Vacuum Pump Spares for Aerospace & Defence
Vacuum pump spares for aerospace and defence applications — TVAC chambers, vacuum heat treatment, helium leak detection, composite vacuum bagging, and EB welding. NADCAP-aware supply, AS9100 traceability, MOD/ITAR-compliant where required, with next-day UK delivery.
Vacuum pumps are used in aerospace and defence for thermal vacuum (TVAC) testing of satellites and avionics, vacuum heat treatment and brazing of high-performance alloys, vacuum infusion of carbon-fibre composites, helium leak testing of fuel systems, and altitude/space-environment simulation chambers.
Where vacuum is used in Aerospace & Defence
We supply spare parts to support every vacuum-based process in this sector — from frontline production equipment to laboratory and quality-assurance instrumentation.
Thermal vacuum (TVAC) chambers
Simulating space conditions to 1×10⁻⁶ mbar or lower for satellite, payload, and avionics qualification.
Vacuum heat treatment & brazing
Titanium, Inconel, and nickel-superalloy turbine and structural components for Rolls-Royce, BAE, and Airbus supply chains.
Composite vacuum bagging
Autoclave and out-of-autoclave (OOA) processing of CFRP wings, fuselage skins, radomes, and UAV airframes.
Helium mass-spectrometer leak testing
Fuel tanks, hydraulic lines, pressure vessels, and missile bodies tested down to 1×10⁻⁹ mbar·l/s.
Altitude / hypobaric chambers
Aircrew physiology training and ejection-seat qualification testing.
Electron-beam (EB) welding chambers
Engine components, fuel system parts, and ordnance casings.
Vacuum coating (PVD/sputtering)
Optical coatings, stealth coatings, and sensor windows for canopies, radomes, and seekers.
Freeze-drying of military rations & field pharmaceuticals
MRE / ORP (Operational Ration Pack) production and lyophilised emergency medical supplies.
Which pump types are used and why
Different applications in aerospace & defence drive different pump-technology choices. We support the full breadth of pump types installed in this sector.
Brand Affinities
- •Edwards GV / GXS dry screw (UK-built, MOD-familiar)
- •Edwards nXDS scroll for clean lab and inspection
- •Edwards STP turbomolecular for TVAC and EB
- •Leybold TURBOVAC and SCREWLINE for furnaces
- •Pfeiffer HiPace turbo and OmniStar RGA on TVAC
- •Agilent and INFICON helium leak detectors
Dry screw and multi-stage roots pumps
Clean, oil-free roughing for TVAC and EB welders — no hydrocarbon contamination of optics or coatings.
Turbomolecular pumps
Edwards STP, Pfeiffer HiPace, and Leybold TURBOVAC for high vacuum down to 10⁻⁸ mbar on TVAC and EB.
Cryopumps
Very large clean chambers where pumping speeds need to be in the tens of thousands of l/s.
Rotary vane (single and two-stage)
Autoclaves and composite layup — robust and cost-effective at moderate vacuum levels.
Helium leak detector packages
Dedicated turbo + diaphragm packages (Pfeiffer ASM, Agilent VS, INFICON) for 10⁻⁹ mbar·l/s leak detection.
The cost of vacuum downtime in aerospace & defence
TVAC campaign slots are booked months in advance; a pump fault can delay a satellite launch window by weeks and trigger contractual penalties. Heat-treat furnaces running NADCAP-controlled cycles cannot complete a part if vacuum integrity drifts — full re-run plus re-certification. UK primes typically demand same-day or next-day spares under MOD-flowdown service-level requirements.
Tip seal degradation on dry scrolls (silicone outgassing, composite resin volatiles)
Tip seal kits — Edwards nXDS, Agilent IDP
Turbo bearing failure from particulate ingress on chamber vents
Bearing service kits and lubricant cartridges (Edwards STP, Pfeiffer HiPace, Leybold TURBOVAC)
Rotary vane oil coking after long autoclave cure cycles at elevated temperature
Vane sets, exhaust mist filter elements, and high-temperature pump oil
Cooling water solenoids and inverter board failure on large dry pumps
Solenoid valves and replacement controller boards
