    摘要： A balancing arrangement which is used to relieve or take up axial thrust in a multistage centrifugal pump, having a balancing device with at least one axial gap (8) and at least one radial gap (6,7) and in which a balancing flow is conducted through the gaps, and having an axial bearing which receives remaining axial thrust. Associated with the axial bearing is a cardanic ring (10) which serves to offset alignment errors. Highly reliable operation with only low leakage losses is achieved by configuring the balancing device such that a residual thrust in the direction of the suction side of the pump exists in all operating conditons and the cardanic ring is designed such that it is elastically deformed by the residual thrust and has a spring constant such that the axial gap (s) will close from a maximum width position when the pump is at rest to a minimum width position during operation while still avoiding contact between the surfaces which define the axial gap.
