Material and geometry are two key factors in ideal mechanical performance of centrifugal-pump casings engaged in high pressures. This paper presents the model generation, static structural analysis, and geometrical modifications performed for a failed volute casing of a real centrifugal-pump. Failure would be examined under hydrostatic test conditions. Finite Element Method is employed in stage of theoretical problem investigation. To control failure phenomenon, necessary geometrical modifications are applied to the model. Geometrical modifications must have the least effect on hydraulic performance and avoid excessive manufacturing costs. Finally, some test volute casings with new geometry would be built to experimentally validate the analytical results and inspect the hydraulic performance. (C) 2009 Elsevier Ltd. All rights reserved.
