ABSTRACT:
A magnetically driven centrifugal pump comprising an impeller rotatably supported in a casing by means of a hollow shaft; passage means including the through hole of said hollow shaft for conducting part of a fluid so as to cool said shaft; and an auxiliary pump for forcing the fluid through said passage means, thereby preventing the shaft from being thermally seized or damaged even when the discharge pressure of the pump suddenly drops.
