Abstract (en)

[origin: WO2017102491A1] The multi-stage centrifugal pump has a foot part (2) and a head part (9), between which pump stages are incorporated. The head part (9) and foot part (2) are connected via tie rods (11), which have one end secured on the head part (9) and the other end secured on the foot part (2). The tie rods (11), at one end, have a thread (14), by means of which they are braced on the head part (9). The tie rods (11) are formed from sheet metal and, at the other end, have a protrusion (31), by means of which they are secured on the foot part (2) in a form-fitting manner at least in the direction of tension (22).
