Four-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases when the need is to reach fractional millibar ultimate vacuums. All parts in contact with pumped vapors or gases are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of non-corrosive applications. These pumps provide the advantageous combination of high pumping speed with an extraordinary good ultimate vacuum down to 0.5 mbar. The highly flexible, fabric-reinforced double diaphragms made of FKM offer extended operating life. Eight-cylinder NT pumps features quiet operation, smooth and easy to clean surfaces.
