DX Grinder Pump Specification (DOC)


The DX502 grinder pump station consists of two model DX explosionproof grinder pumps in 500-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 DX502 can accommodate flows of 6000 gallons per day. Stations are available in heights of 129 inches and 160 inches.
