Edwards XDS Scroll Pumps

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.
