Dry Scroll Pumps

The great shape of high performance dry vacuum pumping

Edwards XDS and nXDS range of 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 with pumping speeds up to 40 m3h-1.

  • Take another step!

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 world-wide performance.

With reduced peak power requirements at roughing pressures and continuous higher roughing speeds: these pumps enable the user to address the performance envelope and 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.

The XDS benefits!

  • 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.

nXDS dry scroll pumps

Edwards nXDS15i dry scroll pump

Offering increased pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise levels than other pumps.

nXDS pumps are designed to be completely field serviceable.

Its intelligent control functions and up to five years service interval ensures low cost of ownership, making it the small dry pump of choice for today's most advanced technologies.

The onboard pump controller allows for:

  • Wide range voltage input with automatic selection,
  • Easy to use manual control buttons including a standby speed control button for efficient process tuning 
  • ... and for more convenient operation a remote control interface.

The nXDS takes scroll vacuum technology to the next level:

Improved performance, exceptional pumping capability, quiet operation and extended service intervals make nXDS the ultimate dry choice!

Why selecting the nXDS?

  • Quiet while in use: with low noise power level of 52 dB(A) the nXDS makes for a better work environment and low environmental impact.
  • Simple to operate: with intelligent and easy to use controls
  • No contamination and no oil to dispose of: the pumps are hermetically sealed for a lubricant and contamination-free vacuum
  • Low cost of ownership due to the comination of long service interval and low power consumption
  • Quicker process thanks to superior vapour handling, making the xXDS suitable to an even wider range of applications!
