Abstract (en)
[origin: WO9804834A1] The invention concerns a centrifugal pump, consisting of a pump head and a drive, for pumping blood and other shear-sensitive liquids, such as dialytic suspensions containing cells in haemodialysis equipment. It is characterized by the drive (2) having a drive rotor (64) with a rotor disk (8) that are provided with permanent drive magnets (7); permanent magnets (33) located on the pump rotor (3) being allocated to these for magnetic coupling, and to the magnetizing coils (4) of a stator in the drive for generating the rotary motion; and the pump rotor shaft (61) extending into the pump intake (11) and being magnetically centered in the pump intake (11).
