Edwards XDS10 Scroll Vacuum Pump


XDS10 Scroll Vacuum Pump

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 vapors.
Adjustable gas ballast allows vapor to be handled and opens up the range of applications to many that were previously unsuited to scroll pumps. The XDS pumps are designed for pumping condensable vapors and use materials selected for a wide range of laboratory wet chemistry applications.
