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

Supplier: EDWARDS HIGH VACUUM METTLER

These XDS series pumps are completely oil free, dry scroll and improved on their pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise. Gas ballast allows for pumping of condensable vapours including water, solvents, dilute acids and bases. It also feature the latest in tip seal technology giving significantly longer life between tip seal changes. Comes with integrated inverter drive with auto sensing voltage input delivers optimised pumping performance. The pumps are completely field serviceable.
