  • Vacuum desiccation
  • Vacuum filtration
  • Vacuum degassing

XDD1 Dry Diaphragm Pumps

XDD1 Dry Diaphragm Pumps

XDD1 diaphragm pumps are used for backing small compound turbomolecular pumps in clean, high vacuum applications, and also designed to be free standing bench top units. A typical ultimate pressure of better than 5 x 10-8 mbar can be achieved when using an XDD1 to back a 70 ls-1 turbomolecular pump.

The 24 V version is designed to provide a complete pumping package using the Edwards

This version is suited to the customer who is building their own a system. The pump is a compact and efficient. Under normal conditions the XDD1 is virtually maintenance free, the lifetime of the diaphragms and valves is typically > 10,000 operating hours, depending on the application.

Features and Benefits
  • Dry pumping, lubricant free technology eliminating the need for costly oil changes and disposal
  • Lightweight and compact with a small footprint allowing flexibility of use
  • Ideal backing pump for small turbomolecular pumps
  • Complies with EN61010, EN1012, CSA/UL standards
  • Worldwide 115/230 V or 24 V options
  • IEC 60320 C14 connector on a.c. pumps
Applications
  • Residual gas analysis
  • Mass spectrometers
  • Cryostat and dewar evacuation
  • Ion pump evacuation
  • Surface science

nXDS Dry Scroll Pumps

Pompa membranowa dla przemysłu lekkiego - Edwards nXDS

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. nXDS improves on the original XDS pump technology by offering increased pumping speeds, combined with lower ultimate pressures, low power consumption and reduced noise. nXDS-C has been modified so that it is more suitable for use on vapour handling processes and may be used in some applications involving corrosive substances.

This chemically resistant version is fitted with Chemraz® internal valve pads and stainless steel fittings. nXDS dry scroll pumps can get peak pumping speed from 6,8 m3h-1 to 28,0 m3h-1 and ultimate vacuum from 0,03 mbar to 0,02 mbar.

Features and Benefits
  • Lubricant-free within the vacuum envelope and hermetically sealed means a totally clean and dry vacuum to prevent cross contamination
  • 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 operations < 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
Applications
  • Backing turbomolecular pumps
  • Chamber evacuation
  • Chemical applications including gel dryers and solvent recovery

XDS Dry Scroll Pumps

XDS Dry Scroll Pumps

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 XDS35i pump has an innovative bearing shield that isolates the vacuum environment from all forms of lubricant, making it not only lubricant-free but hermetically sealed. XDS35iNGB variant has had the gas ballast feature removed for applications such as rare gas recirculation and gas recovery.

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.

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 attaca 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
  • Pump range includes 35 and 40 m3h-1
Applications
  • Automotive; brake line and air conditioning evacuation
  • Backing turbomolecular pumps
  • Chemical applications including gel dryers and solvent recovery
  • Coating systems
  • High energy physics
  • Mass spectrometry
