Air-operated diaphragm pumps (also known and pneumatic double-diaphragm pumps) are self-priming, positive-displacement pumps that use a reciprocating mechanism of diaphragms and ball-check valves to create suction. The pumps are actuated by compressed air, eliminating the complexities of electric motors and shafts. As a result, diaphragm pumps are intrinsically safe and applicable in various hazardous areas.
Thanks to its simplified construction and durable materials, a diaphragm pump is one of the most robust and reliable choices for aggressive and corrosive applications in the chemical and petroleum industries. With several material options available, our pumps can match practically any possible product and process. For the most hazardous applications, we offer a range of pumps rated for ATEX Zone 1.
In addition, we offer hygienic diaphragm pumps for applications in the food and beverage industries. The large passage and the gentle action of the diaphragms make them ideal for delicate or viscous food products, as well as liquids with suspended solids.
