ABSTRACT:
A hub mounting assembly for mounting a plurality of impellers onto a shaft has a first hub ring and a second hub ring. A first key piece is adapted to engage with the shaft and engage with at least one of the hub rings, and a first lock pin is adapted to engage with the shaft and engage with at least one of the hub rings. In the installed state, the first hub ring is adapted to be fastened to the second hub ring, to trap the key piece and lock pin in a position so that the hub rings together form a hub that is locked against rotation and axial movement with respect to the shaft.
