Abstract : A control stator comprising a plurality of stationary vanes, ribs, or cavities is provided in a centrifugal pump having a shrouded impeller. The function of the control stator is to slow the swirl of fluid in the cavity between the casing and the impeller front shroud and thereby provide a very cost effective solution to the problem of excess axial thrust. The control stator is a simple, inexpensive non-rotating part that can be affixed in an existing space in the pump casing between the casing wall and the front shroud of the impeller
