Features

The DX272 grinder pump station consists of two model DX explosionproof grinder pumps in a 275-gallon tank. The grinder pumps, motor controls and level-sensing are integrated into a compact unit, easily removable for service. The pumps are rated for explosionproof under Factory Mutual standards (approval standard 3611).

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 DX272 can accommodate flows of 5000 gallons per day. Stations are available in heights of 129 inches and 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.

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.

Electrical Information

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.
