Sta-Rite C101-284A Volute
This is the C101-284A volute for Sta-Rite Dyna-Glas/Dyna-Max Series in-ground pool and spa pumps. Because it channels every gallon the impeller moves, a cracked or worn volute shows up as reduced pressure, an external leak at the pump body, or a rattling noise even when the impeller itself is in good shape.
Because the volute bolts or seats directly against the pump body, fit and orientation matter as much as the part number. Match this part to the exact model being serviced and check that any sealing o-ring or gasket is also in good condition before reassembly.

Frequently Asked Questions
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.
Q: Should I replace the impeller at the same time?
Inspect it while the pump is open. The volute and impeller wear under the same conditions, so it is common to replace both during one rebuild rather than opening the pump twice.
