When & Why to Replace
Replace the SPX3200B3 if your pump is showing reduced flow, poor priming, cavitation, excessive noise, or after impeller replacement. Installing a fresh diffuser ensures optimal water flow path, maintains proper impeller spacing, reduces turbulence, and helps restore full rated pump performance — especially important on higher-flow or variable-speed systems.
Installation Notes
To install, drain and safely disable the pump, then open the wet-end housing. Remove the old diffuser (if present), clean the seating surface, and position the SPX3200B3 into place using the 3-pin mounting alignment. Reinstall the impeller, shaft seal, and housing O-rings per manufacturer guidelines, then reassemble. Always ensure gaskets and O-rings are clean and seated properly for leak-free performance.
