Hayward SPX3000BN Diffuser – Replacement for Super II Pumps (0.75–1.5 HP)
Part # SPX3000BN — a replacement diffuser designed for use in Hayward Super II pump models (SP3000 / SP3000X series) manufactured after 1988. This diffuser helps ensure proper water flow through the pump housing and supports efficient circulation and filtration performance.
Key Features
- Compatible with Super II pumps rated from ¾ to 1½ HP.
- Precisely engineered to fit the original pump housing for a secure, leak-free installation.
- Ensures optimal hydraulic flow path — helps maintain strong suction, reduced cavitation risk, and stable pump performance.
- Durable molded construction for long-term pool use under chemical and water exposure.
Typical Applications
Use this diffuser when the original has cracked, become worn, chipped, or degraded — symptoms often noticed as reduced flow, air getting into the pump, poor suction or noisy pump operation. It’s appropriate for routine maintenance or pump rebuilding when restoring flow and reliability for SP3000/ SP3000X Super II pumps.
Installation & Compatibility Notes
Before servicing, shut off the pump power and drain water from the pump housing. Remove the old diffuser and inspect the housing and impeller for wear. Install the SPX3000BN diffuser carefully, ensuring it seats properly on the shaft/impeller hub. Reassemble the pump, seal all connections, prime the system, and check for proper flow and prime stability.
Why Choose This Diffuser?
Using the correct SPX3000BN diffuser restores proper flow dynamics inside the pump, helping ensure efficient circulation, reduce energy loss, and extend pump life — all critical for consistent pool water turnover and filtration.
Maintenance Tips
- Inspect the diffuser whenever you service the pump housing or notice reduced performance.
- Ensure the impeller and housing are free of debris before installing the new diffuser to avoid damage or imbalance.
- If replacing the diffuser, consider inspecting the shaft seal — impaired seals often accompany diffuser wear.
- After installation, monitor pump suction and return flow to confirm proper operation and absence of air leaks or cavitation.
