Match the horsepower rating, voltage, and frame size on your existing pump label. South Seas Spas use single-speed and two-speed jet pumps. Use the fitment form above to confirm the correct replacement.

My South Seas spa pump is humming but not moving water. What could be wrong?

A humming pump usually indicates a seized motor or a failed start capacitor. Check the impeller for debris first — a clogged impeller is a common cause. If clear, the motor or capacitor likely needs replacement.
