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 applications that require more than just transporting liquids. Also very sticky and viscous liquids, or liquids containing solids can be handled without problems. The quick acting air valve technology is making the VA, VA PURE and the VA HI-CLEAN the most efficient diaphragm pump series on the market.
