A centrifugal pump has a gasket of the working wheel of the pump as removable movable ring, this is placed on the collar of the discs of the working wheel with fixation for rotation with it and with possibility of axial motion on it to support by fixed part of the pump and with needed pressing to it due to liquid pressure drop at its end surfaces. The support surface for the moving ring is arranged as a removable washer. The moving ring and the removable washer are made of antifriction one with respect to other materials. Such implementation increases stability and reliability of the pump in the process of its operation and improves its repair ability.
