Vacuubrand 696613 MD 1C Chemistry Diaphragm Pump


The Vacuubrand MD 1C Three-stage chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet high requirements regarding ultimate vacuum. The three-stage construction provides the advantageous combination of high pumping speed and deep ultimate vacuum in a pump with a very small footprint. All parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms increase reliability and extend operating life. The MD 1C with gas ballast valve is optimally prepared for pumping easily condensable vapors (high boiling solvents).

Performance features:

    • outstanding chemical resistance and superior vapor tolerance

    • exceptionally high performance even at low vacuum

    • excellent ultimate vacuum even with gas ballast

    • whisper quiet and ultra-low vibration

    • proven long diaphragm life, maintenance-free drive system
