MD 4C NT

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 of the MD 4C NT 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 also of high boiling solvents due to its very good ultimate vacuum (even with gas ballast). The new NT-series features further improved performance data, easy service and superior vapor tolerance.
