Non-evaporable getter (NEG) pumps have a complete range of useful and ergonomic benefits for functions that require cost-effective and reliable ultra-high vacuum situations. Unlike most vacuum pumps, NEG pumps are gas-capturing pumps that bind gases by means of sorption. This ends in low power consumption, little noise, and no vibration. NEG pumps have no transferring elements and are due to this fact maintenance-free.
Increased pumping performance
With these attributes, they’re predestined for an entire range of purposes in research, medication, trade and analytics. In these areas, they attain pressures of much less than1x10-10 mbar because of their operating principle. A important requirement in such functions is the absence of dust particles as these badly affect the efficiency of the customers’ purposes. Sintered NEG materials is extensively believed to strongly cut back emission of such particles into the applying. Therefore, Gamma Vacuum developed its new NEG pumps that are based on sintered materials. “The increased pumping efficiency of this NEG collection with respect to our typical NP collection (NEG pumps based mostly on pressed material) and their superior hydrogen capacity in comparison to the opposite NEG pumps available available on the market are extra benefits”, says Dr. เพรสเชอร์เกจ4นิ้ว , 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 5 pumps have a 3-pin feedthrough which is a standard fashion available on the market. In order to fulfil customers’ requests, the 410MS is provided with a special 4-pin feedthrough while it has the same pumping speed as the 400NS.
Superior hydrogen pumping velocity
NEG vacuum pumps can be used in a broad spectrum of scientific and medical purposes, like electron microscopes, analysis and medical accelerators or surface science. Due to their superior hydrogen pumping speed they’re especially well-suited within the ultra-high vacuum range where hydrogen is the dominant fuel species.
Energy efficient, non-vibrating and noiseless
After the NEG pump has been heated up it does not devour any electrical energy till it is saturated. “This makes it an power efficient, vibration-free and noiseless pump”, highlights product manager Dr. Stefan Lausberg. Another advantage: A NEG pump can be put in and operated in any orientation, even in confined areas, and supplies a practical method to maintain ultra-high vacuum pressures over a long time period.
