SEE REPLACEMENT PART: OBSOLETE

The impeller is where motor energy becomes real water movement, so getting the correct replacement matters more than many spa owners realize. This 4.0 horsepower impeller is designed for Ultima and Ultra Flo applications using a 48 frame setup, making it a precise service part rather than a generic internal component.

Color coding helps technicians confirm they are working with the right specification, which is especially useful when multiple similar impellers may appear almost identical at a glance. Accuracy here helps preserve pump balance and expected output.

When an impeller wears down, circulation strength and jet feel can both suffer even if the motor is still operating. Replacing the impeller can often restore the missing performance without replacing the entire wet end or pump assembly.

For the intended 48 frame application, this part helps bring water movement back to the level the system was designed to produce.
