The Waterway 3421221-1A Executive Pump is a 3 HP, two-speed spa pump built on a rugged 48-frame motor with 230 V power and 2″ intake/discharge ports. Designed for premium spa and hot tub systems, it features a large 6½-inch diameter wet end for higher head pressure—and the wet end can be rotated in 90° increments to align with varying plumbing layouts. The motor is thermally protected and equipped with Viton seals and corrosion-resistant materials (316 stainless casing, silicone carbide seals, etc.) to stand up to harsh spa environments. Whether used for high-flow jets or standard circulation, this model delivers flexibility and durability in one package.

Highlights

• Large 2″ Intake & Discharge Ports: Designed with generous 2-inch male buttress thread connections (measuring approximately 3″ OD) for high flow and compatibility with existing spa plumbing.

• Rotatable Wet End Design: The wet end can be clocked every 90°, making installation and retrofits easier when space or plumbing alignment is limited.

• Advanced Seal & Casing Construction: Featuring Viton bellows, silicone-carbide shaft seals, and a 316 stainless steel casing, built for durability in chlorinated, brominated or salt environments.
