A magnetically-levitated centrifugal pump comprises a pump head section and a pump section, where the pump section comprises a stator, a torque transmission disc, a motor, a displacement sensor, and a pump housing.

Disposable magnetically-levitated centrifugal pump

A disposable centrifugal blood pump with magnetic coupling provides a centrifugal blood pump with magnetic coupling which is simple in structure of disposable parts with low cost. Therefore, a housing as the disposable part includes a rotor having pole faces extending on the outer-peripheral surface and projecting inward from the inner-peripheral surface and an impeller attached to the rotor, and a stator as a reusable part includes three or more electromagnets for electromagnetic coupling for forming a magnetic coupling between the stator and the rotor, a torque transmission disk formed by sandwiching a ring-shaped permanent magnet between two upper and lower ring members and having pole faces corresponding to the pole faces projecting from the inner-peripheral surface of the rotor formed to project for generating a magnetic coupling between stator and rotor, a motor for rotating the torque transmission disk, and a displacement gauge for measuring displacement of the rotor.
