Scroll
pumps are an excellent alternative to rotary vane pumps where oil
free pumping is desirable. The XDS pumps in particular use an innovative
bearing shield to isolate the vacuum environment from all forms
of lubricant not only making them totally dry, but also protecting
the bearing from any process gases. Vapour handling is enabled
by an adjustable gas ballast; this allows the range of pumps to
satisfy many applications that were previously off limits to scroll
pumps.
