The Jabsco 1983-0020 is a genuine Jabsco replacement pump shaft made from Hastelloy, a nickel-based alloy chosen for liquids that attack ordinary stainless steel. It is the high-corrosion-resistance alternative to the stainless 1983-0010 shaft and is used where a Jabsco flexible impeller pump handles chemicals, brines or other aggressive fluids.
The shaft is the backbone of the pump, carrying the impeller and providing the sealing surface for the shaft seal. When it pits or grooves, seals leak and impellers loosen. Replacing it with the correct Hastelloy shaft keeps the pump compatible with the liquid it was specified for and protects the new seal and bearings.

Frequently Asked Questions
Q: Why would a pump need a Hastelloy shaft?
Hastelloy resists pitting and chemical attack far better than stainless steel, so it is specified when the pumped liquid would corrode a standard shaft.
Q: Can I swap my stainless shaft for this Hastelloy shaft?
Where both parts are listed for your pump, yes. It is an upgrade in corrosion resistance, but check that the seal and impeller are also compatible with the liquid.
Q: What causes a shaft to fail early?
Common causes are a leaking seal allowing fluid into the bearings, running the pump dry, misalignment, and pumping a liquid the shaft material was not chosen for.
Q: How do I confirm this shaft fits my pump?
Check the model number on the pump plate against the Jabsco parts list for that model, or send us a photo and we will confirm it.
Not sure this is the right part? Send us a Picture of the Pump Plate on your pump and the CLR Marine team will confirm the correct pump shaft.
