Sta-Rite C101-182 Diffuser
The Sta-Rite C101-182 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.
Because the diffuser 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: 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.
