Abstract:

The present invention overcomes deficiencies in the prior art by providing a centrifugal pump which conforms to ANSI standards, is reversible, is efficient, is self priming, has low flow stability and low radial thrust characteristics, handles viscous fluids well, and can pump fluid within a high range of pressure values. Such a pump configuration provides an easy way to retrofit problem applications, an attractive cost effective solution for the new installations, and ensures dimensional interchangeability of the pump, for ease of replacement, spare parts inventory, and standardization of maintenance techniques.
