What This Part Is Used For The Hayward SPX3000BN is a diffuser used inside compatible Hayward pump wet ends. It surrounds the impeller and guides water into the pump housing for consistent internal flow. This part is installed behind the pump seal plate area during wet end service. Why This Part Matters A cracked or warped diffuser reduces pump efficiency and can change system pressure. Poor internal flow can contribute to noisy operation and weak circulation. Replacing the diffuser restores proper hydraulic channeling inside the wet end.
