Product Overview

The Hayward SPX3000B is a genuine OEM replacement diffuser designed for Hayward Super II® pool pumps rated at 2.5 HP and 3.0 HP. The diffuser directs water from the impeller into the volute, maximizing hydraulic efficiency and maintaining proper pump performance. A worn or cracked diffuser can reduce flow, lower filter pressure, create excessive noise, and decrease overall pump efficiency.

Important: This diffuser is intended for Super II pumps manufactured in 1989 and earlier. If your pump was manufactured in 1990 or later, verify compatibility before ordering, as a different diffuser may be required.
