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

With the nEXT730, nEXT930 and nEXT1230 Turbomolecular pumps Edwards provides larger pumps offering nitrogen pumping speeds of 730, 925 and 1250 l/s respectively. As well as addressing the general R&D market, where high pumping speeds are often 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. For our OEM customers, derivative versions of these products including split flow variants can be developed to match specific 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. The pumps feature bearings with a typical life time of at least 4 years with no maintenance. When required, a bearing replacement can be undertaken by the customer themselves or they can take advantage of our other service support options.
