The Hayward Diffuser (SPX3200B3) is the OEM replacement diffuser for Hayward TriStar VS, TriStar VS-C, TriStar XE, and TriStar VS 815/820 variable-speed pumps. The diffuser channels water flow from the impeller into the pump's volute, maintaining hydraulic efficiency and proper pressure output across the pump's speed range. Replacing a worn or cracked diffuser restores the pump to its designed flow characteristics.

This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering. Poolaroo Pro Tip When servicing the pump's wet end, inspect the impeller and diffuser together — wear or debris damage to one often affects the other. Confirm the position reference (v2 #7 or v2 #9) against your pump's exploded diagram to ensure you are replacing the correct diffuser assembly for your specific TriStar model.
