Abstract: In a magnetically driven pump so designed that a drive power of an electric motor is transmitted from a magnets-embedded drive rotor to a magnets-embedded follower rotor opposed to one another by way of a magnetic coupling, the follower rotor and an impeller are secured respectively to the opposite ends of a rotating shaft to which a thrust bearing of ceramic material is fastened for receiving an axial load, wherein a cushioning member is mounted on the rotating shaft so as to push the thrust bearing from the rear, in the position between the thrust bearing and a flange provided on the rotating shaft for determining the position of the follower rotor.
