摘要

An electric coolant or water pump with a housing including and a housing sleeve adapted to receive a bearing assembly. An integral shaft bearing assembly is mounted inside the housing sleeve. The integral shaft bearing assembly includes a shaft, an outer bearing ring, and at least one bearing located between the shaft and the outer bearing ring. An impeller is connected to the shaft and located in the pump chamber. An electric motor is mounted to the housing, with the electric motor including a stator connected to an outside of the housing sleeve and a rotor mounted to the shaft on an opposite end from the impeller. The rotor is located opposite from and rotatable relative to the stator.
