Non-evaporable getter (NEG) pumps have an entire range of useful and ergonomic benefits for functions that require cost-effective and dependable ultra-high vacuum conditions. Unlike most vacuum pumps, NEG pumps are gas-capturing pumps that bind gases via sorption. This leads to low power consumption, little noise, and no vibration. NEG pumps have no shifting components and are therefore maintenance-free.
Increased pumping performance
With these attributes, they are predestined for an entire vary of applications in research, medicine, trade and analytics. In เกจวัดแรงดันแก๊สco2 , they reach pressures of less than1x10-10 mbar because of their operating principle. A crucial requirement in such applications is the absence of dust particles as these badly affect the efficiency of the customers’ purposes. Sintered NEG materials is broadly believed to strongly reduce emission of such particles into the appliance. Therefore, Gamma Vacuum developed its new NEG pumps that are primarily based on sintered materials. “The increased pumping performance of this NEG series with respect to our standard NP sequence (NEG pumps primarily based on pressed material) and their superior hydrogen capability compared to the opposite NEG pumps out there 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 as a lot 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 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 pace 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 surface science. Due to their superior hydrogen pumping pace 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 doesn’t consume any electricity till it’s saturated. “This makes it an energy efficient, vibration-free and noiseless pump”, highlights product manager Dr. Stefan Lausberg. Another advantage: A NEG pump can be installed and operated in any orientation, even in confined spaces, and offers a sensible method to keep ultra-high vacuum pressures over a long time period.
