ABSTRACT:
In the first embodiment of the present invention, the armature of the motor is rotatably fitted through the bearings provided at both ends of its rotary shaft. A rotor is rotatably mounted through a fixed shaft arranged differently from the rotary shaft to form a pump means. The rotary shaft and the rotor are connected by a connector means in such a manner that the radial displacement of both axes of the rotary shaft and the rotor can be absorbed by the connector.
In the second embodiment of the present invention, a pump housing of a pump means is adapted partly to serve as a part of the casing of the electrically powered pump. An inlet of the pumped liquid is formed in the pump housing and a union is integrally formed with the casing.
In the third embodiment of the present invention, the armature of the motor is rotatably fitted through the bearings provided at both ends of its rotary shaft. At least two stages of impellers are rotatably mounted to the fixed shaft arranged in axially alignment with the rotary shaft to form a pump means. The rotary shaft and the impellers are connected by a connector means in such a manner that the relative motion in a circumferential direction of the rotary shaft and the impellers is restricted.
