Premium dry vacuum Pump

6,850.00  plus VAT

With exceptional pumping capability, ultimate vacuum performance and state-of-the-art design features, the nXDS dry scroll pump is the best performing pump in its class.

The nXDS pumps use an innovative bearing shield to isolate the vacuum environment from all forms of lubricant not only making them totally dry, but also protecting the bearing from any process gases nXDS improves on the original XDS 5 and 10 pump technology by offering increased range of pumping speeds, combined with lower ultimate pressures, low power consumption and reduced noise.

The gas ballast allows for pumping of condensable vapours, including water, solvents, dilute acids and bases.

nXDS pumps feature the very latest in tip seal technology, giving a significantly longer life between tip seal changes.

Features and Benefits

Bearing shield ensures separation between process gases and bearing lubrication to ensure clean vacuum and no possibility of contamination to lubrication from process gases, which prolongs bearing life.

  • 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 smart drive – with auto sensing input delivers optimised pumping performance globally. 
  • Pump range – includes 6, 10, 15 and 20 m3h-1
