Abstract
The impeller axial lock limits axial movement of an impeller disposed on a shaft. The impeller is spaced axially from a shaft sleeve disposed about the shaft. The impeller axial lock includes a ring member disposed about the shaft between the impeller and shaft sleeve. The ring member has a body defining a first engagement tab engaging the impeller, a second engagement tab engaging the shaft, and a third engagement tab engaging the shaft sleeve. The shaft sleeve secures the ring member to the shaft via the third engagement tab such that the ring member limits axial movement of the impeller on the shaft during rotation of the impeller. The second engagement tab engages a groove in the shaft, and the third engagement tab engages a groove in the shaft sleeve.
