ABSTRACT:
An electric motor includes a pump leg on the driving side thereof, and a bracket, a flange, discharge joints, extension tubes and a volute chamber cover are integrated into the pump leg 6. The extension tubes are arranged opposite to each other at the positions spaced away from each other by an angle of about 180 degrees in the circumferential direction. A volute chamber of a first pump and a volute chamber of a second pump are formed integral with a distance suction casing fixedly secured to the lower surface of the pump leg while a suction port for the first pump is located opposite to a suction port of the second pump. In addition, a volute chamber cover is fixedly secured to the lower surface of the distance suction casing. The volute chamber is communicated directly with the extension tube, while the volute chamber is communicated with the extension tube via an intermediate discharge port which is formed integral with the distance suction casing while extending in the axial direction in the region located sideward of the volute chamber.
