Sta-Rite J105-22PA Impeller
Sta-Rite lists the J105-22PA as the impeller in the PL-Series convertible jet pumps. A pump that runs but delivers little or no water, or that has started making a grinding or rattling noise, often needs this part rather than a new pump.
Because the impeller sits directly on the motor shaft, this is also the part most likely to need replacing after the pump has run dry or ingested debris that jammed or chipped the vanes. Inspect the mechanical seal and diffuser or volute for matching damage at the same time, since a failed impeller often takes the seal with it.

Frequently Asked Questions
Q: Is this impeller threaded or keyed onto the shaft?
Sta-Rite impellers in this class are typically threaded onto the motor shaft. Confirm the thread size against the original part, since it varies across pump lines even at the same horsepower.
Q: How do I know if my pump needs a new impeller?
Falling flow or pressure with the motor still running normally, a grinding or rattling noise, or visible chips and cracks in the old impeller are the usual signs. A pump that hums but moves no water at all can also mean a seized or badly damaged impeller.
Q: Do I need to replace the seal at the same time?
Not always, but inspect it while the pump is open. An impeller that failed from a dry-run event or debris often damaged the mechanical seal as well, and it is cheaper to replace both while the pump is already apart.
Q: Will this impeller fit a different horsepower pump in the same series?
No. Sta-Rite PL-Series convertible jet pumps use different impeller sizes for different horsepower ratings even within the same body style, so match the part number exactly rather than just the pump family.
