Welch Shaft, Part# 412093

Welch Pump Shaft is the central component of a centrifugal 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. The pump 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. It has used as in Air Compressor Replacement Shaft. Welch Shaft is used on Chemstar, Duoseal Pump models 1402N, 1402 and have a Part# 412093.
