These oil-free diaphragm pumps are especially powerful pumps for evacuation and pumping of non aggressive gases. The one-stage design provides the advantageous combination of high pumping speed and low ultimate vacuum down to 70 mbar. All parts in contact with pumped media are made of aluminum and selected plastics allowing a wide range of applications for non-corrosive gases. It provides precise vacuum control and consists always of the pump and the VACUU·SELECT vacuum controller with external gauge head. The highly flexible, fabric-reinforced double diaphragm made of FKM offers extended operating life that increases significantly in motor speed controlled operation. The eight-cylinder pump ME 16 NT VARIO features exceptionally high pumping speed, low vibration and a very compact design with smooth and easy-to-clean surfaces.
