Four-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases when the need is to reach fractional millibar ultimate vacuum. 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 extraordinarily good ultimate vacuum down to 0.5 mbar, and down to 0.3 mbar with the VARIO® version with self-adapting motor speed control. The highly flexible, fabric-reinforced double diaphragm made of FKM offers extended operating life. The VARIO® system consists of the VARIO® pump and the CVC 3000 vacuum controller with external gauge head. It provides precise vacuum control, higher pumping speed and improved ultimate vacuum. Eight-cylinder NT pumps feature quiet operation, with smooth and easy-to-clean surfaces.
