Edwards Enhanced XDS35iC Dry Scroll Pump | 100-120/200-230V 1PH 50/60Hz  | A73008983


  • (PN): A73008983

The Edwards Enhanced XDS35iC Dry Scroll Pump proves to be a robust and clean vacuum pump solution in a range of applications and processes.

This Edwards Corrosive Version (C) XDS35iC has been modified so that it is more suitable for use on vapor handling processes and may be used in some applications using corrosive substances. The C version is fitted with Chemraz internal valve pads and stainless steel exhaust port.

The XDS35iC Oil-Free Dry Scroll Vacuum Pump has a patented bearing shield designed to isolate the vacuum environment from all forms of lubricant. This feature ensures that the bearing remains totally dry, as well as protecting it from any process gases. The adjustable gas ballast allows vapor to be handled and opens up the range of applications to many that were previously unsuited to scroll pumps.

The Edward XDS35iC pump is optimized for maximum pumping speed at inlet pressures between 1 mbar and 10 mbar making it ideally suited for LCMS and ICPMS applications. Recent improvements in tip seal technology have lead to reduced tip seal wear therefore giving a longer time between service interventions. Pumping displacement for this pump is 25 CFM at 60hz.

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 vapors including water vapor 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.


Scroll pumps use intermeshing fixed and orbital scrolls to form non-contacting, crescent shaped gas pockets that are continuously compressed by the orbiting action. This means that, unlike oil-sealed rotary pumps, there is no sealant or lubricant required in the swept volume of the pump.
