Full Product Description +

Impeller condition directly affects pump performance, flow rate, and overall system efficiency. The Swimables 3HP Impeller Replacement (073131 / SW-21-006) is a precision-engineered replacement designed for Pentair WhisperFlo® and IntelliFlo® pool pumps rated at 3 horsepower. When an impeller becomes cracked, worn, or clogged with debris, pumps can lose prime, deliver poor flow, or place excessive strain on the motor.

This impeller restores proper water movement through the pump housing, allowing the pump to generate the pressure and circulation needed for filtration, heating, and cleaner operation. Manufactured to exact fitment standards, it serves as a reliable alternative to OEM impellers at a competitive value.

The Swimables 3HP impeller is commonly replaced during pump rebuilds, seal replacements, or when diagnosing low-flow or overheating pump issues.


Restores Proper Flow and Pump Efficiency

The impeller is the heart of the pump’s hydraulic system. Damage or wear can drastically reduce circulation and lead to overheating or motor failure.

The Swimables 3HP impeller restores correct water flow and pressure, helping the pump operate efficiently and maintain consistent circulation throughout the pool system.


Designed for WhisperFlo® and IntelliFlo® Pumps

This impeller is engineered specifically for compatibility with Pentair WhisperFlo® and IntelliFlo® pumps that use a 3HP motor configuration. Proper sizing and thread fit ensure smooth installation and reliable performance.

Using the correct impeller helps prevent cavitation, vibration, and premature wear of pump components.


Durable Construction for Long-Term Use

Pump impellers operate under constant load and exposure to chemically treated water. The Swimables impeller is constructed from durable materials designed to resist cracking, warping, and erosion over time.

Its balanced design supports smooth rotation and reduced stress on the motor shaft and seals.


Why Replacing a Worn Impeller Matters

A failing impeller can impact the entire pool system.

Replacing the impeller helps:

  • Restore proper circulation and pressure

  • Prevent motor overheating and strain

  • Improve filtration and cleaner performance

  • Extend the life of the pump motor

Routine impeller replacement is a key part of pump maintenance.
