ABSTRACT:
A multistage centrifugal pump for increasing the pressure of a product fluid passing through it. The pump includes a casing, an impeller shaft mounted for rotation within the casing and a plurality of impellers mounted back-to-back on the impeller shaft. A canned magnetic radial bearing is mounted around the outboard end of the impeller shaft and a magnetic thrust bearing and a magnetic radial bearing are mounted around the drive end of the impeller shaft. The pump is free of any product fluid return line connecting the product fluid chambers at the drive and outboard ends of the shaft.
