Membrane pump MD 4 NT

Three-stage diaphragm pumps are ideal for continuous, oil-free pumping of gases and achieve a very good final vacuum. 
The materials used, such as aluminum and selected plastics, open up a wide range of applications for non-aggressive gases. 
The new NT series offers particularly quiet and low-vibration operation, high gas tightness and improved performance data. 
The highly flexible FKM double membranes with fabric reinforcement ensure a very long membrane service life. 
Three-stage diaphragm pumps are ideal for continuous, oil-free evacuation and pumping out of non-aggressive gases with high vacuum requirements such as in physics and analytics. 
Thanks to their very good ultimate vacuum, these pumps can often replace rotary vane pumps. 
Typical applications are the degassing of viscous media and in particular as a backing pump for turbomolecular drag pumps.
