Challenger High Pressure Power End CH-N1-1FE 115/208-230 | 355674
Couldn't load pickup availability
The Challenger high pressure line is built to deliver higher head for raised spas, features, and longer plumbing runs than a standard circulation pump. The CH-N1-1FE, 1-1/2AE configuration combines a 1 HP full-rated / 1.5 HP up-rated energy efficient motor with high pressure hydraulics, so matching those model codes is critical when selecting a power end. Warranty coverage on this assembly typically follows Pentair’s replacement part policy and generally applies to manufacturing defects only, assuming proper installation and operation within published limits; always verify the current terms on your sales invoice and Pentair’s warranty documentation.
Q: What models does this 355674 power end fit? A: It is intended for Pentair Challenger high pressure pumps labeled CH-N1-1FE, 1-1/2AE with 1 HP full-rated / 1.5 HP up-rated, running on 115/208-230V. Q: Is this an energy efficient replacement? A: Yes. The CH-N1-1FE, 1-1/2AE designation indicates an energy efficient motor matched to the Challenger high pressure wet end for reduced power consumption at the same performance point.

Challenger High Pressure Power End CH-N1-1FE 115/208-230 355674
OEM Pentair Challenger high-pressure power end CH-N1-1FE, 1-1/2AE, 1 HP energy efficient, 115/208-230V, part 355674.
Features
- Direct-fit power end for 1 HP full-rated / 1.5 HP up-rated Challenger high-pressure EE models. Energy efficient design for 115/208-230V single-speed applications. Factory-assembled unit simplifies rebuilds and helps restore stable system pressure.
Description
This Challenger high-pressure pump power end assembly is configured for CH-N1-1FE, 1-1/2AE energy efficient models, giving you a matched 1 HP full-rated / 1.5 HP up-rated power section on 115/208-230 volt service. By replacing the complete power end, you refresh the motor, shaft interface, and key internal alignments that control how the pump builds pressure and handles demanding high head systems. The result is more consistent pressure at spa jets and water features, less vibration, and fewer callbacks compared to patching an older unit with scattered parts.
Pro Tip
During the power end swap, install a new mechanical seal and the correct Challenger high-pressure impeller for your horsepower rating so the new assembly is not paired with worn hydraulic components.

Installation Tips
Shut off and lock out power at the breaker before you touch the pump. Confirm your nameplate lists CH-N1-1FE and 1-1/2AE with the correct voltage before installing. Support the motor and wet end during removal and reassembly to avoid stressing rigid plumbing. After installation, prime the pump fully, check for leaks at all joints, verify correct rotation, and monitor pressure and flow on initial startup.
