Hayward SPX2800B Diffuser

What This Part Is Used For
The Hayward SPX2800B is a diffuser used inside compatible Hayward pump wet ends. It surrounds the impeller and guides water through the internal flow path. This part is installed behind the strainer housing area as part of the pump’s hydraulic assembly.

Why This Part Matters
A worn or cracked diffuser reduces efficiency and can change filter pressure readings. Poor internal flow can lead to weak returns and noisy operation. Replacing the diffuser restores proper channeling and supports consistent circulation.
