Product Description

Challenger® high pressure pumps are designed specifically for applications requiring higher pressure operation to feed multiple needs beyond pool water circulation. These needs include spa jets, in-floor cleaning systems, as well as decorative water features like waterfalls and fountains. Plus, they provide effective power while remaining highly efficient and delivering years of unattended performance. Challenger pumps come equipped with rugged fiberglass reinforced housing that features closed impellers and durable, custom-molded thermoplastic components that stand up to high pressure operation year after year. Beyond efficiency, the top criteria for your pump should be long, trouble-free life and easy service. Challenger® high pressure pumps perform year after year because of superior design and the most rugged construction. Service-friendly features make routine maintenance a snap.
