Waterway 3HP 3421221-1A Executive Pump 2 Speed

The Waterway Executive Pump 3421221-1A offers 3 HP two-speed performance supported by a robust 48-frame motor designed for demanding spa and hot tub applications. Built to match original Waterway engineering standards, the unit operates on 230 V and includes thermal overload protection for safe, consistent runtime. Its 6½ inch wet end produces strong head pressure and rotates in 90-degree increments to align cleanly with varying plumbing configurations. The 2 inch intake and discharge ports use male buttress threads to maintain efficient flow and compatibility with common spa fittings. With corrosion-resistant materials including Viton seals, 316 stainless steel components, and silicone carbide sealing surfaces, the pump provides reliable operation in harsh water conditions.
