High-Vacuum Pumps for Corrosive Gases

  • Corrosion-resistant parts—ideal for pumping corrosive gases such as Cl2, HBr, F3CCO2H, and HOAC
  • Pumps draw clean oil from top of oil reservoir, not from the bottom as do direct-drive pumps
  • Large oil reservoir dilutes contaminants
  • Lower pump speed (less than 580 rpm) results in less wear, cooler operation, and longer service life
  • Bubbler tube in the oil reservoir allows nitrogen gas purging, resulting in lower operating temperature, reduced corrosion rate, and extended pump oil life
Pumps include a clamp, centering ring, NW flange to hose barb fitting, pump oil, and an instruction manual containing an applications booklet.
