Abstract

A rotary positive displacement pump comprises a stator (1) with a clamping plate (6) and a base plate (3) with an annular surface (5) on the clamping plate (6)-facing side. A membrane (11) covering the annular surface (5) is held between the clamping plate (6) and base plate (3) and forms a pumping channel (12) extending from an inlet (13) to an outlet (15) between the membrane (11) and base plate (3). A powered rotor (2) running around the concentric axis (4) of the annular surface (5) has at least one roller (21) running around the rear face of a circle of individual pressure transfer elements (14) which press the membrane (11) onto the annular surface to progressively interrupt the path from inlet (13) to outlet (15). The annular surface (5) is a layer of a softer material than the base plate (3). Preferably, the soft material layer (5) is a silicone polymer with a 20-50 Shore hardness extending over the area covered by the pressure transfer elements (14) and is either cast, vulcanised or bonded into a recess in the base plate (3) so that it projects above the recess edges. The base plate (3) is made of a dimensionally stable plastic and is held between the fixed clamping plate (6) and a removable clamping plate (24).
