Oberdorfer 24 Seal Kit – Buna-n Replacement Part
The Oberdorfer 24 is a factory service kit that gathers the wear parts of a single pump model into one part number, so a rebuild can be done in one sitting rather than chased part by part. Buying the kit rather than individual components also keeps the elastomer grades matched across the pump, which is what keeps a rebuilt pump sealing the way the factory intended.
The usual symptoms that send someone looking for this kit are a drop in delivered flow, a pump that will no longer pull a prime, drips from the seal area, or a change in the noise the pump makes under load. All of those point at the wear items rather than the housing, and all of them get worse rather than better if the pump is left in service.
If the pump has been in raw water service, expect some cleanup of the bore and the shaft while it is open. Scale and light pitting under a seal face will chew through a new seal quickly, so dress those surfaces before the kit goes in.

Frequently Asked Questions
Q: Do I need any parts beyond the kit to finish the job?
Usually not, but gaskets or fasteners that are damaged on removal are worth having on hand. Check them as the pump comes apart.
Q: How often should a pump be rebuilt?
Duty decides it. A pump on continuous raw water service wears faster than one that runs occasionally, so go by observed flow and seal condition rather than a fixed calendar.
Q: Can I reuse the old parts that still look serviceable?
Elastomers take a set once they have been compressed and rarely seal as well the second time. If a component is in the kit, fit the new one.
Q: Should the pump be tested before it goes back in service?
Yes. Run it on a bucket or an open circuit first and confirm it primes, holds flow and stays dry at the shaft before it goes back into the system.
