Built on decades of experience

A turbomolecular pump is a multistage axial-flow turbine in which high speed rotating blades provide compression by increasing the probability of gas moving in the pumping direction. The turbomolecular pump is optimised for molecular flow conditions and requires a suitably sized backing pump to exhaust to atmosphere.   

nEXT turbomolecular pumps are drawing from our tried and trusted EXT and STP ranges. They offer superior performance, reliability, and end-user serviceability, setting the benchmark for scientific turbomolecular pumps.

Why select the nEXT?

  • Superior performance with exceptional pumping speeds and compression ratios
  • Proven reliability for peace of mind we have years of experience and a huge install base of turbopumps
  • Flexible solutions with bespoke design service available
  • Ease of use thanks to integrated intelligent controls
  • Extended lifetime and low cost of ownership: the pumps are fully end user serviceable
  • A large variety of standard variants for an enhanced customer choice

nEXT55 and nEXT85 turbomolecular pumps

The nEXT55 and nEXT85 are the most compact of the nEXT range, with significantly reduced height and improved performance in a smaller package these pumps offer pumping speeds of 55 l/s and 85 l/s for nitrogen.

They offer one of the highest pumping density of other pumps in its class, with almost double the pumping speed of similar sized turbo pumps.

nEXT240, nEXT300 and nEXT400 turbomolecular pumps

The nEXT240, nEXT300 and nEXT400 set the benchmark for scientific turbomolecular pumps, built on decades of experience and based on our tried and trusted EXT and STP ranges.

With these long established models we offer a wide variety of sizes and variants giving OEMs and end users a greater choice and the flexibility to tailor the most appropriate vacuum solution to meet their individual needs.

nEXT730, nEXT930 and nEXT1230 turbomolecular pumps

With the nEXT730, nEXT930 and nEXT1230, we have extended the range of our nEXT platform with three larger pumps offering speeds significantly over 730 l/s and 925 l/s and 1250 l/s for nitrogen. We have now taken these larger pumps a step further and can offer new high compression variants suitable for UHV applications and high throughput variants for harsh industrial applications.

These compact pumps are able to operate in any orientation* and are supported by a full range of accessories for cooling, venting, powering and control. As well as addressing the general R&D market, where faster pumping speeds are sometimes required, these pumps are also designed to meet the requirements of the coating market and other diffuse market sectors such as Heat treatment, Furnace applications, E-beam welding, Etch, Ion implant, Degassing and Cylinder evacuation.
