ABSTRACT OF THE DISCLOSURE A material handling device such as a pump, including a first housing part having an internal surface surrounded by a peripheral surface facing in generally the same direction as the internal surface. A substantially longitudinally inextensible flexible diaphragm has its periphery clamped on the first clamping surface by a co-operating second clamping surface of a second housing part 16 which carries a rotary member on which are mounted three rollers. A chamber is formed between the diaphragm and the internal surface. Upon rotation of the rotary member, the rollers sequentially urge the diaphragm onto the interal surface to form a constriction which traverses the chamber and moves the constriction from one port to another port formed in the first housing part. The configuration of the pump is such that as the rollers move sequentially over the diaphragm, the sum of the distances measured along the diaphragm between the clamping points of the diaphragm and the rollers adjacent thereto, remains substantially constant, thus allowing a substantially inextensible diaphragm to be used.
