Diaphragm vacuum pump MD 4 VARIO select

dry230VACthree-stage

This three-stage diaphragm pump is an excellent solution for continuous, oil-free pumping of non-corrosive gases to a vacuum level as deep as 1 mbar. All wetted parts are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of applications with non-corrosive gases. The MD 4 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 external gauge head. The demand-responsive motor speed control on VARIO models further extends the already long lifetimes of diaphragms and valves. Performance features VACUU·SELECT vacuum controller with graphical user interface and predefined applications simplifies work in the laboratory extraordinary diaphragm life for minimum operational and servicing costs contamination-free pumping and evacuation excellent ultimate vacuum and TURBO·MODE for use as backing pump for turbo pumps
