Abstract

1,081,164. Centrifugal pumps. U. M. W. BARSKE and W. MURRAY. Aug. 4, 1964 [July 19, 1963], No. 56061/66. Divided out of 1, 081, 163. Heading F1C. In a centrifugal pump having an impeller 33a which discharges substantially tangentially into a chamber 31 around the impeller periphery (see, e. g., Specification 1,081, 163), at least one diffuser insert 40 is disposed tangentially to the outer region of the chamber with its inlet end 41 projecting into the chamber. Preferably, a streamlining fillet 43 is provided.
