Important Notice: This Waterway component has been discontinued by the manufacturer. A compatible Aqua-Flo XP3 4.0hp impeller is available as a direct substitute and fits 2 1/2" x 2 1/2" wet end configurations.

This closed face impeller was designed specifically for Waterway Viper circulation systems featuring 2 1/2" inlet and outlet ports (approximately 3 9/16" thread measurement). The 4.0 horsepower component typically pairs with 12 amp motors in spa applications.

Engineered by Waterway Plastics for their Viper series pumps, this 4.0hp rated component requires installation onto a 4.0hp or higher thru bolt motor assembly. Compatible wet ends must accommodate the specified dimensions. Note: shaft seal requires separate purchase.
