Abstract
A magnetically driven centrifugal pump comprises a split plate for dividing a space within a housing into two parts-impeller chamber and rotor chamber, a shaft supported by an inner wall of said rotor chamber and the split plate and having an internal rotor, an external rotor disposed outside the housing to magnetically drive the internal rotor, a passage means for permitting the communication between the impeller chamber and rotor chamber, and a restricting means for reducing the pressure of a fluid passing through said passage means.
