Couldn't load pickup availability
Pentair’s Challenger high pressure line is designed for applications that need higher discharge pressure than standard circulation pumps, including raised spas, water features, and long or restrictive plumbing runs. The CH-N1-1F, 1-1/2A configuration corresponds to a 1 HP, standard duty model on 115/208-230V service, so matching that designation is important when ordering this power end. Warranty on replacement parts like 355672 generally covers manufacturing defects only and assumes installation follows Pentair guidelines and local codes; always review the current Pentair warranty statement and your invoice for exact terms.
Q: Will this power end fit any Challenger high pressure pump? A: No. It is intended for Pentair Challenger high pressure models labeled CH-N1-1F, 1-1/2A at 1 HP and 115/208-230V; always verify the data on your pump’s nameplate before ordering. Q: How heavy is the CH-N1-1F power end assembly? A: Distributor listings show this style Challenger power end shipping at roughly 32 pounds, so plan handling and mounting accordingly.

Challenger High Pressure Pump Power End CH-N1-1F 115/208-230 355672
OEM Pentair Challenger high-pressure power end CH-N1-1F, 1-1/2A, 115/208-230V, part 355672, for 1 HP standard duty pump rebuilds.
Features
Direct-fit power end for 1 HP Challenger high-pressure CH-N1-1F, 1-1/2A models. Supports 115/208-230V standard duty single-speed installations. Factory-assembled sub-assembly simplifies repairs and helps restore full pressure.
Description
This Challenger high-pressure pump power end assembly is built for Pentair CH-N1-1F, 1-1/2A standard duty pumps running on 115/208-230 volt service, so it matches your original 1 HP configuration without reworking the pad or plumbing. It replaces the complete power section with a factory-matched unit, restoring the internal tolerances and sealing surfaces that are critical for reliable high-head performance on spas, elevated features, and long plumbing runs. By swapping the entire power end instead of mixing worn components, you reduce troubleshooting time, improve operating pressure, and cut down on noise and vibration from an aging pump.
Pro Tip
Plan to install a new mechanical seal and the correct Challenger high-pressure impeller 355369 during the power end swap so your rebuilt pump starts with fresh, matched internals and is less likely to develop leaks or weak pressure.

Installation Tips
Disconnect and lock out power at the breaker before working on the pump. Confirm the model tag on your existing unit lists CH-N1-1F and 1-1/2A with 1 HP and 115/208-230V before installing this power end. Support the motor and housing during removal and reassembly to avoid stressing the plumbing. After installation, prime the pump, check for leaks, verify correct rotation, and monitor pressure and flow on startup.
