrical consumption of the grinder pump is low -- a household that uses 250 gallons of water per day should use less than 10 kwhr per month to run the pump. (Actual water and power usage will vary.)
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 unique, 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 homeowner.
Units are available for indoor and outdoor installations. Outdoor units accommodate a wide range of depths.
Motor: 1 HP, 1725 rpm, high torque, capacitor start, thermally protected, 240 or 120 volt, 60 hertz, 1 phase
