MV 2 NTDiaphragm pump
Overview
- contamination-free pumping and evacuation
- high flow rate even near ultimate vacuum
- outstanding ultimate vacuum
- whisper quiet and ultra-low vibration
- exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs
Ultimate vacuum
0.5 mbar
Max. pumping speed 50 Hz
2.2 m3/h
Diaphragm pump in action
Four-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases when the need is to reach fractional millibar ultimate vacuums. All parts in contact with pumped vapors or gases are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of non-corrosive applications. The new NT-series pumps provide whisper-quiet and ultra-low-vibration operation, high leak-tightness and improved vacuum. The highly flexible, fabric-reinforced double diaphragm made of FKM offers extended operating life. Four-stage diaphragm pumps are an excellent choice for continuous, contamination-free evacuation and pumping of non-aggressive gases under the very high vacuum demands of applications in physics and analytics. Due to the outstanding ultimate vacuum, these pumps are often used as alternative to rotary vane pumps. A typical application is the use as backing pump for turbomolecular drag pumps.
