Jabsco 12316-1002 Small Wearplate
The Jabsco 12316-1002 is a genuine replacement small wearplate for Jabsco 18690 series AC macerator pumps and 22130 series macerator units. The wearplate sits behind the impeller and takes the rubbing wear of the impeller vanes so the pump body itself is protected. Its flat face is one wall of the pumping chamber, so it has to stay smooth for the vanes to seal as they sweep past.
When the wearplate is grooved or scored, liquid slips back past the vanes on every revolution, output falls and the pump is slow to prime even with a new impeller. On a macerator pump, solids in the waste stream speed this wear up, so check the wearplate every time the impeller is changed. Replace it once a step or groove can be felt with a fingernail, and fit it the same way round as the original.

Frequently Asked Questions
Q: How do I know the wearplate is worn?
Run a fingernail across the face where the vanes run. If it catches on a step or groove, the plate should be replaced.
Q: Will a new impeller fix low output on its own?
Not if the wearplate or end cover is grooved. Liquid slips through the groove whatever the condition of the impeller.
Q: Does the wearplate have a correct orientation?
Yes. Fit it the same way round as the one removed so any locating features line up with the body.
Q: Should I replace the impeller at the same time?
Usually. A worn wearplate often comes with a worn impeller, and fitting both restores full output.
