Waterway Viper 5HP Dual-Speed Spa Pump, 56-Frame — 2-1/2in. Intake & Discharge, 230V (3722021-1V)

The Waterway Viper 5HP dual-speed spa pump (model 3722021-1V) runs on 230V and is built around a robust 56-frame motor for enhanced strength and cooler operating temperatures. The Viper wet end is specifically engineered to match 56-frame motors, optimizing hydraulic performance. Plumbing features include a large 2-1/2in. intake and a 2-1/2in. discharge to improve flow and reduce noise. Efficiency is boosted by the two-speed motor’s four sets of insulated windings, while durability and quieter operation come from two double shielded ball bearings packed with moisture resistant grease, extending overall motor life.
