Warranty coverage, when available, typically requires proper sizing, installation to local codes, and use of OEM parts; always confirm details with your distributor before installation

Q: Do I need to change the shaft seal when installing this power end? A: Yes, Pentair and major distributors recommend replacing the shaft seal and related o-rings whenever the pump end is opened or replaced to prevent leaks and early failure.

OEM Pentair Challenger 355670 power end for CH-N1-1/2F 3/4A 115/208-230 pumps. Replace the wet end, keep your motor, and restore high-pressure performance.
Features

Description
This Challenger high-pressure pump power end is built for 0.5 HP class CH-N1-1/2F, 3/4A standard 115/208-230 configurations, where higher head is required. The OEM assembly maintains the correct hydraulic profile so your system can deliver the pressure needed for spa jets, in-floor cleaners, and raised features. Replacing the power end instead of the complete pump lets you keep a good motor while restoring output and efficiency for demanding residential and light commercial pool and spa applications.
Pro Tip
Always pair a new Challenger power end with a fresh shaft seal, gaskets, and a properly sized Challenger impeller to avoid leaks and recover full rated performance.
Installation Tips
Disconnect power at the breaker and verify zero voltage before service. Confirm your motor horsepower, frame, and voltage match the CH-N1-1/2F, 3/4A 115/208-230 configuration. Use new seals and o-rings during assembly, align plumbing carefully, and check for leaks and proper priming on startup.
