VACUUBRAND MD 4 NT Diaphragm Pump

Ultimate Vacuum
1 mbar

Max. pumping speed at 60 Hz
2.5 cfm

Number of Heads/Stages
4/3

Features

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

These three-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of non-corrosive gases. They reach an excellent ultimate vacuum of 1 mbar. All parts in contact with pumped gases and vapors are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of applications with non-corrosive gases. The new NT-series provides whisper quiet and ultra-low vibration operation, high leak tightness and improved performance. The highly flexible fabric-reinforced double diaphragm made of FKM is ideal for extended operating life. These three-stage diaphragm pumps are an excellent choice for continuous, contamination-free evacuation and pumping of non-aggressive gases at demanding vacuum conditions. They are especially suitable for applications in physics and analytics. The low ultimate vacuum makes these an attractive alternative to rotary vane pumps in many applications. Typical uses are as backing pump for turbomolecular drag pumps, and for degassing of viscous media.
