ROBUST MEMBRANE PUMP WITH HIGH EFFICIENCY
Verderair VA25 (HE) in plastic
VA25 (HE)Highly efficient,air-operated diaphragm pumps are suitable for a wide range of applications in many different industries.The reliability of this pump series can largely be attributed to the innovative air distribution valves developed based on many years of experience.This series is suitable for small container transfer/drainage or as a basic dosing pump.The pumps are available with pump housings/manifolds in 3 different materials and diaphragms/balls in 8 and 9 different materials, respectively.Due to the great flexibility in material selection, the optimal solution for the application can always be found.
