The XDS35i family of scroll pumps offers proven dry, clean vacuum solutions for a wide range of applications, with smart drive technology to look after the pump and provide worldwide performance.
Now, a combination of the 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 and XDS35i Enhanced pumps are available as standard pumps with gas ballast, versions of the pump with no Gas Ballast (well suited for rare gas recirculation and gas recovery applications) and the C versions of the pumps featuring Chemraz® internal valves and stainless steel fittings for extra protection from the pumped media.

Features & Benefits 
 

• Bearing shield - ensures separation between process gases and bearing lubrication to ensure a 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 feature - 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.
  
  
• Take another step - the Enhanced versions offer up to 20% lower peak power requirements during initial pump down which means it has the ability to pump down large volume chambers with no loss of performance and has up to 25% more pumping speed at these roughing pressures which helps on higher frequency cycling applications as well
