Edwards nXDS20iC 16.5 cfm Chemical-Resistant Dry Scroll Pump
The new nXDS-C pump is a modified version of the nXDS that is suitable for use on vapor handling processes, and may be used for some pumping applications involving corrosive substances. The nXDS-C variants have Chemraz® internal valves and stainless steel fittings for extra protection from the pumped media. Together with exceptional pumping capability, ultimate vacuum performance and state-of-the-art design features, the nXDS-C dry scroll pump is the best performing pump in its class.
The nXDS20iC is up to 20 times quieter than other pumps. Its intelligent control functions and up to five year service interval offer low cost of ownership, making it the small dry pump of choice for today’s most advanced technologies.
Free KF25 flexible stainless steel bellow (3.3 ft), clamps and centering rings ($219 value) included. Technical support and one year warranty covered by Edwards.
Edwards nXDS20i replaces the discontinued XDS20. Edwards made many big improvements, including chemical-resistant (C model), much longer service life, easier maintenance and better efficiency, to name just a few.
The Edwards nXDS20i and nXDS20iC pumps are truly dry vacuum pumps as all the bearings, with their hydrocarbon lubricant, are isolated from the vacuum space. The nXDS20i is the next generation in completely oil free, dry scroll pumps and replaces the XDS10. nXDS improves on legacy XDS pumps by offering increased pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise. Gas ballast allows for pumping of condensable vapors including, water, solvents, dilute acids and bases. nXDS pumps also feature the latest in tip seal technology giving significantly longer life between tip seal changes. Integrated inverter drive with auto sensing voltage input delivers optimized pumping performance globally. nXDS pumps are designed to be completely field serviceable.
