The impeller is the core component responsible for water movement inside a pool pump. The Swimables 1.5HP Impeller Replacement (073129 / SW-21-004) is a precision-engineered replacement designed specifically for Pentair WhisperFlo® pool pumps operating at 1.5 horsepower. When an impeller becomes worn, cracked, or partially clogged, pump performance drops—resulting in low flow, reduced filtration efficiency, and increased motor strain.

This replacement impeller restores proper hydraulic performance, allowing the pump to circulate water efficiently through the filtration system. Manufactured to OEM-equivalent specifications, it provides reliable performance and proper fit without the premium cost of factory-branded parts.

The Swimables 1.5HP impeller is commonly replaced during pump rebuilds, mechanical seal replacements, or when troubleshooting circulation issues.

Restores Proper Flow and Pump Efficiency

Impeller wear directly affects water circulation and pressure. Even minor damage can significantly reduce system performance and place unnecessary load on the motor.

The Swimables 1.5HP impeller restores correct flow and pressure, helping the pump operate efficiently and maintain consistent water circulation throughout the pool system.

Designed for Pentair WhisperFlo® Pumps

This impeller is engineered specifically for compatibility with Pentair WhisperFlo® pumps configured with a 1.5HP motor. Accurate thread fit and balanced construction ensure smooth installation and proper alignment with internal pump components.

Using the correct impeller helps prevent cavitation, vibration, and premature seal or bearing failure.

Durable Construction for Long-Term Reliability

Pool pump impellers operate continuously under load and in chemically treated water. The Swimables impeller is constructed from durable materials designed to resist cracking, erosion, and deformation over time.

Its balanced design supports smooth rotation and reduces stress on the motor shaft and mechanical seal.

Why Replacing a Worn Impeller Matters

A failing impeller affects the entire circulation system.

Replacing the impeller helps:

• Restore proper water flow and pressure

• Prevent motor overheating and excessive wear

• Improve filtration, heating, and cleaner performance

• Extend the overall life of the pump

Routine impeller replacement is a key step in maintaining reliable pump operation.
