摘要 |
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. |
