A fluid pump includes an inlet plate and an electric motor. The electric motor has a shaft that rotates about an axis. A pumping arrangement is rotationally coupled to the shaft. The pumping arrangement includes an rotating element. The fluid pump further includes a thrust bearing driver including a disc-like plate having first and second faces, and two posts extending perpendicularly from the first face. The shaft has a terminal end including a pair of slots that cooperate with the posts of the thrust bearing driver. The inner gear rotor has an inner surface including a pair of slots that cooperate with the posts of the thrust bearing driver. The posts of the thrust bearing driver are received in the slots of both the shaft and the rotating element, and the thrust bearing driver is sandwiched between the shaft, the inlet plate, and the rotating element.
