First-in-class hydraulic performances, modern design for the highest efficiency and quiet operations.
The correct pump should circulate all the water of a pool at least 4 times a day. Greater efficiency means lower running costs. The secret to greater efficiency is to minimize friction and turbulence. And less friction means also less noise. The Sta-Rite WhisperPro S5P5R Series features an innovative hydraulic design that moves water more efficiently and more quietly than competitive pumps. Its engineered thermoplastic housing withstands extreme heat and resists corrosion. Engineered to provide optimum performance in any size pool or pool and spa combination, WhisperPro is built to last a lifetime.
