Swimables 3/4HP Impeller for Pentair WhisperFlo Pumps | 073127 SW-21-002
Restore Your Pump’s Efficiency and Flow
If your pool pump is struggling to keep up with daily circulation, the problem may be your impeller. The Swimables 3/4HP Impeller Replacement (073127 SW-21-002) is designed to restore proper water flow, pressure, and performance to your Pentair WhisperFlo pump. This direct OEM-style replacement ensures your system runs at the correct horsepower, protecting both the motor and your pool’s overall circulation system.
The impeller is one of the most important components in any pool pump. It’s responsible for drawing water into the pump and pushing it through your filtration, heating, and sanitizing systems. When an impeller becomes worn, cracked, or clogged with debris, the pump loses efficiency, making it harder to maintain clean, clear water. Replacing it with a Swimables impeller is an affordable and effective way to extend the life of your pump and restore performance.
