Vacuum pump repair kits are comprehensive overhaul packages — going beyond a routine service kit — that include all wear parts plus longer-interval components like bearings, anti-suckback valves, and (where applicable) hinge bars and piston rings, for a full pump rebuild.
What's included in repair kits
- Major repair kits — all consumable wear parts plus bearings, anti-suckback valves, and longer-interval items for a full overhaul
- Complete rebuild kits — major repair kit + ironware (e.g. piston rings, hinge bars) for rotary piston pump major rebuilds
- Turbo bearing service kits — bearing and lubricant cartridge replacement for hybrid-bearing turbomolecular pumps
- Welch DuoSeal 1402K-06 — the iconic major repair kit for the long-running Welch DuoSeal 1402
- Stokes Microvac major overhaul kits — hinge bars, piston rings, exhaust valves, gaskets, seals, bearings
When should repair kits be replaced?
Major overhaul interval reached (8,000–16,000h or 5–10 years)
Routine major rebuild restores pump performance to as-new condition. Far cheaper than pump replacement.
Pump performance significantly degraded
Reduced ultimate vacuum that a minor service doesn't fix typically indicates broader wear — bearings, anti-suckback valves, possibly cylinder housing.
After a major process upset or contamination event
Solvent slug, water ingestion, or particulate event may damage bearings and seals beyond a routine service kit. Full rebuild restores reliability.
How to spot a problem
- Reduced ultimate vacuum that doesn't improve with a minor service
- Bearing noise, vibration, or higher running temperature
- Multiple service items needing simultaneous replacement
- Pump approaching documented major-overhaul hour interval
