Hayward SPX3215C Impeller with Screw – 1.5 HP (Full Rated)

Part # SPX3215C — a genuine Hayward replacement impeller designed for TriStar® pump models with a 1.5 horsepower rating (full rated) and in some cases 2.0 THP. This kit includes the impeller and the mounting screw for complete replacement.

Key Features

• OEM Hayward impeller specifically designed for TriStar pump models requiring this part number.
• Fits 1.5 HP full rated pump motors (and compatible 2.0 THP uprate versions) in the TriStar family.
• Includes mounting screw for secure installation and proper alignment of the impeller.
• Precision-machined to restore optimal flow, efficiency and motor load characteristics.
• Durable construction engineered for long service life in pool environments.

Typical Applications

This replacement impeller is used when the existing unit in a compatible Hayward TriStar pump is worn, damaged or underperforming—causing reduced flow, elevated motor current, or cavitation noise. Ideal when performing service or restoring original pump performance in a residential pool system.

Installation & Compatibility Notes

Before servicing, shut off the pump power at the breaker and relieve system pressure. Remove the pump housing and diffuser to access the impeller. Remove the old impeller and inspect the shaft and motor sleeve for wear. Install the Hayward SPX3215C impeller onto the motor shaft, secure with the included screw, and re-assemble the diffuser and housing. Confirm proper clearance to the volute and that the pump is primed and free of air pockets before running.

Why Choose This Impeller?

Using the genuine Hayward SPX3215C ensures the correct geometry, balance and performance as originally designed for the TriStar pump, maintaining flow, efficiency and reliability. It avoids potential issues caused by mismatched or generic impellers and supports proper fit, function and service life.

Maintenance Tips

• Inspect the impeller clearance and wear plate gap periodically; a larger gap can reduce efficiency and increase motor load.
• Check for debris behind the impeller that might cause imbalance, noise or vibration.
• When replacing the impeller, consider replacing or checking the mechanical shaft seal for signs of wear or leakage.
• Ensure pump is properly primed and not operating under air conditions which can lead to impeller damage or cavitation.
