Abstract

1425997 Liquid-ring pumps W JOHST 11 Feb 1974 [27 March 1973] 14578/73 Heading F1C In a liquid-ring pump comprising a helically bladed rotor eccentrically mounted in an elongate casing 19, the rotor hub 2 is of smaller diameter at the suction inlet end than at the discharge end and increases in diameter over a first portion 26 while over the remaining portion 27 it is of constant diameter as shown or increases in diameter at a rate less than over the portion 26. Blades 28, 29 acting on the liquid ring may be provided.
