Claims

[Claims for Utility Model Registration] (1) In a magnet-driven multiple magnet-driven pump that operates a plurality of pump sections by rotational drive of a drive motor, the pump section includes a pump casing forming a pump chamber; a disc-shaped drive rotor having an annular drive magnet on its peripheral edge and rotationally driven by the drive shaft of the drive motor; 1. A multiple magnet-driven pump comprising: a disk-shaped driven rotor having a corresponding driven magnet; and a disc-shaped driven rotor that rotates as the drive rotor rotates to rotate an impeller. (2) The multiple magnet drive pump according to claim 1, wherein the driving rotor and the driven rotor rotate about the same axis of the drive shaft of the drive motor. (3) The pump casing includes a main casing having a shaft hole through which the drive shaft is inserted, a bearing portion on the outer periphery of the shaft hole that supports rotation of the driven rotor, and a liquid-tight state with respect to the main casing. A multiple magnet-driven pump according to claim 1, which is constituted in a unit shape by a cover casing assembled to a casing. (4) The multiple magnet drive pump according to claim 1, wherein a plurality of the pump parts are arranged in the axial direction of the drive shaft.
