Edwards Vacuum nXDS6 Scroll Pumps
Features and Benefits
Advanced scroll-form and tip-seal technologies deliver best‑in-class vacuum performance and unrivalled ultimate vacuum levels.
Unique tip seal design significantly reduces wear to minimise maintenance and extend service life.
Quiet operation with typical noise during operation < 52 dB(A) for minimal environmental impact.
Advanced interface providing a variety of traditional and analogue and digital control methods enabling remote control/monitoring via RS232 or RS485.
Integrated inverter drive with auto sensing input delivers optimised pumping performance globally.
Pump range includes 6, 10, 15 and 20 m3h-1
With exceptional pumping capability, ultimate vacuum performance and state-of-the-art design features Edwards nXDS is the best performing pump in its class.
nXDS improves on legacy XDS pumps by offering increased pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise - up to 20 times quieter than other pumps. Gas ballast allows for pumping of condensable vapours 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 optimised pumping performance globally.
nXDS pumps are designed to be completely field serviceable. 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.
