ME 16 NT VARIO selectVARIO® diaphragm pump
Overview
- contamination-free pumping and evacuation
- high flow rate even near ultimate vacuum
- whisper quiet
- very low vibration
- exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs
Ultimate vacuum
70 mbar
Max. pumping speed 50 Hz
19 m3/h
VARIO® diaphragm pump in action
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. Large one-stage diaphragm pumps are an excellent choice for continuous, oil-free pumping of large amounts of gases. Typical applications are vacuum ovens and in general evacuation and pumping of non-corrosive gases. We recommend these pumps especially for processes with high inlet and process pressures. They are also excellent for very fast evacuations down to modest vacuum levels.
