Consistent circulation starts at the impeller. The Swimables 1HP Impeller Replacement (073128 / SW-21-003) is a precision-engineered replacement designed specifically for Pentair WhisperFlo® pool pumps operating at 1 horsepower. When an impeller becomes worn, cracked, or partially blocked, the pump may experience reduced flow, loss of efficiency, and increased motor stress.

This impeller restores proper hydraulic performance inside the pump, allowing water to move efficiently through the filtration and circulation system. Manufactured to OEM-equivalent specifications, it provides a reliable, cost-effective alternative to factory-branded impellers while maintaining proper fit and performance.

The Swimables 1HP impeller is commonly replaced during pump rebuilds, seal replacements, or when troubleshooting low flow or pressure issues.

Restores Proper Flow and Circulation Efficiency

The impeller converts motor rotation into water movement. Even minor wear can significantly reduce circulation and affect filtration, heating, and cleaner performance.

The Swimables 1HP impeller restores proper flow and pressure, helping the pump operate efficiently and maintain stable circulation throughout the pool system.

Designed for Pentair WhisperFlo® Pumps

This impeller is engineered specifically for compatibility with Pentair WhisperFlo® pumps configured with a 1HP motor. Accurate thread engagement and balanced construction ensure smooth installation and reliable operation.

Using the correct impeller helps prevent cavitation, vibration, and premature wear on seals and bearings.

Durable Construction for Long-Term Reliability

Pool pump impellers operate continuously under load in chemically treated water. The Swimables impeller is constructed from durable materials designed to resist erosion, cracking, 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 can compromise the entire circulation system.

Replacing the impeller helps:

• Restore proper water flow and pressure

• Prevent motor overheating and excessive wear

• Improve filtration, heater, and cleaner performance

• Extend the overall life of the pump

Routine impeller replacement is an important part of pump maintenance.
