<p>A centrifugal pump has static and closed housing/walling (1) for the feed liquid within the pump, and a contactless permanent-magnetic coaxial rotary coupling (6,7;13,14) for transmission of a drive torque within the pump housing. A pump impeller (4) forms an open unit with a magnet rotor (6). Between the magnet rotor (6) and a magnet driver (13) is a partitioning wall facing the opening of the pump drive-face, and the magnet driver (13) is mounted in at least one rolling bearing (16a; 16b) adjoining the pump.</p> |
