PRODUCT DATA SHEET 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. 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 m3h-1. 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. 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. Axial air gap motor reduces overall pump size and gives low power and noise. Simple single sided scroll design allows maintenance to be done in minutes for low cost of ownership and maximum up-time.

(1) measured as total pressure (2) These pumps are designed to pump down from atmospheric pressure, but prolonged operation at inlet pressures higher than specified may reduce bearing life. (3) for UK 240 V use 13 A fuse
