Vacuum pumps for aerospace
Satellites, spacecraft and aircraft parts are tested and manufactured under vacuum: in thermal vacuum chambers, altitude simulations and wind tunnels, in coating, welding and leak testing. Edwards names backing pumps from atmospheric pressure to 10⁻² mbar for TVAC testing, Atlas Copco pumps for testing and manufacturing. Below you can see which series the manufacturers themselves name for these tasks – 98 models from 2 manufacturers.

In short
Aerospace: vacuum pumps – the key facts
- Atm to 10⁻² mbarFor TVAC testing in the space sector, Edwards names backing pumps from atmospheric pressure to 10⁻² mbar – mXDS, nXDS, XDS, EDS, GXS and nXRi – and the standards NASA GSFC-STD-7000 and NASA-STD-7012A.
- Space conditionsAccording to Edwards, space simulation means below 10⁻¹⁰ mbar at −80 to +180 °C; EH, GMB and EXS are named as parts of systems.
- Testing and manufacturingAtlas Copco names vacuum for the testing and manufacturing of spacecraft, satellites and aircraft, and GHS VSD+ and DWS VSD+ for it.
- Oxide-free weldsIn vacuum welding, according to Atlas Copco, little O2 and N2 remain in the chamber so that the weld does not oxidise – in low to high vacuum.
Applications
Aerospace: what vacuum pumps are used for
For each application: what the vacuum does and which series the manufacturers name for it. The information comes from the manufacturers’ own pages.
Thermal vacuum testing (TVAC) and space simulation
Components are tested under space vacuum and extreme temperatures. Edwards names backing pumps from atmospheric pressure to 10⁻² mbar for this (mXDS, nXDS, XDS, EDS, GXS, nXRi), systems with EH, GMB and EXS for space-like conditions below 10⁻¹⁰ mbar at −80 to +180 °C, as well as bake-out, outgassing and TML. Atlas Copco names the testing of components under space-like vacuum with DWS VSD+ and ZRS.
- Atlas CopcoDWS VSD+ Atlas Copco also names ZRS
- EdwardsmXDS, nXDS, XDS, EDS, GXS, nXRi Edwards names EH, GMB and EXS for systems

Altitude simulation, engine testing and wind tunnels
In the testing of liquid rocket engines, according to Atlas Copco, vacuum simulates altitude and provides thrust and combustion data; for altitude simulation Atlas Copco names DRB and GHS 1202–2002, for low-density wind tunnels ZRS. Edwards names the propulsion testing of ion thrusters and lists low-density wind tunnels for EH and GMB.
- Atlas CopcoGHS VSD+ Atlas Copco also names DRB and ZRS
- EdwardsmXDS, nXDS, nXRi, XDS, GXS, EDS, EXS, EH, GMB names EH and GMB; not in the series list on this page

Vacuum coating (PVD, CVD)
According to Atlas Copco, high vacuum ensures uniform, adherent layers. For thin-film coating Atlas Copco names DWS and ZRS, for hard coating (CVD/DLC), plasma coating, surface activation and roll and strip coating DWS VSD+, for coating systems GVD and GLS.
- Atlas CopcoDWS VSD+ Atlas Copco also names DWS, ZRS, GVD and GLS
Leak testing and leak detection
According to Atlas Copco, a defined vacuum makes even the smallest leaks detectable – in low to high vacuum. For leak test, leak detection and tightness testing systems, Atlas Copco names DRB, GLS and GVD.
Electron beam and vacuum welding
In vacuum welding, little O2 and N2 remain in the chamber so that the weld does not oxidise; Atlas Copco names low to high vacuum for this, without assigning a series.
- Atlas Copconames the application without a series

Selection
Aerospace: choosing a vacuum pump
What the manufacturers highlight for use in this industry.
Pressure range
For backing pumps in TVAC chambers, Edwards names atmospheric pressure to 10⁻² mbar; space simulation below 10⁻¹⁰ mbar is reached by systems with high vacuum stages. Atlas Copco names high vacuum for coating, and low to high vacuum for leak testing and welding.
Temperature and outgassing
Edwards names vacuum together with extreme temperatures of −80 to +180 °C as well as bake-out, outgassing and TML measurement in propulsion testing.
Standards
For TVAC testing in space qualification, Edwards names the standards NASA GSFC-STD-7000 and NASA-STD-7012A.
Designs in the range
The series named cover several designs: Atlas Copco names the speed-controlled screw vacuum pumps GHS VSD+ (oil-lubricated) and DWS VSD+ (dry); Edwards names scroll vacuum pumps with mXDS, nXDS and XDS, screw vacuum pumps with EDS and GXS, and Roots pumps with nXRi.
Frequently asked questions
Aerospace: frequently asked questions about vacuum pumps
Which vacuum pump for thermal vacuum tests (TVAC)?
For TVAC testing in the space sector, Edwards names backing pumps from atmospheric pressure to 10⁻² mbar: mXDS, nXDS, XDS, EDS, GXS and nXRi. The test combines vacuum with extreme temperature; as standards, Edwards names NASA GSFC-STD-7000 and NASA-STD-7012A.
How much vacuum does space simulation need?
For space-like conditions, Edwards names below 10⁻¹⁰ mbar, reached with systems of EH, GMB and EXS; the backing pumps work from atmospheric pressure to 10⁻² mbar. For space simulation, Atlas Copco names DWS VSD+ and ZRS.
What temperatures prevail in thermal vacuum chambers?
Edwards names −80 to +180 °C in combination with vacuum below 10⁻¹⁰ mbar.
Which vacuum pump for altitude simulation and engine test stands?
For altitude simulation, Atlas Copco names DRB and GHS 1202–2002 from the GHS VSD+ series; in the testing of liquid rocket engines, the vacuum simulates altitude and provides thrust and combustion data. Edwards names the propulsion testing of ion thrusters with bake-out and TML measurement as a system solution.
Which pump for low-density wind tunnels?
Atlas Copco names the ZRS Roots pumps for this, Edwards lists EH and GMB.
Which vacuum pump for PVD and CVD coating in aviation?
Atlas Copco names high vacuum for uniform, adherent layers and, as series, DWS VSD+ (hard coating CVD/DLC, plasma coating, surface activation, roll and strip coating), DWS and ZRS for thin-film coating, and GVD and GLS for coating systems.
Why is welding done in a vacuum?
