<p>A rotary diaphragm fluid pump includes a rigid tubular body (1) with internal annular groove (2), a tubular flexible diaphragm (3) whose central portion is caused to orbit by an eccentrically driven bearing (5). Preferably the diaphragm is a moulding which features an elastic fixed abutment (11, Figs. 2 & 3) between the inlet and outlet ports, and internal reinforcement (4) to ensure that the full diaphragm stroke is achieved. Two such pumps may compliment each other to produce a pulsation free output. <IMAGE></p> |
