Description
Revive the water-moving power of your Pentair pool pump with the Swimables Impeller SW-21-301, an exact-match replacement for the Pentair 355043. Sized for pumps running a 0.5 HP full-rated or 0.75 HP up-rated motor, this impeller fits Pentair Challenger, Pinnacle, SuperFlo, and SuperMax models. Precision-molded from resilient materials, it restores the flow rate and pressure output your pool circulation system was designed to deliver. Swapping in a fresh impeller when the original shows signs of wear is one of the most effective ways to reclaim lost pump performance, and the SW-21-301 makes the job approachable for service pros and weekend DIYers alike.
