Abstract

1334089 Rotary positive-displacement pumps ENVIRONMENT/ONE CORP 24 Aug 1971 [31 Aug 1970] 39591/71 Heading F1F In a Moineau pump the stator 16 is connected to a casing 1 of iron, aluminium or P.V.C. by a resilient annular wall 14 of e.g. rubber, the casing having a liner 20 of anti-friction material, e.g. nylon, PTFE or stainless steel. The casing 1 has an inwardly directed flange 8 at the inlet end 2 forming an arcuate surface 18 over which the liner 20 extends to protect the end 15 of the wall 14.
