Sta-Rite C101-276P Diffuser
The Sta-Rite C101-276P 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.
A worn or cracked diffuser 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: 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.
Q: Should I replace the impeller at the same time?
Inspect it while the pump is open. The diffuser and impeller wear under the same conditions, so it is common to replace both during one rebuild rather than opening the pump twice.
Q: Does this come with a new o-ring or gasket?
This listing is for the diffuser itself. Check the sealing surface on the old part and order a matching o-ring or gasket separately if it is worn, cracked, or was damaged during disassembly.
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.
