Abstract

The invention relates to hydraulic machines, in particular to pumps that may be used for pumping liquids.The multistage centrifugal pump includes a housing (1), made of sections separated by intermediate discs (6), each section is provided with a rotor (2), mounted on a drive shaft, passing through the housing with the possibility of axial movement and including a driving disk (4) and a driven disk (5), closure elements, chambers and inlet and outlet covers, pipe bends (7) with liners (8). Each section is provided with a hydrodynamic bearing (10), which comprises an operating disc (11), on one surface of which are made grooves (12), and a counterbody (13), made in the form of a disk, proportional to the operating disc (11) with which form the friction pair, at the same time the operating disc (11) abuts against the intermediate disk (6), and the counterbody (13) - against the coating surface of the driving disc (4) of the rotor (2).
