Claims

[Scope of Claim for Utility Model Registration] (1) Consists of a motor section and a pump section that are liquid-tightly partitioned via a partition wall, and a drive magnet is connected to the motor shaft of the motor section via a drive rotating body concentrically with the motor shaft. In a magnet-driven pump, in which the driven magnet is supported along a cylindrical surface and the driven magnet is supported along a cylindrical surface concentric with the pump shaft through a driven rotating body of the pump shaft of the pump section, the driving magnet and the driven magnet are each circularly supported. A magnet-driven pump characterized in that the pumps are arranged at appropriate intervals in the circumferential direction. (2) The magnet-driven pump according to claim 1, wherein the drive rotor is omitted except for a portion that supports the drive magnet. (3) Claim 1 or 2, wherein the driven rotor is removed except for a portion that supports the driven magnet, and the deleted portion is formed into a long groove with a truncated circular cross section along the axis of the driven rotor. Magnetically driven pump as described.
