⚡ Waterway Viper 56-Frame Jet Pump – 5.0 HP Wet End – Dual Speed
Versatile two-speed performance for swim spas and large hot tubs
💧 Product Overview
The Waterway Viper 2-Speed 56-Frame Pump is engineered for high-flow, low-pressure applications in swim spas and large hot tubs. This versatile dual-speed pump features a two-speed motor with thermal protection, paired with a 5.0 HP-rated wet-end impeller designed for high water volume and exceptional flow performance.
The two-speed motor provides approximately 0.53 HP at low speed (1,450 RPM) for quiet filtration and circulation, switching to approximately 2.01 HP at high speed (2,850 RPM) for powerful jet performance and swim currents. Low speed draws just 1.8A for efficient continuous operation, whilst high speed draws 9-12.5A for maximum power output at 3.67 kW.
Operating at 230V/50Hz, the Viper uses a split-capacitor design (16 µF + 30 µF) for reliable two-speed operation. The robust 56-frame motor provides superior cooling and longevity, whilst the oversized 8-inch wet end handles high-volume water flow with ease. The wet end rotates in 90° increments for maximum plumbing flexibility. Built-in thermal protection safeguards the motor from overheating. Uses 2.5-inch Waterway unions (sold separately). Electrical cable not supplied – reuse existing wiring.

⚠️ IMPORTANT ELECTRICAL SAFETY:
All electrical work must be carried out by a qualified electrician in accordance with UK wiring regulations (BS 7671). Hot tubs require RCD protection (30mA). Ensure proper earthing and bonding of all electrical components. Two-speed pumps require appropriate wiring for both speed windings – consult a qualified electrician. The electrical cable is not supplied – your existing wiring from the previous pump must be reused and inspected before connection.
