Pentair 355022S 1HP Square Flange Motor for WhisperFlo WF-4 & WF-26

The Pentair 355022S 1HP Square Flange Pool Pump Motor is a genuine OEM single-speed replacement motor engineered for Pentair WhisperFlo WF-4 and WF-26 in-ground pool pumps. Running at 115/208-230V with a 56Y square flange mount, this motor delivers consistent, reliable water circulation and is built to Pentair factory specifications for a direct drop-in replacement.

🚩 PRO TIP:   When replacing this motor, always install a new shaft seal. Reusing an old seal is the #1 cause of new motor failure. We recommend the Pentair 356198 Seal Kit for a perfect, salt-resistant seal. Also, verify your voltage (115V vs 230V) at the time clock before wiring!
