Waterway Plastics 310-7440 Champion Impeller - 1 HP

What This Part Is Used For
The Waterway Plastics 310-7440 impeller is the hydraulic drive component used inside Champion series pool and spa pumps equipped with a 1 horsepower motor. It is responsible for pulling water into the pump housing and pushing it through the circulation system. This impeller is matched specifically to the Champion wet end geometry to maintain proper flow characteristics. It is typically replaced during pump rebuilds, seal failures, or when circulation performance drops.

Why This Part Matters
Pump performance is directly tied to the condition and accuracy of the impeller. A worn or incorrect impeller can cause low flow, noisy operation, or increased load on the motor. Over time, this can lead to overheating, seal damage, or premature motor failure. Installing the correct OEM impeller restores designed flow rates and protects the pump assembly as a whole.
