Sta-Rite C101-122E Volute
The Sta-Rite C101-122E is a replacement volute, built for Sta-Rite Dyna-Glas/Dyna-Max Series in-ground pool and spa pumps. The volute sits around or just past the impeller and directs the water it flings outward into an organized flow toward the discharge port, converting the impeller's spin into usable pressure.
A worn or cracked volute lets water recirculate internally instead of moving out through the discharge, which shows up as a pump that runs but delivers noticeably less pressure than it used to. Replacing it along with the impeller during a rebuild is common practice, since both parts see the same wear conditions.

Frequently Asked Questions
Q: Will this fit a different horsepower pump in the same series?
Not necessarily. Sta-Rite Dyna-Glas/Dyna-Max Series in-ground pool and spa pumps use different volute sizes across their horsepower range, so match the part number exactly.
Q: What causes a volute to crack?
Age, thermal cycling, running the pump dry, and years of sand or grit passing through the water all contribute. A sudden crack after a hard freeze is also common on pumps left full of water in cold weather.
Q: Can a cracked volute be glued or patched?
No. A cracked volute should be replaced rather than repaired, since a patch will not hold up to the pressure and vibration inside a running pump.
Q: How do I know if my volute needs replacing?
Reduced pressure or flow with the motor and impeller both in good condition is the main sign, along with visible cracks, chips, or wear where it seats against the pump body.
