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