SEE REPLACEMENT PART: OBSOLETE

An impeller is one of the most important working parts inside a spa pump because it is what actually helps move the water, and this Balboa ITT impeller is designed for compatible Gemini and Gemini Plus pump applications where the original impeller has worn down or become damaged. When pump performance starts to feel weaker, rougher, or less consistent, the impeller is often one of the first parts worth replacing.

The one-size-fits-all compatibility across Gemini and Gemini Plus applications makes this a practical repair part for owners and technicians who need a more focused solution without replacing the full pump. That can be especially helpful when the motor and wet end still have life left, but the water-moving core of the pump is no longer performing the way it should.

Because the impeller directly influences flow and pump feel, using the correct replacement matters. A worn impeller can make the entire system seem tired, even when other components remain serviceable. Restoring the right impeller often brings back a stronger sense of pump confidence much faster than broader replacement work.

Installed in the proper Gemini or Gemini Plus setup, this impeller helps restore a cleaner water-moving path and supports a more dependable, more efficient pump rebuild overall.
