MD 1C

VACUUBRAND696600ca. 175 mmca. 143 mmca. 6.9 kg

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
