Wet-Pit Type Submersible Grinder Pumps

All of our grinder pumps are wet-pit design. Sewage enters the wetwell and the pump
then pumps into the forcemain. Grinder pumps can be of two styles, centrifugal and
positive displacement.

Grinder pumps are typically used in developments or single family homes for pressure
sewer applications. A grinder pump is an efficient method to provide sewers to difficult
rocky, hilly or high water table areas. A grinder pump may be the only option.

Grinder pumps are usually a cost-effective solution for small subdivisions or commercial
applications. Usually it has a lower installed cost than a non-clog pump, but the
maintenance of the grinder shredding ring increases the cost for the end user.

Applications include:
Rocky grades, lake communities and single-family homes typically no more than 50
homes in a duplex grinder pump station, if pumping to a lagoon or a 4" forcemain
then use non-clog pumps.
