Grinder pumps are typically used for heavy duty shredding with a grinding ring at the input point, and have an open impeller, centrifugal design preventing blockages of the pump or pipework. A 304SS grade steel for the shaft, motor shell and fasteners ensure a long service life.

With silent operation and quick, easy installation, the Davey Grinder range is a low maintenance product to help pump soft organic solids, sanitary products, thin rubber and even some textiles by shredding them into a slurry, easily pumped from there.
