Abstract
An open face cooling system for a motorized, impeller-type, submersible pump operated in a host fluid ladened with solids, comprising an inlet in the pump housing close to the impeller and away from the axis of the pump into which fluid is forced by pump pressure, the inlet arranged so the impeller vanes sweep its face with a shearing motion that reduces the size of any solids present there until they are small enough to enter the inlet with the fluid flow, the materials ladened fluid flowing hence through a coolant conduit, out of a tangentially configured nozzle into a rotational flow around the inside of an open face toroidal section, and hence inward through an adjoined, inward extending distribution section configured co-axially around and above the motor, to be discharged upon the motor.
