An air driven diaphragm pump having two opposed pumping cavities (26). A center section assembly (104) between the pumping cavities includes a cylinder (108) and a power amplifier piston (124). The power amplifier piston as well as the diaphragms (88) are coupled with a common control shaft (116). A valve assembly (138, 144) is arranged with a manifold (162) to receive pressurized air and distribute that air in alternating fashion to the sides of the power amplifier piston as well as to each of the diaphragms. By directing pressure to a side of the power amplifier piston facing the same direction as the diaphragm receiving pressure, an amplified pressure on a pump chamber is experienced. With the power amplifier piston being approximately twice as large as the diaphragm assembly an amplification of three times the pressure on the pump chamber is experienced. Both pump chambers are able to operate to pump material.
Pompe à membrane entraînée pneumatiquement et possédant deux cavités de pompage (26) opposées. Un ensemble central (104) entre les cavités de pompage comprend un cylindre (108) et un piston amplificateur de puissance (124). Ce piston, ainsi que les membranes (88), sont accouplés à un arbre de commande commun (116). Un ensemble soupape (138, 144) comporte un collecteur (162) servant à recevoir de l'air sous pression et à distribuer cet air de façon alternative aux côtés du piston amplificateur de puissance, ainsi qu'à chacune des membranes. On obtient une pression amplifiée sur une chambre de pompe en dirigeant la pression vers un côté du piston amplificateur de puissance tourné dans le même sens que la membrane recevant la pression. Le piston amplificateur de puissance étant approximativement deux fois plus grand que l'ensemble membrane, on obtient une amplification égale à trois fois la pression exercée sur la chambre de pompe. Les deux chambres de pompe sont capables de fonctionner afin de pomper un matériau.
