Magnetically levitated turbomolecular pumps for coating, research and industry
Edwards Vacuum has developed a new series of magnetically levitated turbomolecular pumps that can withstand the demands of both challenging industrial environments and research processes.
The oil-free nEXT2807M and nEXT3207M Maglev pumps are specially designed for areas where a contamination-free vacuum is required for high process quality. The virtually maintenance-free models (up to 80,000 hours) are among the lightest and most space-saving turbopumps in their class.
The pumps are designed to achieve consistently good results even in the most adverse environments and harsh industrial processes. Their robustness makes them best suited for a wide range of applications for the use in the R&D and industrial markets; including various coating applications, vacuum ovens, thermal vacuum chambers for space applications, and high energy physics applications.
"In actual use, the nEXT M pumps offer their users a whole range of advantages," explains the Product Manager at Edwards Vacuum, Jinane Haddad. "Besides their low vibrations, which is crucial in many environments, the pumps also feature hydrocarbon-free performance, durability, and versatility, with efficient water cooling. This results in an overall extension of the operating and maintenance intervals and ultimately a higher pumping capacity of the nEXT M series.
"As the process reliability directly impacts overall productivity and profitability, maintaining a consistent level of performance is essential," adds Jinane Haddad. The design and functional features of the new Edwards series contribute to this in equal measure: with a bespoke rotor design, the nEXT M series have an excellent pumping speed - up to 3,200 l/s for the larger nEXT3207M. The smaller nEXT2807M version has a pumping speed of up to 2,500 l/s (nitrogen). A reduced weight of the rotors decreases power consumption, especially in the start-stop phases.
"nEXT M pumps are the ideal solution for industrial and R&D processes that require minimal vibrations and no hydrocarbons. The bottom line is that with this innovative turbomolecular pump technology, we ensure that sensitive processes in particular are not negatively affected by external interference," concludes Jinane Haddad.
