Abstract

The pump stage for a centrifugal pump comprises an impeller unit (10) having an axial hub and a diffuser unit (20) extended at a first face of said impeller unit (10). The impeller unit (10) is supported floating inside the diffuser unit (20). A shim ring (40) is associated with the impeller unit (10) and is sustained in sliding support on a washer (27) housed in a fixed position in a correspondent seat (26) of the diffuser unit (20) of an adjacent pump stage.
