Non-evaporable getter (NEG) pumps have a complete range of functional and ergonomic advantages 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 via sorption. This leads to low vitality consumption, little noise, and no vibration. NEG pumps don’t have any shifting components and are due to this fact maintenance-free.
Increased pumping efficiency
With these attributes, they’re predestined for a whole range of purposes in research, medication, business and analytics. In these areas, they attain pressures of less than1x10-10 mbar as a result of their working precept. A important requirement in such applications is the absence of dust particles as those badly affect the performance of the customers’ purposes. Sintered NEG material is broadly believed to strongly scale back emission of such particles into the applying. Therefore, Gamma Vacuum developed its new NEG pumps which would possibly be based on sintered material. “The increased pumping efficiency of this NEG sequence with respect to our standard NP sequence (NEG pumps primarily based on pressed material) and their superior hydrogen capacity in comparison to the opposite NEG pumps available in the marketplace are further benefits”, says Dr. Stefan Lausberg, product manager for Gamma Vacuum.
Wide pumping speed vary
The NEG sequence ranges from 50 l/s up to 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 5 pumps have a 3-pin feedthrough which is a typical style available on the market. In order to fulfil customers’ requests, the 410MS is supplied with a particular 4-pin feedthrough while it has the same pumping speed as the 400NS.

NEG vacuum pumps can be utilized 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 in the ultra-high vacuum range where hydrogen is the dominant gas species.
Energy efficient, non-vibrating and noiseless
After the NEG pump has been heated up it doesn’t devour any electrical energy until it is saturated. “This makes it an power environment friendly, 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 sensible approach to keep ultra-high vacuum pressures over an extended period of time.
