The XDS pumps are an innovative design which use a bearing shield to isolate the vacuum environment from all forms of lubricant, not only making it totally dry, but hermetically sealed. The shield also protects the bearing from any process vapours.
 
Gas ballast allows vapour to be handled and opens up the range of applications to many that were previously unsuited to scroll pumps. The XDS10 pump is designed as a dry option for general laboratory applications including backing turbo pumps. It is also used with electron microscopes and mass spectrometers. 

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.

• Lubricant-free within the vacuum envelope and hermetically sealed means totally clean and dry vacuum to prevent cross contamination
• No atmosphere to vacuum shaft seals means bearings are completely isolated, which prevents process attack and means the bearings run cooler and last longer
• No oil changes required eliminating costs of contaminated oil disposal
• Simple single sided scroll design means routine maintenance is done in minutes for low cost of ownership and maximum up-time
• Gas ballast feature to enable pumping of vapours
