PRODUCT DESCRIPTION
Submersible grinder pumps are recommended for use in basins or lift stations and are suitable for pumping
residential sewage, effluent, wastewater, and other non-explosive, non-abrasive, and non-corrosive liquids.
These pumps utilize a cutting mechanism, located on the suction side of the pump, that cuts solids into a
slurry. A semi-vortex, non-clog impeller then passes this slurry directly through the volute and into the dis-
charge line.
Little Giant automatic grinder pumps are equipped with a float switch that allows the pumps to operate
automatically by cycling them on and off. The float switch is attached to the pump at a pre-determined
tether length of 6 inches. Check the tether length on the pump to ensure it has not changed during ship-
ping. Some pumps, however, come with an unassembled mechanical vertical switch.
This product is covered by a Limited Warranty for a period of 36 months from the date of original purchase
by the consumer. For complete warranty information, refer to www.LittleGiant.com; or call Customer Sup-
