ABSTRACT:
An impeller and shaft assembly includes an outwardly tapered socket 38 in the rear face of the impeller 12 and into which a frusto-conically shaped extremity 20 seats, the extremity circumferential wall having a plurality of axially extending grooves 42 alternating with intervening lands 44, the socket and extremity being dimensioned and configured so that in the finally seated relation of the parts the land plastically deforms the socket material which has a lower compressive yield strength than the extremity.
