Sta-Rite C1-200PA Diffuser
The Sta-Rite C1-200PA is a replacement diffuser, built for Sta-Rite Dyna-Glas/Dyna-Max Series in-ground pool and spa pumps. The diffuser 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.
Cracks and chips in a plastic diffuser usually come from age and thermal cycling, from a pump that has been run dry, or from sand and grit wearing away the wall thickness over years of service. Inspect the o-ring or gasket surface where it seals against the pump body at the same time, since that surface is easy to nick during disassembly.

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 diffuser sizes across their horsepower range, so match the part number exactly.
Q: What causes a diffuser 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 diffuser be glued or patched?
No. A cracked diffuser 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 diffuser 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.
