VACUUBRAND, Inc. Chemical-Resistant Diaphragm VacuumPump - 1.5 mbar 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 down to 1.5 mbar. 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 a good choice when working with larger volumes of condensable vapors (high boiling point solvents) due to the higher pumping speeds and very good ultimate vacuum (even with gas ballast). The new NT-series features further improve performance data and superior vapor tolerance. This is our most popular pump for larger applications with low boiling-point solvents,a nd is the heart of a family of pumping units.
