Edwards XDS dry scroll pumps

Edwards XDS dry scroll pump have become industry standard when dry pumping is essential, proving to be a robust and clean vacuum pump solution in a range of applications with pumping speeds up to 40 m3h-1.

Let us help you find the right product from this series

Product features

  • Bearing shield: ensures separation between process gases and bearing lubrication to ensure clean vacuum and no possibility of contamination to lubrication from process gases, which prolongs bearing life.
  • Smart motor drive: means consistent performance globally, pump overload protection and remote start/stop capability.
  • High flow gas ballast: allows pumping of vapours including water vapour at up to 240 gh-1.
  • Simple single sided scroll design: allows maintenance to be done in minutes for low cost of ownership and maximum up-time
  • Genuine spare-parts support → helps reduce unplanned downtime risk
  • Industrial-duty construction → supports repeatable operation under sustained loads
  • Verified technical documentation → enables model selection against actual process requirements
  • AxFlow product-selection support → helps align pump, controls and accessories with the application
  • Maintenance and service support → helps protect process continuity over the equipment lifecycle
  • Application-specific configuration → helps avoid oversizing, undersizing and unnecessary operating cost

Product description

A combination of the patented double start scroll form technology and by-pass valves have enabled Edwards to offer the XDS35i Enhanced range of pumps to complement our original family.

XDS35i incorporates smart drive technology to look after the pump and provide worldwide performance.

With reduced peak power requirements at roughing pressures and continuous higher roughing speeds, these enhanced pumps enable the user to address the performance envelope to help with those special applications where roughing performance or the ability to evacuate a large chamber volume is important.

The enhanced versions offer up to 20% lower peak power requirements during initial pump down: meaning it has the ability to pump down large volume chambers with no loss of performance.

It has up to 25% more pumping speed at these roughing pressures, which helps on higher frequency cycling applications as well.


Edwards XDS is used for laboratorijoms, moksliniams, analizės ir švariems pramoniniams procesams. It should be selected around the required vacuum level, gas load and process conditions. The exact configuration depends on the application.
Edwards XDS is based on alyvos nenaudojantis spiralinis mechanizmas su izoliuotu guolių mazgu. This technology creates or supports the vacuum required by the process. Performance must be checked against the selected model and operating point.
Check pumping speed, working and ultimate pressure, gas composition, temperature, cooling and connections. Verified product information includes XDS35i iki 35 m³/h ir 0,01 mbar; XDS46i iki 40 m³/h ir 0,05 mbar. AxFlow can help compare these requirements with the available Edwards configurations.
Maintenance depends on the technology, operating hours and process contamination. Follow Edwards service instructions and use the correct consumables and spare parts. Preventive maintenance helps reduce unplanned downtime.
AxFlow can support product selection for Edwards XDS and help identify the appropriate configuration. AxFlow also provides service and spare-parts support for installed equipment. Contact AxFlow for availability and a quote.
