The XDS46i pump is a development on the XDS35i and thus shares many of the same features and benefits but with a peak speed boosted to 40m3/hr. The XDS46i is optimised for maximum pumping speed at inlet pressures between 1 mbar and 10 mbar making it ideally suited for LCMS and ICPMS applications requiring a higher pumping speed than that offered by the XDS35i.

Features and Benefits

  • Lubricant-free within the vacuum envelope and hermetically sealed means totally clean and dry vacuum to prevent cross contamination
  • No atmosphere to vacuum shaft seals means bearings are completely isolated, this prevents process attack and means bearings run cooler and last longer
  • No oil changes required eliminating costs of contaminated oil disposal
  • Simple single sided scroll design means maintenance is done in minutes for low cost of ownership and maximum up-time
  • Inverter drive for consistent pumping speed at 50/60Hz


  • LCMS inlet
  • ICPMS inlet
  • Coating
