Abstract: The invention relates to a pump for moving blood and other shear-sensitive with a rotor journaled hydraulically and, if necessary, magnetically in a housing and where the rotor (1) has flow-control surfaces (2, 4, 35, 33, 37, 41) for producing centrifugal flow components (3) and flow components (4) directed against the housing (30), the centrifugal flow components (3) serving mainly for producing the externally effective throughput and the flow components (5) directed against the housing serving mainly for contact-free journaling and stabilizing of the rotor in the housing.

Abstract: The invention relates to a centrifugal pump comprising a pump head (1) and a drive (2) for delivering blood and other ?-sensitive fluids, such as cell-containing cleaning suspensions, for example, in blood-cleaning units, wherein the drive (2) has a drive rotor (64) with a rotor disk (8) which is provided with permanent magnets (7) which are assigned permanent magnets (33), fitted on the pump rotor (3), for the purpose of magnetic coupling, and are assigned in the drive to the magnetic coils (4) of a stator for the purpose of generating the rotary movement, and wherein the pump rotor axis (61) extends into the pump intake (11) and is magnetically centered in the pump intake (11).
