Little Giant and Liberty Pumps grinder pumps are used in wastewater applications to grind the sewage waste into a fine slurry, preventing blockage of the pumps and drainage system. Available models include 1HP residential and larger (up to 2HP) commercial grinder pumps.
About Grinder PumpsA grinder pump is designed to solve the problem of sewage blockage caused by diapers, gloves, food and other articles which clog a typical sewage pump system, resulting in downtime and added maintenance costs. A grinder pump incorporates a sharp, motor-driven blade which grinds the incoming waste into a slurry and allows it to be discharged without obstructing the drainage piping or the pump impeller.
While mostly used in commercial settings, like restaurants, shopping malls and other high-traffic institutions, smaller size sewer grinder pumps can also be used in residential settings.
Automatic sewer grinder pump models incorporate a wide angle float switch which turns the pump on or off at designated water levels. Wide angle float is secured by a clamp to the pumps’ body and allows to adjust the length of the unsecured portion of the float to regulate the on/off levels.
Manual grinder pumps can be used for manual dewatering of sewage basins or collecting tanks. Select control options allow to wire one or more manual pumps and run them in automatic mode.
