ABSTRACT:
A floating, self-centering impeller for a turbine pump assembly has a plurality of "D-shaped" recesses arranged in one or more circumferential rows on its end surfaces to induce pressurized film between its end surfaces and adjacent thrust surfaces of side plates to prevent galling or seizing of the pump as the impeller is rotated. A corresponding array of such "D-shaped" recesses may be provided on the opposing surfaces of the side plates.
