Non-evaporable getter (NEG) pumps have a complete range of practical and ergonomic advantages for applications that require cost-effective and dependable ultra-high vacuum situations. Unlike most vacuum pumps, NEG pumps are gas-capturing pumps that bind gases via sorption. This results in low vitality consumption, little noise, and no vibration. NEG pumps haven’t any shifting components and are therefore maintenance-free.
Increased pumping performance
With these attributes, they are predestined for a complete vary of purposes in analysis, drugs, business and analytics. In these areas, they attain pressures of less than1x10-10 mbar because of their operating principle. A important requirement in such applications is the absence of dust particles as those badly influence the efficiency of the customers’ functions. Sintered NEG materials is widely believed to strongly reduce emission of such particles into the applying. Therefore, Gamma Vacuum developed its new NEG pumps which are based mostly on sintered materials. “The elevated pumping efficiency of this NEG collection with respect to our conventional NP series (NEG pumps based mostly on pressed material) and their superior hydrogen capacity compared to the opposite NEG pumps available available on the market are extra benefits”, says Dr. Stefan Lausberg, product supervisor for Gamma Vacuum.
Wide pumping speed vary
The NEG sequence ranges from 50 l/s as much as four hundred l/s in pumping velocity: 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 typical type on the market. In order to fulfil customers’ requests, the 410MS is equipped with a special 4-pin feedthrough whereas it has the identical pumping velocity as the 400NS.
Superior hydrogen pumping speed
NEG vacuum pumps can be utilized in a broad spectrum of scientific and medical purposes, like electron microscopes, analysis and medical accelerators or floor science. Due to their superior hydrogen pumping pace they’re especially well-suited in the ultra-high vacuum range the place hydrogen is the dominant gas species.
Energy efficient, non-vibrating and noiseless
After the NEG pump has been heated up it doesn’t consume any electrical energy until it is saturated. “This makes it an vitality environment friendly, vibration-free and noiseless pump”, highlights product manager Dr. Stefan Lausberg. เกวัดแรงดันน้ำ : A NEG pump could be installed and operated in any orientation, even in confined areas, and supplies a sensible approach to maintain ultra-high vacuum pressures over an extended time period.
