High-Capacity Diaphragm Pumps

Complete dry pump for high vacuum applications
  • Unique flat diaphragm design reduces wear and tear for longer service life
  • Vacuum levels as low as 1.5 Torr
  • Very quiet operation at 44 dB(A)
Provides high flow rates for increased laboratory efficiency. Long service intervals reduce downtime. Choose a chemical-resistant pump if solvents or corrosive gases will come into contact with the pump. Gas ballast, which allows purging of any condensed gases in the pump, is standard on all models. Protect your pump with an inlet filter for particulates or use a cold trap for condensable vapor; see pages 2150 to 2153 for vacuum pump accessories.
