Vacuum Pump Refurbishment
Full mechanical rebuilds of industrial vacuum pumps at our Sutton Coldfield workshop. Suitable for older pumps where a routine service won't restore performance, or for stock-build of refurbished exchange units. Documented warranty on every refurbishment.
Vacuum pump refurbishment is a full mechanical rebuild that takes a worn or end-of-life pump back to manufacturer-spec performance — typically including new bearings, shaft sleeves, vanes, all sealing, exhaust valves, gas-ballast valve, paint and detail, with a documented post-rebuild performance test.
2–6 weeks depending on pump size, scope, and parts availability.
- •Documented test certificate per pump
- •Warranty on every refurbishment
- •OEM-spec or OEM-equivalent parts to documented spec
What you get with refurbishment
Strip and inspect
Full dismantle and clean. Cylinder, rotor, and crank components measured against service limits — any out-of-spec castings replaced or remachined where possible.
Bearings, sleeves, and seals
All bearings, shaft sleeves, lip seals, mechanical seals, and shaft couplings replaced as standard.
All wear parts renewed
Vanes (or piston rings on rotary piston pumps), gaskets, O-rings, exhaust valves, gas-ballast valve, anti-suckback valve, and all filters.
Cylinder reconditioning
Worn or scored cylinders re-honed or re-bored where the casting allows. Replaced where wear exceeds service limit.
Paint and detail
External paintwork stripped and refinished in original or customer-specified colour. Nameplates re-fitted, branding preserved.
Performance test and warranty
Tested to manufacturer ultimate vacuum and pumping speed. Documented test certificate and warranty supplied with each refurbished pump.

When you'd typically need refurbishment
Common scenarios where customers ask for this service. If your situation isn't listed but sounds related, get in touch — we can advise.
- Pump is 15+ years old and a routine service hasn't restored performance
- Pump has been damaged by a process upset (water slug, particulate, oil starvation)
- Cost of a new replacement is prohibitive for a heritage installation (Stokes Microvac, Kinney KT, Welch DuoSeal, older Edwards GV)
- Building stock of refurbished exchange units for a service-exchange programme
- Original manufacturer no longer offers a factory rebuild
