- very high flow rate even near ultimate vacuum
- quiet operation
- very low vibration
- exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs
Ultimate vacuum
70 mbar
Max. pumping speed 50 Hz
7.3 m3/h
Diaphragm pump in action
Diaphragm pumps are an excellent solution for continuous, oil-free evacuation and pumping of gases. All parts in contact with pumped media are made of aluminum and selected plastics, and allow a wide range of applications for non-corrosive gases. The highly flexible, fabric-reinforced double diaphragm made of FKM is ideal for extended operating life. These pumps with four heads provide very high pumping speed. The new NT-series features improved performance data. Large one-stage diaphragm pumps are an excellent choice for continuous, oil-free pumping of large amounts of gas- es. Typical applications are vacuum ovens and pumping of non-corrosive gases in general. We recommend these pumps especially for processes with high inlet and process pressures. They are excellent for very fast evacuations. The ME 8 NT offers very short evacuation times.
