The 3-MD-SC Series is engineered for semi-corrosive chemicals and solutions featuring rotatable pump heads for easy maintenance. This pump is equipped with a thermally protected 1/12 hp open fan-cooled motor with ball bearings, a 6′ power cord, and a 3-prong molded plug.
The Little Giant 3-MD-SC Chemical Pump is designed to handle semi-corrosive chemicals and features leakproof, seal-less magnetic drives, and is designed for in-line, non-submersible use. Volute, magnet housing, and impeller are made of glass-filled polypropylene for excellent chemical resistance. Ceramic shaft and thrust washers are 99.5 percent pure alumina for excellent wear resistance and trouble-free service. The washers do not revolve to prevent wear on the shaft.
