Non-evaporable getter (NEG) pumps have a whole 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 by the use of sorption. This leads to low vitality consumption, little noise, and no vibration. NEG pumps don’t have any transferring components and are subsequently maintenance-free.
Increased pumping efficiency
With these attributes, they are predestined for a whole range of applications in analysis, medicine, trade and analytics. In these areas, they reach pressures of less than1x10-10 mbar because of their working precept. A important requirement in such purposes is the absence of mud particles as these badly affect the efficiency of the customers’ functions. Sintered NEG materials is broadly believed to strongly scale back emission of such particles into the application. Therefore, Gamma Vacuum developed its new NEG pumps which would possibly be based mostly on sintered materials. “The increased pumping efficiency of this NEG sequence with respect to our conventional NP series (NEG pumps based on pressed material) and their superior hydrogen capacity in comparison to the opposite NEG pumps out there on the market are extra benefits”, says Dr. Stefan Lausberg, product manager for Gamma Vacuum.
Wide pumping pace range
The NEG collection ranges from 50 l/s up to four hundred l/s in pumping speed: 50NS, 100NS, 200NS, 300NS, 400NS, 410NS. All pumps are mounted on a DN forty CF (2.75” CF) flange. The first 5 pumps have a 3-pin feedthrough which is a typical type in the marketplace. In order to fulfil customers’ requests, the 410MS is provided with a particular 4-pin feedthrough whereas it has the same pumping velocity as the 400NS.
Superior hydrogen pumping velocity
NEG vacuum pumps can be used in a broad spectrum of scientific and medical applications, like electron microscopes, analysis and medical accelerators or surface science. Due to their superior hydrogen pumping pace they are especially well-suited in the ultra-high vacuum vary the place hydrogen is the dominant gasoline 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 vitality efficient, vibration-free and noiseless pump”, highlights product supervisor Dr. Stefan Lausberg. Another advantage: A NEG pump may be installed and operated in any orientation, even in confined areas, and provides a practical method to preserve ultra-high vacuum pressures over a long time period.
