Repair Kits & Service Kits

It depends on the pump family, but a service kit typically holds the elastomer seals, O-rings, gaskets and filters replaced at every service; an overhaul kit adds bearings, vanes or tip seals and shaft seals. Each product page lists the actual contents for that kit.

When ultimate pressure no longer recovers after an oil and seal change, when the pump is noisy or draws more current than rated, or when the running hours have passed the manufacturer's overhaul interval. Bearing noise in particular should not be postponed — a failed bearing can take the rotors with it.

Seal and filter kits are routinely fitted in-house with the manual. Bearing replacement and rotor work need the correct pullers, torque values and clearance measurement — those are worth sending out, or ask us for the service. Either way, do not mix old and new seals in the same joint.

By serial number. Several popular models changed seal cross-sections or scroll geometry mid-production, and the wrong revision will either not seal or not fit at all. Send the model and serial number and we will confirm the revision before shipping.

Yes — we run dry pump repair and overhaul for the common Edwards, Leybold, Ebara, LOT and Shimadzu families, with a listed replaceable-parts checklist per pump family. Final scope is confirmed against the nameplate, serial number and teardown findings.
