Abstract

538,196. Centrifugal pumps. CHEW, Y. L. Jan. 23, 1940, No. 1375. [Class 110 (i)] A centrifugal pump comprises a back plate 9 and a one-piece casing 10 into which a driving shaft 7 enters at one side while a suction pipe 23 enters at the other side. The casing is secured to the back plate 9 by bolts 11 and plates 12, and has an opening 18 with a conical seating, through which the impeller 15 may be removed after it has been unscrewed from the shaft 7. The opening is closed by a flange 25 on an extension 24 of the suction pipe, and is held in place by a cover 19 sealed by a gasket 22, and secured to the back plate by bolts independent of the bolts 11. The impeller blades 31 may be detachably mounted on hollow bodies 30 carried by the impeller disc. To indicate internal wear, a hole 39 is formed in a thickened part 40 of the casing 10 extending only partly through 40, so that when the remaining solid portion of 40 has been worn away, water will escape through 39.
