WX Grinder Pump Specification (DOC)


The WX grinder pump. The grinder pump, motor controls and level-sensing are integrated into a compact unit, easily removable for service.

The pump is rated for explosionproof under Factory Mutual standards (approval standard 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.
