Non-evaporable getter (NEG) pumps have an entire vary of functional and ergonomic benefits for functions that require cost-effective and dependable ultra-high vacuum situations. Unlike most vacuum pumps, NEG pumps are gas-capturing pumps that bind gases by the use of sorption. This leads to low vitality consumption, little noise, and no vibration. NEG pumps haven’t any transferring parts and are due to this fact maintenance-free.
Increased pumping performance
With these attributes, they are predestined for an entire vary of functions in research, drugs, business and analytics. In these areas, they attain pressures of much less than1x10-10 mbar due to their working principle. A critical requirement in such functions is the absence of dust particles as those badly affect the efficiency of the customers’ functions. Sintered NEG material is widely believed to strongly cut back emission of such particles into the appliance. Therefore, Gamma Vacuum developed its new NEG pumps that are primarily based on sintered materials. “The elevated pumping efficiency of this NEG sequence with respect to our conventional NP sequence (NEG pumps primarily based on pressed material) and their superior hydrogen capability compared to the opposite NEG pumps obtainable available on the market are further benefits”, says Dr. Stefan Lausberg, product supervisor for Gamma Vacuum.
Wide pumping velocity range
The NEG collection ranges from 50 l/s as much as 400 l/s in pumping speed: 50NS, 100NS, 200NS, 300NS, 400NS, 410NS. All pumps are mounted on a DN 40 CF (2.75” CF) flange. The first five pumps have a 3-pin feedthrough which is a common style on the market. In order to fulfil customers’ requests, the 410MS is supplied with a particular 4-pin feedthrough whereas it has the identical pumping pace as the 400NS.
Superior hydrogen pumping pace
NEG vacuum pumps can be used in a broad spectrum of scientific and medical functions, like electron microscopes, research and medical accelerators or floor science. Due to their superior hydrogen pumping velocity they are particularly well-suited within the ultra-high vacuum range the place hydrogen is the dominant gas species.
Energy environment friendly, non-vibrating and noiseless
After the NEG pump has been heated up it does not consume any electrical energy till it’s saturated. “This makes it an power efficient, vibration-free and noiseless pump”, highlights product manager Dr. Stefan Lausberg. Another advantage: A NEG pump could be put in and operated in any orientation, even in confined spaces, and supplies a practical way to keep ultra-high vacuum pressures over an extended time period.
