Pneumatic
pumps
Air-actuated double diaphragm pumps have long been recognized as the most flexible pumps in the industry for handling difficult liquids at relatively low pressures and flows. The range of applications is practically unlimited, almost any type of liquid can be pumped, from highly corrosive acids, high viscosity paints and adhesives, to food and beverage products

Working principle
1 Suction cycle
Compressed air fills the right internal chamber, thanks to the movement of the opposite diaphragm it creates, by lifting the ball of the lower valve, the suction of the incoming liquid. At the same time, the left chamber is in the "discharge" cycle

Air
2
Discharge cycle
Compressed air fills the left inner chamber, in the opposite chamber, lifting the ball of the upper valve, discharges the fluid. At the same time, the left chamber is in the “suction” cycle
