Abstract

322,120. Pearn, H. W., and Pearn & Co., Ltd., F. Dec. 24, 1928. Casings.-The impeller of a centrifugal pump has blades d, and is enclosed by a fixed diffuser having ducts g so formed that the liquid which is delivered by the impeller blades in the direction of the arrows h has its direction reversed by the curved ducts. The liquid passes from the ducts to the ports k for discharge; or in the case of a multi-stage pump it is guided to the eye of the next stage by vanes l, The ducts g are of progressively increasing cross sectional area, and they may contain longitudinal partitions p.
