    Non-Evaporable Getter (NEG) Pumps

    Our NEG pumps feature a cutting-edge design, employing a non-evaporable, compact getter material with a porous structure. This design allows for the efficient adsorption of reactive gas molecules, such as nitrogen and oxygen, while enabling rapid diffusion of hydrogen. Specifically crafted for UHV applications, NEG pumps offer unparalleled H2 pumping speeds due to their compact size and significant material capacity, ranging from 50 to 3,500 l/s of hydrogen. DOWNLOAD THE BROCHURE



    • Extended Operation: Capable of running for prolonged periods without power, NEG pumps are perfect for "pump down, stay down" scenarios.
    • Reactivation Capability: As they become saturated, NEG pumps can be reactivated multiple times without venting to the atmosphere.
    • Compact and Efficient: Ideal for enhancing the performance of ion pumps or operating as standalone solutions, NEG pumps are the compact, efficient choice for UHV applications.

    Pressed NEG Discs vs. Sintered NEG Discs

    Edwards offers two types of Gamma Vacuum NEG pumps, the NP series based on pressed discs and the NS series based on sintered discs. What's the difference between the two?

    Pressed NEG discs, created through cold-pressing getter alloy powder, differ from sintered discs in their manufacturing process and resulting structure; the latter involves mixing getter powder with evaporator granules, pressing into tablets, and then sintering to create a porous structure with enhanced gas molecule accessibility. This fundamental difference gives sintered discs a lower density and higher porosity compared to pressed discs, affecting their sorption capacity and pumping speed, while also reducing particle emission into the vacuum chamber.



    HyTan NEG-Ion Pumps: The Ultimate UHV Solution

    The HyTan NEG-Ion Pump combines the best of NEG and ion pump technologies, offering unmatched efficiency in gas removal across the UHV spectrum. This innovative blend ensures high pumping speeds for not only H2 but also for chemically active gases like N2, O2, and CO, while effectively handling all gas species, including noble gases and methane.

    Optimized for superior performance in an innovative compact design, all pump components are packaged into the user’s vacuum chamber. This space-saving design reduces the pumps external footprint, making it the pump of choice for systems and applications with limited available space. DOWNLOAD BROCHURE



    • Space-Saving Design: With all components integrated into the vacuum chamber, the pump minimizes external footprint, ideal for space-constrained systems.
    • Modular Construction: Adapt to changing system requirements by easily swapping pump modules, ensuring flexibility and longevity.
    • Optimized Performance: Achieve low, stable base pressures with reduced pump-down times, enhancing system efficiency and reliability.
