Whether you're upgrading from an aging single-speed pump that drives a noticeable summer power bill or building a new pool from scratch, this 1.5 HP variable speed pool pump runs anywhere from 1,150 to 3,600 RPM and gives three preset modes for backwash, daily filtration, and quiet overnight circulation. A permanent magnet motor runs cooler and quieter than the induction motors in older single-speed pumps, and a reinforced PP-GF30 plastic housing with Type 3 waterproof protection shrugs off splash, sun, and chemical exposure on the pool pad. A 115 GPM max flow rate, 50 ft. max head, and 0.22 in. (5.5 mm) max particle pass keep filtration cycles efficient on full residential pools, and self-priming with a 78.74 in. (2 m) lift means the pump pulls water up from below the deck on first start. The detachable filter basket captures leaves, hair, sand, and small twigs before they reach the impeller, making routine cleaning a quick lift-empty-rinse job. Dual 1.5 in. (50 mm) and 2 in. inlet and outlet connections install in 2-3 simple steps for both replacement and new builds. Worried about energy use over a long season? The variable speed control is built specifically to throttle back during low-demand hours, so you do not pay for full-RPM circulation around the clock.
