Turbomolecular Pumps Mechanical

Turbomolecular pumps (TMPs) are kinetic vacuum pumps which operate using a very fast spinning rotor (usually rotating at between 24,000 and 90,000 RPM). Their typical operating pressures are in the high to ultra-high pressure range between 10-3 and 10-11 mbar, employing pumping speeds of between 10 and 4,000 l/s. They are widely used in scientific and industrial applications that require precise and clean vacuum environments, such as surface analysis, mass spectrometry, and vacuum deposition. They can operate continuously for long periods, making them ideal for many laboratory and manufacturing applications.

nEXT Pumps

nEXT turbomolecular pumps are hybrid bearing pumps with integrated controllers for pumping speeds from 47 to 1250 ls-1.

 

The nEXT is a hybrid bearing compound turbomolecular pump. nEXT pumps combine our proven bearing technology, an improved rotor design with a new molecular drag stage to deliver improved pumping speed and compression ratios, and user serviceability. They feature 24 V to 48 V DC sensorless motors with a built-in drive that is fully compatible with our range of TAG and TIC controllers.

nEXT85

With nEXT85 and nEXT55 Edwards offers a small and compact turbomolecular pump platform ideal for Analytical Instruments as well as for the R&D market.

nEXT85H - NW40 NW16 - 80W

is a turbo molecular pump - hybrid bearing with a H - High Compression design ideal for light gas compression.

Features and Benefits

  • Upper magnetic bearing - ensures clean vacuum, low power and low vibration.
  • Optimised rotor designs - deliver high speeds and high compression.
  • Range of variants suitable for many applications - D = standard nEXT pump variant, H = optimised rotor design for high light gas compression and T = additional regenerative stage for increased compression and higher backing pressure capability
  • Integrated controller / electronics - offers direct I/O or serial control or can be connected to one of our TAG or TIC controllers for easy systemisation.
  • Fully user serviceable - oil cartridge and bearings can be changed in the field with minimal tooling.
  • Inlet screen - supplied as standard
