Powered by a 1/35 horsepower open, fan-cooled motor, the 1.5-MDI-SC Series from Little Giant is constructed of durable materials to handle moderately corrosive chemicals. Its glass-filled polypropylene magnetic housing, volute, and impeller are excellent for chemical resistance. The 1.5-MDI-SC is also equipped with ceramic shaft and thrust washers that are 99.5% pure alumina for excellent wear resistance and trouble-free service.
