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. 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.
Four-stage diaphragm pumps are an excellent choice for continuous, contamination-free evacuation and pumping of non-aggressive gases under the very high vacuum demands of applications in physics and analytics. They generate a clean vacuum, as they are designed without any contact seals, hence no abrasion or dust is produced that might creep back into the application. Due to the outstanding ultimate vacuum, these pumps are often used as alternative to rotary vane pumps
