Description from the supplier

VACUUBRAND MD 12 NT Diaphragm Pump


Ultimate Vacuum
2 mbar (1.5 Torr)
Maximum Pumping Speed
7.1 CFM at 60Hz
Number of Heads/Stages
8/3

  • Contamination-free pumping and evacuation
  • High flow rate even near ultimate vacuum
  • Whisper quiet
  • Reduced process times
  • Exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs

The MD 12 NT diaphragm pump is an especially powerful pump for oil-free evacuation and pumping of non-aggressive gases. The three-stage design of this eight-cylinder pump provides the advantageous combination of very high pumping speed and excellent ultimate vacuum. The flow path consists of aluminum, stainless steel and carefully selected plastics to permit a wide range of applications. The fabric-reinforced double diaphragms are made of highly flexible FKM for extended operating life and high vacuum performance. Eight-cylinder NT pumps feature quiet operation, with smooth and easy-to-clean surfaces. Like all VACUUBRAND diaphragm pumps they operate absolutely oil-free and do not have any sliding components in the gas path. In normal operation they are completely free of abrasion. This eliminates most of the particulate impurities frequently generated inside of scroll or piston pumps.

The MD 12 NT is an excellent choice for continuous, oil-free evacuation and pumping of non-aggressive gases, especially for applications in physics and analytics. Due to the very good ultimate vacuum the MD 12 NT is often used as an alternative to rotary vane pumps, for example for vacuum ovens, for very quick and efficient degassing of viscous media, exhaust gas analytics and especially as backing pump for large turbomolecular drag pumps. The particularly high pumping speed enables the usage of bigger vacuum apparatus and with high gas throughput. The pump is extraordinarily silent and exhibits very low vibration making it an excellent choice for sensitive equipment such as electron microscopes. Back diffusion of oil or even oil back flow, e.g., into a high vacuum chamber is excluded due to its oil-free operation.
