Non-evaporable getter (NEG) pumps have an entire vary of functional and ergonomic advantages for functions that require cost-effective and reliable ultra-high vacuum conditions. 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 have no moving parts and are due to this fact maintenance-free.
Increased pumping efficiency
With these attributes, they’re predestined for a whole range of functions in research, drugs, business and analytics. In these areas, they reach pressures of much less than1x10-10 mbar as a end result of their operating principle. A critical requirement in such applications is the absence of mud particles as those badly influence the performance of the customers’ functions. Sintered NEG materials is extensively believed to strongly reduce emission of such particles into the appliance. Therefore, Gamma Vacuum developed its new NEG pumps which would possibly be based on sintered materials. “The elevated pumping performance of this NEG collection with respect to our typical NP sequence (NEG pumps primarily based on pressed material) and their superior hydrogen capability in comparability to the other NEG pumps out there on the market are further benefits”, says Dr. Stefan Lausberg, product manager for Gamma Vacuum.
Wide pumping speed range
The NEG series ranges from 50 l/s up to 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 five pumps have a 3-pin feedthrough which is a common style in the marketplace. In order to fulfil customers’ requests, the 410MS is equipped with a particular 4-pin feedthrough while it has the same pumping velocity as the 400NS.
Superior hydrogen pumping speed
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 especially 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 does not consume any electrical energy till it is saturated. “This makes it an power environment friendly, vibration-free and noiseless pump”, highlights product supervisor Dr. Stefan Lausberg. เกจวัดแรงดันแก๊สหุงต้ม : A NEG pump may be installed and operated in any orientation, even in confined spaces, and provides a practical method to maintain ultra-high vacuum pressures over a long period of time.
