Features
The DH071 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.
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. The optimum tank capacity of 70 gallons is based on computer studies of water usage patterns. A single DH071 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 can accommodate flows of 700 gallons per day.
The grinder pump is automatically activated and, because it runs infrequently and for very short periods, its annual electric energy consumption is typically that of a 40-watt light bulb.
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.
Operational Information
Motor
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.
Discharge*
15 gpm at 0 psig
11 gpm at 40 psig
7.8 gpm at 80 psig
Overload Capacity
Maximum pressure that the pump can generate is limited by motor characteristics to a value well below the rating of the piping and appurtenances. Automatic reset feature does not require manual operation following overload.
US and foreign patents issued and pending.
*Discharge data includes loss through check valve, which is minimal.
