About this product

nEXT Turbomolecular pumps are hybrid bearing pumps with a compound drag stage and integrated controllers for pumping speeds from 47 to 1250 ls-1. They all feature a permanent magnetic upper bearing, which eliminates hydrocarbons at the top of the rotor and an oil lubricated lower bearing for reliable high speed operation. The on-board controller interfaces directly with our TIC and TAG controllers to provide low cost system integration. The nEXT models also allow user serviceability by way of a user changeable bearing cartridge for low cost of ownership. nEXT has been designed to combine all the latest technological advances in Turbomolecular pumps with some new thinking in design for manufacture, delivering a truly class leading product. The nEXT platform brings a high level of modularity to offer maximum flexibility for customer application and requirements. Each pump is available in different internal configurations to offer differing functionality and performance. Our nEXT pumps come in different variants "D" Duplex comes with both turbomolecular and drag stages for improved tolerance to higher backing line pressures. The “D” variants offer superior pumping speed and compression across all gas species. Triplex “T” variants feature turbomolecular, drag and Edwards unique regenerative pumping stages for the ultimate in compression ratio and boost technology for unique vacuum system rationalisation. The "H" variant has been physically tuned to offer an improvement where an application has focus on light gas compression. compression across all gas species.

Technical specifications

The nEXT55 and nEXT85 are the most compact pumps of the nEXT range with a 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 provide a high pumping density, greater than other pumps in its class, with almost double the pumping speed of similar sized turbo pumps. The rotor has been designed to optimise pump performance and achieve both higher speeds and higher compression while maintaining high levels of reliability and low risk to adoptors. As with all the pumps in the nEXT range field maintenance is only required every 4 years of operation, and this including replacement of the bearing can be performed by the end user. nEXT55 and nEXT85 bring with them the benefits in flexibility with comprehensive communication and control options available, as well as a full set of accessories, the ideal choice in deployable instruments or portable applications where a compact footprint or lower weight are key factors.
