Edwards nXDS20iC 16.5 cfm Chemical−Resistant Dry'scroll Pump

SKU nXDS20i Categories ,

Features and Benefits

  • Chemical and corrosion resistant with Chemraz ® internal valves and stainless steel fittings for extra protection from the pumped media
  • Lubricant−free within the vacuum envelope and hermetically sealed means totally clean and dry vacuum to prevent cross contamination
  • No atmosphere to vacuum shaft seals means bearings are completely isolated, which prevents processttack and means the bearings run cooler and last longer
  • Simple single sided scroll arrangement combined with an innovative motor and bearing design allows for easy field service with a minimum of special tooling for low cost of ownership and maximum up−time
  • Improved motor and drive efficiencies for reduced power and cost of ownership
  • Advanced interface provides a variety of traditional, analogue and digital control methods enabling remote control/monitoring via USB, RS232 or RS485
  • One year warranty, as well as technical support from Edwards
