Liberty Pumps 457 is a submersible sump pump with a deep-finned, powder-coated aluminum motor housing that provides 225% more cooling capacity than cast iron housings, Comes with a 1/2 horsepower and can discharge up to 1-1/2 inches and can handle solids up to 3/8 of an inch, making it ideal for use in a variety of applications, including draining flooded basements, crawl spaces, and other areas where water accumulation is a problem.

The pump's vortex-style impeller allows it to pass solids without clogging, and its polypropylene and powder-coated aluminum construction make it corrosion-resistant and durable. The stainless steel rotor shaft, non-corrosive stainless steel fasteners, and oil-filled, hermetically sealed motor with thermal overload protection ensure long-lasting performance.
