The XDS100B is a scroll booster, with a pumping mechanism designed specifically to delivery high pumping speeds.

Like all booster pumps it needs to be used in conjunction with a primary pump and is ideally matched with Edwards XDS35i or XDS46i dry scroll pumps. The pump has been optimised for maximum pumping speed at inlet pressures between 1 mbar and 10 mbar.


• 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 changes 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.
