These new features enable them to be used on applications where the exposed standard fluoroelastomer valve pads may be affected by the media being pumped, and cause rapid deterioration. The XDS35iC and XDS45iC dry scroll pumps, with peak speeds of 35 and 40 m3h-1 respectively, can handle up to 240 grammes per hour of water vapour and are ideal in harsh processes including wet chemistry applications such as rotary evaporation and distillation processes.

The simple single sided scroll design allows routine maintenance to be done in minutes for maximum up-time. These dry scroll pumps provide an alternative to oil sealed rotary vane pumps and other dry technologies. It is lubricant free and hermetically sealed so it provides a totally clean and dry vacuum to prevent cross contamination.

Unlike other scroll pumps, the bearings in the XDS range are isolated by the bellows, so that any aggressive chemicals involved in the process will not attack them. The XDS35iC and XDS45iC extend the existing range of nXDS-C dry scroll pumps with pumping speeds from 6 to 40 m3h-1.
