Features
The WX grinder pump. The grinder pump, 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 standards 3600, 3610, and 3615).
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 pump is available with several different discharge hose lengths to accommodate a range of tank 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 — a building 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 property.

Electrical Information
For a standard 240V single-phase installation, a dedicated 30A breaker is required, with #10 wire, to the E/One panel. You need to bring L1, L2, N and Gnd.
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.
