Pump shaft and sleeve repair

A worn bearing fit or seal area doesn’t mean a new shaft. We restore pump shafts and sleeves with HVOF carbide, hard chrome or weld overlay, then grind them back to print. Pump service centers send us shafts when a new one would take too long or cost too much.

What we repair

• Bearing journals and fits
• Seal and packing areas
• Shaft sleeves, wear rings and bushings
• Impeller hubs and keyed areas (with weld overlay as needed)

Choosing the coating

Wear problem	What we usually recommend
Abrasive slurry, erosion	HVOF tungsten carbide or chrome carbide
Smooth, hard seal or packing surface	Hard chrome
Corrosion in seawater or chemical service	HVOF Inconel (nickel alloy)
Heavy loss of material	Weld overlay or sulfamate nickel, then coat and grind

We’ll tell you which one fits from a photo of the wear, even when it’s the less expensive option.

Finish and quality

We grind to a mirror finish and to your print, which matters for runout on rotating shafts. Tell us your timeline when you request a quote. ISO 9001:2015.

Frequently asked questions

Should I repair the shaft or buy new?

If the core shaft is sound, a repair usually costs less and comes back faster than a new shaft.

Can you handle long pump shafts?

Send the length, diameter and weight and we will confirm.
