About Liberty Sump Pumps

Most Liberty sump pump models can be categorized into sump pumps with cast iron and aluminum housing. Aluminum models offer a better heat dissipation than cast iron and come with a plastic base, which, if removed, allows suction down to 1/8". Select cast iron pump series feature a Liberty’s unique “Powder Coated Tough” one-piece housing, which resists corrosion better then similar models from competitors and has a longer estimated life span.
Standard cord options for 115V pumps are 10ft and 25ft, with 35ft and 50ft power cord models also available.

Manual sump pump models are operated in manual mode only by plugging the power cord into the electrical outlet, or in automatic mode by using a compatible external control.
Automatic models feature a wide-angle style float or a vertical magnetic float which regulates the On-Off operation of the pump.
