Diaphragm pump MZ 2 NT

Description

MZ 2 NT

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 and allow a wide range of applications for non corrosive gases. The two-stage construction provides the advantageous combination of high pumping speed and an ultimate vacuum down to 7 mbar. The highly flexible fabric-reinforced double diaphragm made of FKM is ideal for extended operating life. The new NT-series features further improved performance data.

Performance features

contamination-free pumping and evacuation
high flow rate even near ultimate vacuum
whisper quiet
