PURPOSE:To reduce the number of necessary parts for simplifying the assemblying and disassembling of a magneto-pump, by arranging two pumps each having a driven magnet therein, at the inner and outer peripheries of a drive magnet, respectively. CONSTITUTION:A funnel shape magnet holder 2 having one end supported to one end of the shaft 1B of a motor 1, supports at the other end a cylindrical drive magnet 3. A first pump 4 and second pump 5 carry out pumping operation when the drive magnet 3 is rotated by the operation of the motor 1, since first and second magnets 42, 52 are driven to rotate. Accordingly, the number of necessary drive magnets may be reduced to only one so that the number of necessary parts may be reduced, thereby the assemblying and disassemblying of the pump are simplified. |
