PROBLEM TO BE SOLVED: To achieve high efficiency, miniaturization, and long life. SOLUTION: A cylindrical body 4 having the circular section is rotatably and watertightly supported on both ends of a housing main body 8. A cage- shaped coil is formed on a cylindrical body 14 mounted on the cylindrical body 4, and a stator is provided inside the housing main body 8 by a coil 20 and a laminated iron 16. Guide vanes 24 are attached to an extending part 4B of the cylindrical body 4, and openings 4C are formed. Electric power is supplied to an electric motor composed of the cage-shaped coil and the stator, the guide vanes 24 are rotated when the cylindrical body 4 is rotated, water in a spiral chamber forming housing 28 is allowed to flow into a spiral chamber 28B by centrifugal force, pressurized and discharged from a discharging port 30A. Simultaneously, water is sucked from a suction pipe 32, and pumping is performed. |
