Description
This Challenger high-pressure pump power end is built for the CH-N1-3/4F, 1A 0.75 HP single-speed configuration running on 115/208-230 volts, giving you a precise wet-end match for existing Challenger plumbing and hydraulics. The Challenger high-pressure design delivers more head than standard circulation pumps, making it a strong choice for spa jets, in-floor systems, and elevated water features that demand higher pressure. Swapping the power end instead of the complete pump lets you keep a good motor in service while restoring the original flow and pressure of the system. Molded thermoplastic construction and a closed-impeller layout support efficient, continuous-duty pool and spa use.
Pro Tip
Pair this 355671 power end with a fresh shaft seal kit and a Challenger impeller sized for 0.75 HP to avoid leaks and ensure the pump reaches its designed performance.
