摘要：A coolant pump for use with an internal combustion engine having a crankshaftand a camshaft driven by the crankshaft includes a pump housing fixedly mountable tothe engine. The pump housing includes an inlet opening to receive coolant and an outlet

opening to discharge coolant. An impeller shaft is operatively coupled to the camshaft soas to be rotatably driven thereby. A pump impeller is operatively mounted to theimpeller shaft within the pump housing, the pump impeller rotatable to draw the coolantinto the pump housing through the inlet opening and discharge the coolant at a higherpressure through the outlet opening. The pump impeller includes first and secondshrouds separated by a plurality of vanes. The first and second shrouds and plurality ofvanes are configured and positioned such that a resultant thrust load acting on the pumpimpeller and hence the impeller shaft is approximately zero.
