FIELD: engines and pumps.
SUBSTANCE: invention relates to multi-stage centrifugal pump. Pump has support part (2) and head part (9), pump stages are built between them. Head part (9) and support part (2) are connected by tightening anchors (11). Anchors (11) are fixed by one end on head part (9), by the other end on support part (2). Tightening anchors (11) have thread (14) at one end to which they are attracted to head part (9). At other end (12) anchors (11) have at least one ledge (31), by which they are fixed in head part (9) or support part (2) at least in stretching direction (22) with geometrical closure. Tightening anchors (11) are formed at least in separate sections and made of sheet metal. So the lug formed by part (33) is made of sheet metal.
EFFECT: invention is aimed at improvement of the pump with respect to the tightening anchors and their attachment.
