XDS Scroll Pump

The XDS pumps are an innovative new design which use a patented 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.

Totally dry, lubricant-free vacuum

• No oils or greases of any kind
• Cleaner, more repeatable processes 
• No bearings or shaft seals in the pumping volume 
• No bearings to purge
  

Ease of maintenance

• No oil to buy, change or dispose of
• No re-greasing of bearings 
• No special tools, shims or jigs needed for service 
• Simple supply voltage selection
