Grinds and moves effluent from a larger sewer main into a smaller, pressurized line uphill or a long distance. Required in some new Sedona subdivisions with pressurized sewer mains. An environmental grinder pump has a large capacity overflow tank.
A small submersible centrifugal pump with an impeller designed with grinder elements installed that both serves as a pump, and grinds solids in the pumped liquid into small pieces that can pass through the pump impellers, and downstream piping.
A grinder pump is a waste management device. Waste from water-using household appliances (toilets, bathtubs, washing machines, etc.) flows through the homeâ€™s pipes into the grinder pumpâ€™s holding tank. Once the waste inside the tank reaches a certain level, the pump will turn on, grind the waste into a fine slurry, and pump it to the central sewer system.
