The Edwards nXDS10i is the next generation in completely oil free, dry scroll pumps and replaces the Edwards XDS10. Edwards nXDS10i improves on legacy XDS series pumps by offering increased pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise. Gas ballast allows for pumping of condensable vapours including, water, solvents, dilute acids and bases. Edwards nXDS10i pumps also feature the latest in tip seal technology giving significantly longer life between tip seal changes. Integrated inverter drive with auto sensing voltage input delivers optimized pumping performance globally. Edwards nXDS10i pumps are designed to be completely field serviceable.

Features & Benefits

  • Lubricant-free within the vacuum envelope and hermetically sealed means totally clean and dry vacuum to prevent cross contamination
  • Thermally controlled fan for reduced noise
  • No atmosphere to vacuum shaft seals means bearing are completely isolated, which prevents process attack and means the bearings run cooler and last longer
  • Simple single sided scroll arrangement combined with an innovative motor and bearing design allows for easy field service with a minimum of special tooling for low cost of ownership and maximum up-time Improved motor and drive efficiencies for reduced power and cost of ownership
  • Advanced interface provides a variety of traditional, analogue and digital control methods enabling remote control/monitoring via USB, RS232 or RS485


  • General clean pumping applications
  • Scanning Electron Microscopes - SEM Beam lines and high energy physics
  • Mass Spectrometry-Electron Microscopy
