A pump, for coolant or other working fluids, is provided which can require less mounting area than prior art pumps by removing the need for pump volutes. The pump includes a series of diffuser channels formed between stator vanes on the pump housing and an outwardly inclined lip about the periphery of the impeller. The diffuser channels and the inclined lip serve to direct pressurized working fluid to exit the outlet of the pump in an axial direction, generally parallel to impeller shaft. The relatively long centre passage through the pump housing, through which the working fluid is supplied from the inlet to the impeller, reduces turbulence in the working fluid before it reaches the impeller, reducing the chances of cavitation occurring at the impeller.
