Vacuubrand Chemistry vacuum pump

NB.79

Three-stage chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet many difficult requirements. The three-stage construction provides the advantageous combination of high pumping speed and very low ultimate vacuum. All major parts in contact with pumped media are made of chemically resistant fluoroplastics.

Well-proven PTFE sandwich diaphragms provide increased reliability and extended operating life. The MD 4C NT with gas ballast valve is optimally prepared for pumping condensable vapors due to the very good ultimate vacuum (even with gas ballast) as well as for high boiling solvents. The new NT-series features further improve performance data and superior vapor tolerance.

• Pump supplied completely mounted, ready for use, with manual
• Outstanding chemical resistance and superior vapor tolerance
• Exceptionally high performance even at low vacuum
• Excellent ultimate vacuum even with gas ballast
• Max. backpressure 1.1 bar
• Whisper quiet and very low vibration
• Long diaphragm life, maintenance-free drive system
• IP40 rated protection
