Description

Description
Diaphragm pumps are an excellent solution for continuous, oil-free evacuation and pumping of gases. All parts in contact with pumped media are made of aluminum and selected plastics, allowing a wide range of applications for non-corrosive gases. The one-stage construction provides the advantageous combination of high pumping speed and an ultimate vacuum down to 70 mbar. The highly flexible fabric-reinforced double diaphragm made of FKM is ideal for extended operating life. The NT-series features further improved performance data.

Performance features
contamination-free pumping and evacuation
high flow rate even near ultimate vacuum
whisper quiet
ME 4 NT with low vibration and higher pumping speed
exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs
