Oil-Free Diaphragm Vacuum Pumps, Vacuubrand

Three-stage chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet even challenging requirements.

  • Three-stage design provides the advantageous combination of high pumping speed and very low ultimate vacuum
  • All parts of the diaphragm vacuum pump in contact with pumped media are made of chemically resistant fluoroplastics
  • Well-proven PTFE sandwich diaphragms provide increased reliability and extended operating life
  • All multistage pumps are equipped with a gas ballast to provide consistent pump performance with condensed vapors
  • Due to the gas ballast valve and its very good ultimate vacuum (even with gas ballast), the pump is also suitable for pumping condensable vapors of high-boiling solvents
  • Further improved performance data, easy service, and superior vapor tolerance

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 very low vibration
  • Long diaphragm life, maintenance-free drive system

NTRL approved.
