Abstract

A peristaltic pump (l) capable of compressing a flexible walled tube (9) between a pressure member (5) and a pressure plate (6).
In order for the force applied to the flexible walled tube (9) to be constant the pressure member (5) and pressure plate (6) are hydraulically biased together. In particular the pressure member (5) and pressure plate (6) are biased together by means of compressed air contained in a pressure chamber (7).
