Sta-Rite C105-92PBSS Impeller
The Sta-Rite C105-92PBSS is a replacement impeller, built for Sta-Rite Dyna-Glas/Dyna-Max Series in-ground pool and spa pumps. The impeller is the spinning wheel inside the pump body that actually moves water: it bolts or threads onto the motor shaft and its curved vanes fling water outward into the diffuser or volute as it spins.
Impeller wear shows up as reduced flow, reduced pressure, or a pump that runs longer than it used to for the same amount of water delivered. Left too long, a badly worn or chipped impeller can also unbalance the motor shaft and shorten bearing and seal life elsewhere in the pump, so it is worth replacing at the first sign of falling performance rather than waiting for a full failure.

Frequently Asked Questions
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 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.
