XDS35i SCROLL PUMP 43.0M3/Hr

Scroll pumps are an excellent alternative to rotary vane pumps where oil free pumping is desirable. The XDS pumps, with pumping speeds of 35, 40 and 95 m3h-1, 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 other scroll pumps.

Description

• Lubricant-free within the vacuum envelope and hermetically sealed means a totally clean and dry vacuum to prevent cross contamination.
• No atmosphere to vacuum shaft seals means bearings are completely isolated, this prevents process attack and enable the bearings to run cooler and last longer.
• No oil to change eliminating cost of contaminated oil disposal.
• Simple single sided scroll design allows maintenance to be done in minutes for low cost of ownership and maximum up-time.
• Inverter drive for consistent pumping speeds worldwide.
