Edwards XDS35iC 25cfm Chemical-Resistant Scroll Pump w/ silencer

Regular price $10,932.70

The XDS35i pump has an innovative bearing shield that isolates the vacuum environment from all forms of lubricant, making it not only lubricant-free but hermetically sealed. XDS35iNGB variant has had the gas ballast feature removed for applications such as rare gas recirculation and gas recovery. 

The XDS46i shares many of the same features of the XDS35i but with a peak speed of 40 m3h-1. The pump has been optimised for maximum pumping speed at inlet pressures between 1 mbar and 10 mbar, making it ideally suited for LCMS and ICPMS applications requiring higher pumping speeds. 

The C variant has been modified so that it is more suitable for use on vapour handling processes and may be used in some applications using corrosive substances. The C version is fitted with Chemraz® internal valve pads and stainless steel exhaust port.

Features and benefits

• 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.
