Sta-Rite C105-238PLA Impeller
This is the C105-238PLA impeller, sized for Sta-Rite Dyna-Glas/Dyna-Max Series in-ground pool and spa pumps. Impellers wear from cavitation, sand and grit in the water, and simple age, and a worn one is one of the most common reasons a Sta-Rite pump loses pressure or flow even though the motor still runs fine.
Replacing the impeller is usually a job that can be done without pulling the whole pump off its base: the motor is unbolted from the wet end, the old impeller is removed from the shaft, and the new one is threaded or keyed back on before the pump is reassembled. Check the shaft size and thread or key style on the old impeller against this part before ordering, since Sta-Rite uses several impeller styles across its pump lines even within the same horsepower class.

Frequently Asked Questions
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 Dyna-Glas/Dyna-Max Series in-ground pool and spa 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.
Q: What causes an impeller to wear out?
Sand and grit in the water, cavitation from running against a closed or restricted line, and simple age all wear the vanes down over time. Running the pump dry, even briefly, can chip or crack an impeller outright.
Q: Can a chipped impeller be repaired instead of replaced?
No. A chipped or cracked impeller is out of balance and should be replaced rather than repaired; running an unbalanced impeller accelerates wear on the shaft seal and motor bearings.
