ABSTRACT:
A mud pump assembly has a housing having a motor-mounting face directly connected to a standard hydraulic drive motor. The pump housing supports and partially encloses a bearing assembly which supports the pump impeller shaft. A face-type impeller shaft seal is located between the bearing assembly and the impeller. The motor case completes enclosure of the impeller shaft bearing assembly. A motor case drain line is coupled to the mud pump housing for continuous pressure lubrication of the bearing assembly. In one embodiment, case drain fluid is returned from the mud pump housing to the hydraulic fluid reservoir for the hydraulic motor.
