Abstract (en)
A full-circumferential-flow double-suction pump having impellers on respective opposite ends of the shaft of a motor, with an annular space or flow passage defined around the motor. The vertical double-suction pump has an outer cylinder and a motor housed in the outer cylinder. The motor has a stator and a rotor rotatably disposed in the stator. The outer cylinder defines a flow passage defined around the stator. A main shaft which supports the rotor extends substantially vertically. The pump also includes a pair of upper and lower impellers mounted respectively on upper and lower ends of the main shaft in communication with the flow passage. <IMAGE>
