High Vacuum (HV) and Ultra-high Vacuum (UHV) pumps for space simulation installations

Once primary vacuum levels have been achieved, high-vacuum (HV) to UHV (ultra-high vacuum) levels can be achieved using a variety of technologies depending on the gas molecules and particles you’re aiming to dispel.
Typical pressure ranges from 10^-2 mbar down to < 10^-11 mbar.


nEXT mechanical turbomolecular pumps Turbomolecular technology achieves high to ultra-high vacuum levels by deploying the principles of momentum drag. The multistage axial-flow turbine contains rapidly spinning blades which direct molecules toward the exhaust. The nEXT range includes ‘any orientation’ as well as ‘Split Flow’ variants. A wide range of models to choose from starting with the nEXT55 (55 l/s) up to the nEXT1230H (1250 l/s). nEXT M Magnetically Levitated Turbomolecular Pumps The rotor blades in magnetically levitated turbo pumps are held in position by precisely deployed electromagnets, eliminating the need for oil-lubricated mechanical bearing systems. They are lighter, more compact, can be mounted in any orientation and deliver contaminant-free vacuum levels. Pumps in this range include the nEXT2807M and the nEXT3207M delivering pumping speeds of 2,350 l/s and 3,200 l/s respectively. NEG pumps Non-evaporable getter (NEG) pumps use metals such as titanium, vanadium, and zirconium to absorb gas molecules. This is done by heating the getter material which in turn increases its ability to trap gases. Models in this range start from the 50NS/NP NEG Pump (50 l/s) and go up to the 410 NS/NP (400 l/s). TiTan ion pumps Also referred to as a ‘sputter ion pump’, this technology operates by ionizing has molecules using a strong electrical field to accelerate ion towards a solid electrode. Our ion pumps have also been used onboard spacecrafts within analytical instruments and for spectrometry applications. An extensive range of models are available in sizes ranging from the Mini TiTan Ion Pump with pumping speeds of 0.2 l/s, all the way up to the 1200LX TiTan Ion Pump with speeds of 1200 l/s. HyTan NEG-Ion pumps HyTan NEG-Ion Pumps comprise of both NEG and ion modules, efficiently combing 2 vacuum disciplines listed above into a single pump. Both modules are exchangeable and various sizes are available. Clean, quiet and versatile HyTan NEG-Ion Pumps also benefit from being and can be mounted close to your chamber unlike alternative large ion pumps. HyTan pumps start with the 100HS (100 l/s) and go up to the 500HP (500 l/s). TSP Pump A Titanium Sublimation Pump (TSP) works by heating a titanium filament to cause sublimation, forming a reactive titanium film on the chamber walls. The film reacts with residual gas molecules, forming stable compounds which remove gas molecules to maintain ultra-high vacuum conditions. Periodic reheating of the filament ensures continuous effectiveness. Pumping speeds starts with 1600 l/s (with an ambient shroud) and goes up to 12000 l/s (with cryogenic shroud). Cryogenic The cryogenic portfolio consists of cold heads, compressors, and cryopumps tailored for space and scientific environments. In propulsion testing, multiple cold heads are often used alongside turbopumps to capture heavy gases like Xenon, Krypton, and Argon. For thermal vacuum (TVAC) chambers, cryopumps are ideal for achieving high vacuum and are especially effective at removing water vapor from large test chambers. Our systems are built for precision, performance, and reliability in the most demanding applications. Contact us to learn more about our cryogenic solutions for space.
