Pentair 354816S Challenger High Pressure Pump Motor – 2 HP, 208-230 V, Single Phase

The Pentair 354816S Replacement Pump Motor is a heavy-duty, single-speed motor designed for select Pentair and Sta-Rite pool pump applications. It delivers 2 horsepower of dependable power and operates on a 208–230-volt, single-phase electrical supply. This motor features a 56Y square-flange frame and a Totally Enclosed Fan Cooled enclosure, commonly abbreviated as TEFC. Unlike an open drip-proof motor, the TEFC design prevents outside air from passing directly through the motor’s internal components. This helps reduce exposure to moisture, dust, debris, salt air, and other corrosive conditions commonly found around pool-equipment areas. Part 354816S is supplied as a replacement motor only. It does not include the complete pump, wet end, impeller, diffuser, seal plate, mechanical shaft seal, or other hydraulic components. Because pump motors with the same listed horsepower can have different service factors, frame styles, shaft configurations, and electrical requirements, compatibility must be confirmed before ordering.
