Stanley Hydraulics Submersible Pump - SM50100

Stanley Hydraulics Submersible Pump - SM50100

The SM50 Water Pump is a submersible, centrifugal type pump that requires no priming. The motor is contaminant-tolerant gear motor uniquely designed for continuous highspeed operation. The motor drives the impeller directly, so there are no spindle bearings that require periodic lubrication or replacement. The cast stainless steel, semi-closed impeller resists corrosion. A series of seals on the drive shaft effectively keep hydraulic fluid and pumped water where they belong while allowing the pump to be run dry without sudden seal failure.
