Abstract: The centrifugal pump (1) includes several pump stages which are arranged axially between a head part (4) and a foot part (2). An outer casing (3) peripherally surrounds the pump stages. An axial end of the outer casing (3) is fastened on the head part and the other axial end of the outer casing (3) is fastened on the foot part. A mechanical connection between the head part (4) and the foot part (2) is formed by the outer casing (3).
