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 has been designed to combine all the latest technological advances in turbomolecular pumps offering pump sizes of 55, 85, 240, 300, 400, 730, 925 and 1250 l/s pumping speeds for Nitrogen.
These pumps provide end-user serviceability and deliver a truly class leading product.
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.
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.
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. 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.
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.
