Rotary vane vacuum pump XDS series

scrolldrysingle-stage

Scroll pumps are an excellent alternative to rotary vane pumps where oil free pumping is desirable. 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 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. 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
