Your safety isassured because the pumps, including the non-metallic range, have all reached stringent ATEX standards. Verderair air diaphragm pump applications include brewing, paint, chemical and automotive industries.

Working principle
Air operated diaphragm pumps are reciprocating pumps where the working elements are flexible diaphragms. The drive is by means of compressed air acting directly upon the diaphragm. Another possibility is hydraulic drive instead of compressed air. The design uses at least two valves, one on the discharge and one on the suction side. Several types of valves are used, the most popular valves are flap, cylindrical and ball valves.
