ABSTRACT:
A high-speed pitot pump has a system for self-cooling the lubricant for the bearings supporting the rotatable casing of the pump. The lubricant is contained in a reservoir which is continuously cooled during operation of the pump. The pump has a rotatable casing cantilevered on a shaft in the pump housing. The lubricant cooling system includes blower means which rotate with the casing to draw cool air into the housing and force it through a discharge opening which directs the flow of cool air toward a heat exchanger, preferably a series of cooling fins projecting from an exterior wall of the reservoir.
