XDS dry scroll pumps

XDS dry scroll pumps have become industry standard when dry pumping is essential, proving to be a robust and clean vacuum pump solution in a range of applications. Now, 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.

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 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.
