ABSTRACT:
An integrated motor-driven pump includes an electromagnet disposed in the pump casing opposite a magnet mounted to an impeller of the pump. The impeller is rotatably supported within the casing, and is rotated by inducing a repulsion force in the magnet. In addition, a bearing rotatably supporting the impeller is provided in a portion of the casing formed with a flow passageway which leads working fluid handled by the pump flow to both sides of the bearing so that the bearing can be lubricated and cooled by the working fluid.
