Product Description

Utilize diaphragm vacuum technology for totally dry operation. There is no oil to change or monitor!


Diaphragm pumps are an excellent solution for continuous, oil-free evacuation and pumping of gases. All parts in these MZ 2 series pumps that are in contact with pumped media are made of aluminum, stainless steel and selected plastics, allowing 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 4 mbar. The highly flexible fabric-reinforced double diaphragms made of FKM provide high reliability and extended operating life. The NT-series features further improved performance data and compact design.

Performance Features:

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