Edwards Shaft, Y is the central component of a pump rotor and carries the impellers, the shaft sleeves, the bearings, in some cases balance discs or drums and the coupling as well as other components that are part of the rotor. A shaft is designed to centre the rotating components on the pump rotor within the bores of the pump casing in such a way that the former do not touch the latter when the pump is running, taking shaft deflection into account. It is necessary to keep the radial distance between pump rotor and pump casing, i.e. the clearance gap, as small as possible in order to reduce the flow losses and the leakage rate.
