# Swimables 3/4HP Impeller for WhisperFlo Pumps

Proper water circulation depends on a correctly sized impeller. The **Swimables 3/4HP Impeller Replacement (073127 / SW-21-002)** is designed specifically for **Pentair WhisperFlo® pool pumps** operating at **3/4 horsepower**. When an impeller becomes worn, damaged, or partially clogged, pump efficiency drops—leading to poor circulation, reduced filtration, and increased strain on the motor.

This impeller restores the pump’s ability to move water efficiently through the system, helping maintain balanced flow, consistent pressure, and dependable performance. Manufactured to OEM-equivalent specifications, it delivers proper fit and performance without the higher cost of factory-branded components.

The Swimables 3/4HP impeller is commonly replaced during pump rebuilds, seal replacements, or when diagnosing low flow or pressure issues.

### Restores Proper Flow and Hydraulic Performance

The impeller is the core component responsible for converting motor power into water movement. Even slight wear can reduce circulation efficiency and compromise overall pool performance.

Replacing the impeller helps restore proper flow rates, ensuring filtration systems, heaters, and cleaners operate as designed.

### Designed for Pentair WhisperFlo® Pumps

This impeller is engineered specifically for Pentair WhisperFlo® pumps configured with a 3/4HP motor. Accurate threading and balanced construction allow for smooth installation and stable operation.

### Durable Construction for Long-Term Reliability

Pump impellers operate continuously under pressure in chemically treated water. The Swimables impeller is constructed from durable materials designed to resist erosion, cracking, and deformation.

Its balanced design supports smooth rotation, reducing stress on the motor shaft and mechanical seal while promoting long-term reliability.
