Description

This three-stage diaphragm pump is an powerful solution for continuous, oil-free pumping of non-corrosive gases to a vacuum level as deep as 1.5 mbar. With its high pumping speed, this pump is an excellent option for higher gas load applications or rapid pump down of vacuum chambers. 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 12 NT VARIO select automatically adapts its motor speed to hold the desired vacuum level. That also 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. And oil-free operation means that there is no risk of contamination from backstreaming. 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 high pumping speed and excellent ultimate vacuum and TURBO·MODE for use as backing pump for turbo pumps
