Abstract: Disclosed embodiments include a pump assembly comprising a pump including a rotating drive shaft having a tapered end portion, a first alignment structure on the drive shaft, and a hub adapter including a first mounting portion comprising a tapered opening and a second mounting portion extending from the first mounting portion and configured to receive a drive member. The tapered opening is configured to be inserted onto and engaged with the tapered end portion of the drive shaft. A second alignment structure is located on the hub adapter, and the first alignment structure and the second alignment structure cooperate to enable a predetermined registration of the hub adapter on the drive shaft. A fastener structure secures the hub adapter to the drive shaft.
