The Verderair CONT EX air operated diaphragm pump is made of conductive polyethylene, standard ATEX certified and available in 4 sizes. Depending on the application, there is this air operated diaphragm pumps with ball valves (suitable for solids) or cylinder valves (higher suction lift).

Diaphragm Pumps

The Verderair diaphragm pumps are the best solution for transfer applications that require more than just fluid to be handled. The range is excellent for viscous or sticky media, slurry and solids. The Verderair diaphragm pump series offers diaphragm pumps, varying in material (metallic, non-metallic, conductive) to drive principle (electric, pneumatic). Applications are found in chemical industry, pharmaceutical industry, solar power industry, waste water treatment, ceramic slurry, and many more. Special models are available for ATEX, food and pharma applications.
