Engine Cooling Pump - Pulley Driven

Model 401M Rubber Impeller Pump

Bronze Construction with Pedestal Mount

This pump with 5/8" diameter shaft projection is suitable for either direct drive with flexible coupling or pulley drive. Direction of shaft rotation determines inlet and outlet ports (see line drawing). Pump will operate satisfactorily when mounted in any position, but do not run dry. Note: Rubber impeller pumps generate high rubbing friction unless lubricated by pumped liquid. Lack of liquid will cause impeller to burn up.

While intended for engine coolant, liquids compatible with Neoprene that can be pumped include fresh and saltwater solutions and mild chemicals. Do not pump severe solvents or acids, and whenever possible, flush pump with fresh water after usage. Buna-N rubber seal between body and cover eliminates gasket problems. Suction lift of 15 feet is possible when impeller is wet. Suction lines must be airtight in order for pump to self prime. A foot valve at beginning of suction line is recommended.

Rugged construction with extra-capacity ball bearings ensure a prolonged service life.
