Non-evaporable getter (NEG) pumps have a complete vary of practical and ergonomic advantages for applications that require cost-effective and reliable ultra-high vacuum circumstances. Unlike most vacuum pumps, NEG pumps are gas-capturing pumps that bind gases via sorption. This ends in low vitality consumption, little noise, and no vibration. NEG pumps don’t have any shifting parts and are due to this fact maintenance-free.
Increased pumping performance
With these attributes, they’re predestined for a complete vary of applications in research, drugs, trade and analytics. In these areas, they reach pressures of much less than1x10-10 mbar due to their working principle. A critical requirement in such purposes is the absence of mud particles as those badly affect the efficiency of the customers’ applications. Sintered NEG materials is widely believed to strongly reduce emission of such particles into the application. Therefore, Gamma Vacuum developed its new NEG pumps which are based mostly on sintered materials. “The elevated pumping efficiency of this NEG sequence with respect to our standard NP sequence (NEG pumps based mostly on pressed material) and their superior hydrogen capacity in comparison to the other NEG pumps obtainable available on the market are extra benefits”, says Dr. Stefan Lausberg, product supervisor for Gamma Vacuum.
Wide pumping speed range
The NEG collection ranges from 50 l/s as much as four hundred 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 typical type on the market. In order to fulfil customers’ requests, the 410MS is equipped with a particular 4-pin feedthrough while it has the same pumping speed because the 400NS.
Superior hydrogen pumping speed
NEG vacuum pumps can be used 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 particularly well-suited within the ultra-high vacuum vary where hydrogen is the dominant gasoline species.
Energy efficient, non-vibrating and noiseless
After the NEG pump has been heated up it doesn’t devour any electricity till it’s saturated. “This makes it an power efficient, vibration-free and noiseless pump”, highlights product supervisor Dr. ไดอะแฟรม ซีล . Another advantage: A NEG pump could be installed and operated in any orientation, even in confined spaces, and offers a sensible approach to keep ultra-high vacuum pressures over an extended period of time.
