XDSi Scroll Pumps

Edwards XDSi Scroll Pumps

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

The XDS35i pump has an innovative bearing shield that isolates the vacuum environment, making it not only lubricant-free but hermetically sealed.

XDS35i No Gas Ballast variant has had the gas ballast feature removed for applications such as rare gas recirculation and gas recovery. 

The XDS46i shares many of the same features of the XDS35i but with a peak speed of 40 m³/h. The pump has been optimised for maximum pumping speed at inlet pressures between 1 mbar and 10 mbar, making it well suited for backing turbomolecular pumps.

For more aggressive applications, ‘C’ variants are available which features Chemraz® internal valves and stainless steel fittings for extra protection from the pumped media.
