PROBLEM TO BE SOLVED: To provide a magnetic pump having compact construction. SOLUTION: A partition wall 13 is provided on the inner periphery of a cylindrical motor housing 11. At both ends of the motor housing 11, a casing body 14 is mounted to form two pump chambers 23 in the motor housing 11. A rotating shaft 20 is provided on the partition wall 13 and a rotor 17 is mounted on the rotating shaft 20. The rotor 17 has a magnet 15 and an impeller 16. A liquid inlet 14a and a liquid outlet 14b are formed in the center of the casing body 14 and in part of the outer periphery thereof, respectively. A coil 12 is mounted on the motor housing 11 so that the excitation of the coil 12 rotates the rotor 17 with magnet joint. With the motor housing 11, the rotor 17 and the casing body 14, pump parts 10a, 10b are formed at both ends of the motor housing 11. A motor part 10c is formed with the coil 12 and the magnet 15. The two pump parts 10a, 10b contribute to compact construction. COPYRIGHT: (C)2007,JPO&INPIT
