ME 4C NT

Description

ME 4C NT

Chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors. The one-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum down to 70 mbar. All major parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms for increased reliability and extended operating life. The new NT-series features further improved performance data and chemical resistance.

Performance features

outstanding chemical resistance
high performance even at low vacuum levels
whisper quiet
low vibration
long diaphragm life, maintenance-free drive system
