A high pressure water pump system, including a motor (20), an intermediate flange (30) and an axial drive water pump (60) wherein the intermediate flange unites the motor and the high pressure water pump. A wobble disk assembly (62) is attached to an end of the drive shaft of the motor and located in a second recess (36) of the intermediate flange. The intermediate flange (30) is shaped to receive the wobble disk assembly (62). Thrust bearings, consisting of thrust washers (41) and cylindrical or spherical rollers (42), are located in a first recess (34) of the intermediate flange (30) and act on a part of the wobble disk assembly. A bushing (43) made of sintered ferrous material or of plastic material is press-fitted between the first recess (34) and the back part (63) of the wobble disk assembly (62). A plug (45) is applied to the end of the drive shaft (22).
