Abstract

228,365. British Electric Plant Co., Ltd., and Maudling, A. W. Feb. 26, 1924. Multi-stage pumps; casings.-The diffusion ring A of a centrifugal pump has continuous guide passages B which gradually increase in cross sectional area from inlet end to outlet; the first part of each passage is bounded by the circumference of the impeller C and a stationary wall F diverging therefrom, then the passage forms an out-turned oblique spiral though the diffusion ring. An in-turned spiral E defined by walls cast on the diaphragm D leads to the eye of the next impeller. The passages may be arranged to lap over each other.
