Four-stage diaphragm pumps - like the MV 2 VARIO select - are an excellent solution for continuous, oil-free pumping of non-corrosive gases at fractional millibar vacuum levels. Wetted parts are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of non-corrosive applications. The MV 2 VARIO select continuously adapts its motor speed to hold the desired vacuum level. That means the pump is whisper-quiet and generates ultra-low vibrations, and has high leak tightness. The highly flexible fabric-reinforced double FKM diaphragm is ideal for extended operating life. The VARIO® design includes the variable speed pump and the VACUU·SELECT vacuum controller with an external gauge head. The demand-responsive motor speed control on VARIO® models further extends the already long lifetimes of diaphragms and valves.
