Gamma Vacuum introduces new sintered NEG pump series for analysis, medicine, industry and analytics

Non-evaporable getter (NEG) pumps have an entire vary of practical 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 results in low energy consumption, little noise, and no vibration. NEG pumps have no shifting parts and are therefore maintenance-free.
Increased pumping efficiency
With these attributes, they are predestined for a whole vary of purposes in analysis, medication, trade and analytics. In these areas, they reach pressures of less than1x10-10 mbar as a end result of their working precept. A critical requirement in such functions is the absence of mud particles as these badly affect the efficiency of the customers’ purposes. Sintered NEG materials is extensively believed to strongly scale back emission of such particles into the appliance. Therefore, Gamma Vacuum developed its new NEG pumps which may be based on sintered material. “ ตัววัดแรงดันน้ำ increased pumping efficiency of this NEG sequence with respect to our typical NP collection (NEG pumps based mostly on pressed material) and their superior hydrogen capacity compared to the opposite NEG pumps available on the market are additional benefits”, says Dr. Stefan Lausberg, product supervisor for Gamma Vacuum.
Wide pumping speed vary
The NEG collection ranges from 50 l/s up to 400 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 common type in the marketplace. In order to fulfil customers’ requests, the 410MS is equipped with a special 4-pin feedthrough whereas it has the same pumping velocity as the 400NS.
Superior hydrogen pumping pace
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 speed they are particularly well-suited within the ultra-high vacuum vary where hydrogen is the dominant fuel species.
Energy efficient, non-vibrating and noiseless
After the NEG pump has been heated up it doesn’t eat any electricity until it’s saturated. “This makes it an power efficient, vibration-free and noiseless pump”, highlights product manager Dr. Stefan Lausberg. Another benefit: A NEG pump can be installed and operated in any orientation, even in confined spaces, and offers a sensible approach to maintain ultra-high vacuum pressures over a long time period.
