ABSTRACT:
A centrifugal pump 10 having a centrifugal impeller 12 and a volute housing 56 for collecting flow discharged from the impeller is disclosed. Various construction details are developed which decrease stresses in the components and improve the efficiency of the construction. In one particular embodiment, the volute housing is formed inwardly of the pressure vessel 32 and has at least one sidewall 64 having a pressure region 58 bounded by the sidewall on the interior side of the pressure region and bounded by the outer pressure vessel on the exterior side of the pressure region to exert a pressure force on the sidewall under operative conditions.
