E/One DH502 Grinder Pumps

E/One DH502 Grinder Pumps

The E/One model DH502 duplex grinder pump station is an ideal choice for multiple single-family homes. The pumps send wastewater from the home to the central sewer and/or treatment system through small-diameter pipes.

Featuring the new E/One Extreme grinder pump, the DH502 offers a new level of reliability and ruggedness.

It consists of two pumps and tank. The grinder pumps, 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 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 FRP. The optimum tank capacity of 500 gallons is based on computer studies of water usage patterns. A single DH502 can be used for nine average, single-family homes, and up to 24 homes where codes allow and with consent of the factory. The DH502 can accommodate flows of 6000 gallons per day.

The grinder pumps are automatically activated and, because they run 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.
