Product overview
Diffuser, Replacement for Speck 433 Pool Pump — an aftermarket diffuser dimensioned to drop into Speck circulation pumps without modification. In service it converts the velocity leaving the impeller into pressure and directs flow into the discharge. It is a wear item: the sealing lip and locating tabs wear, letting water recirculate inside the pump instead of moving downstream. Ours is molded in reinforced thermoplastic and dimensionally checked against an OEM sample before tooling is signed off.
Send us the number stamped on your failed component and we will confirm the match against our fitment records before you order. Supplied factory-direct with a 50 pcs minimum, mixed cartons welcome, and OEM or private-label packaging available on request.
