The invention proposes a device for axial-thrust compensation for single- or multi-stage centrifugal pumps having closed impellers, which device can be made with little effort and which is therefore particularly suitable for retrofitting or correction in already existing centrifugal pumps. This is made possible by one or more pressure equalisation orifices (12) which open into the suction-side side space (10) of the impeller (2) and are connected to the discharge side (8, 9) of the centrifugal pump. <IMAGE>
