Vacuubrand Diaphragm Pump MD 12 NT


Vacuubrand Diaphragm Pump MD 12 NT

The oil-free dry compression MD 12 NT diaphragm pump is a particularly powerful pump for the evacuation and transport of non-aggressive gases. The three-stage design of the eight-cylinder pump allows an especially advantageous combination of high pumping speed with a very good final vacuum.

Materials using aluminum and selected plastics (such as diaphragms and valves made of FKM) have a wide range of applications. A very long membrane life is achieved thanks to the highly flexible FKM double membranes with fabric reinforcement. Eight-cylinder NT pumps are characterized by high smoothness and smooth, easy-to-clean surfaces. Like all VACUUBRAND diaphragm pumps, they are not degreased and have no sliding parts on the media side, so they do not wear out completely during normal operation.

Performance features

  • 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
