The Pentair Diffuser Assembly is a replacement pump component for compatible pool or spa pump assemblies. Pump parts must be matched carefully because small changes in series, horsepower, seal plate style, volute design, basket dimensions, diffuser geometry, or mounting points can affect performance and installation. This item is useful when rebuilding a pump that still has serviceable major components but needs a specific internal or external part replaced. Replacing the correct component can help restore flow, reduce leaks, improve priming, or bring the pump back into reliable operation. Confirm the pump model and part number C101-126B before ordering.
