The Waterway Plastics Pump 3721621-1V is an ideal choice for high performance and long life in spas. It features a Viper wet end designed specifically for 56-frame motors, providing increased strength and cooler operating temperature for longer motor life. Its Viton seals provide superior heat resistance and durability, while its two double shielded ball bearings with moisture resistant grease ensure quieter operation and longer life. The 2-1/2 inch intake and discharge provide higher flow rates for increased water pressure, temperature control, and circulation. Additionally, the dual speed motor has four sets of insulated windings to ensure maximum efficiency.

It is also California Title 20 Compliant, making it an ideal choice for any home. This pump meets all stringent energy efficiency requirements and helps conserve natural resources. Furthermore, the large 8" diameter wet end allows for increased volume capacity, while the split capacitor (start and run) reduces energy consumption. With its thermally protected motor, you can be sure that your pump will last. Not to mention, the highly versatile wet end can be rotated every 90 degrees for maximum convenience.
