Edwards XDS46iC 35cfm Chemical-Resistant Scroll Pump w/ silencer

XDS scroll pumps have become industry standard when dry pumping is essential, proving to be a robust and clean vacuum pump solution in a range of applications and processes.

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.

Technology

Scroll pumps use intermeshing fixed and orbital scrolls to form non-contacting, crescent shaped gas pockets that are continuously compressed by the orbiting action. This means that, unlike oil-sealed rotary pumps, there is no sealant or lubricant required in the swept volume of the pump.

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.
