ABSTRACT:
The impeller mounting apparatus includes one or more pins extending through the hub into the shaft with the pins being retained in the holes by means of a resilient metallic band of continuous construction which is forced onto the hub into grooves or recesses which prevent the dislodgement of the band and the inadvertent loosening of the impeller on the shaft.
