Abstract
A vehicle water pump includes a unit handled assembly comprising a bearing housing, pump housing, and annular wear face sealing element, all made of suitable steels and alignable relative to one another at a common, accessible juncture of three circular edges. The components can thus all be welded together to give an easily handled unit, and the metal wear face has a much improved alignment, life and running temperature, as compared to a conventional ceramic wear face.
