Product description

35 m³/h oil-free pump with innovative bearing shield and adjustable gas ballast.

Edwards XDS35i Dry Scroll Pump

Ultimate Vacuum 1 x 10-2 mbar Inlet Connection NW40 Displacement 43 m3h-1 / 25 ft3min-1

Features

  • Scroll pumps provide oil-free pumping, making them an excellent alternative to rotary vane pumps for clean applications
  • The XDS pumps feature an innovative bearing shield that isolates the vacuum environment from lubricants, ensuring a totally dry operation and protecting bearings from process gases
  • Adjustable gas ballast enhances vapor handling, allowing the pumps to be used in applications previously unsuitable for scroll pumps
  • Achieves a peak pumping speed of 35 m³/h (50 or 60 Hz) for rapid and effective operation
  • Capable of handling a maximum inlet pressure for water vapor of 35 mbar (23 Torr)
  • Operates at a nominal rotation speed of 1750 rpm for consistent performance
  • Exceptional leak tightness of &lt;1 x 10⁻⁶ mbar ls⁻¹ for reliable and efficient operation

Edwards XDS35i Dry Scroll Pump Scroll pumps are an excellent alternative to rotary vane pumps where oil free pumping is desirable. The XDS pumps in particular 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. Vapour handling is enabled by an adjustable gas ballast; this allows the range of pumps to satisfy many applications that were previously off limits to other scroll pumps.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
