The VA industrial range really does set the benchmark for air diaphragm pumps. The range features fast-acting air valve technology – eliminating wasted air and using all of the air for moving the fluid. The efficient use of air reduces the total amount of air consumption for a given quantity of fluid – reducing the energy cost. Available in metallic and non-metallic construction with many different wet-side materials, the VA range is compatible with chemically-aggressive and abrasive media. The range features bolted chambers for safe operation, rugged mountings to limit vibration.

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.
