Traditional turbomolecular pump rotors either delivered high speed or high compression. The nEXT rotor on the other hand, eliminates that compromise through its re-designed blade arrangements for exceptional pump performance for a pump it’s size and achieve both higher speeds and compression.
Edwards is the leading producer of turbomolecular pumps in the world. Our industry standard STP pumps for magnetically levitated turbomolecular pumps are the most demanded in the challenging semiconductor applications. The EXT and nEXT are at an equal level of demand and have become an industry standard in many of the analytical instruments and R&D establishments over the last 20 years, making it close to 200,000 pumps in the field.
Our solid reputation for our turbomolecular pumps in the field of analytical manufacturers in the world has been quite rewarding. When you buy an Edwards nEXT turbomolecular pump, reliability is guaranteed, based on field proven technology and also user serviceability in just minutes!
In a traditional turbomolecular pump, there is an increase in vibration levels because the bearing is supported axially and radially by damping elastomers that eventually damp the rotor vibration.
Whereas, in the Edwards nEXT turbomolecular pump, there are lower vibration levels for the lifetime of the pump. This is due to the lower bearing being hard mounted into a special suspension system that eliminates damping elastomers. This special suspension system is intended to be stuff in the axial direction that ensures precise rotor positioning, but also more compliant radially that eventually absorbs vibration.
The end user serviceability is facilitated while changing the pump bearing because it does not require to be re-balanced and can be done without the use of complex tooling, jigs, fixtures or major disassembly.
- Low cost of ownership – user serviceability
- Reduced time – no customs paperwork or health & safety forms to complete
- Increased up time – no shipping product for service
Flexibility and customization are the main features kept in mind while developing the nEXT range of pumps. This has helped us to cater to the growing needs and challenges faced for various applications, by utilizing the extensive knowledge we have in the field and providing tailored solutions. Splitfow variants are also available to suite a larger array of uses.

STP Maglev Turbomolecular Vacuum Pumps
For a consistent, reliable performance and zero maintenance, you can rely on Edwards STP Maglev Turbomolecular Pumps to deliver every time. These are the primary option for applications that require high up-time, hydrocarbon-free pumping, minimal maintenance and reduced vibration. These are the sought-out option for applications that require reduced maintenance and vibration, hydrocarbon-free pumping and high up-time.
There is no contact between the rotor and the pump because it is entirely suspended using magnetic bearings. This not only reduces the vibration levels but also reduces level of maintenance because there isn’t any contact with the bearing when the rotor is rotated. An energy saving protocol has also been included in each design so as to ensure efficiency in power consumption without a compromise on quality or performance of the pump. The first STP Maglev Turbomolecular Pump was sold in 1983, and currently world-wide we have over 130,000 installations from which 85% run on semiconductor process tools where they show incredible levels of operation.
