About This Item
The Pentair 355122Z is the OEM replacement 1 HP impeller for the Dynamo aboveground swimming pool pump. If your Dynamo pump has lost prime, is running loud, or is delivering noticeably reduced flow, a worn or damaged impeller is one of the first components to inspect.
What It Does
The impeller is the rotating component inside the pump volute that draws water through the strainer housing and drives it through your filtration system. A cracked, worn, or clogged impeller directly reduces hydraulic output — restoring the OEM impeller returns the pump to its rated flow performance. Match the part number on your existing impeller before ordering; the Dynamo pump family spans multiple horsepower ratings, each requiring its own impeller.

Pro Tip
The Dynamo pump is available in multiple horsepower configurations — each uses a different impeller. Before ordering, check the part number molded or stamped on your existing impeller, or confirm the horsepower rating on your pump's nameplate. The 355122Z is the 1 HP impeller only. While the pump is open for impeller service, it is also a good time to inspect the shaft seal and lid O-ring — replacing worn seals during the same service call prevents a return trip for a water leak shortly after reassembly.
