We call it the WhisperFlo® pump for good reason.

This innovative hydraulic design moves water more efficiently and more quietly than competitive pumps. Under typical operating conditions, WhisperFlo offers the highest water flow of any high performance pump—yet with the lowest electrical consumption. And, WhisperFlo is designed to be a tireless workhorse. Its engineered thermoplastic housing withstands extreme heat and resists corrosion.

The commercial grade motor frame has a rustproof, stainless steel motor shaft and sealed bearings that never need lubrication. Engineered to provide optimum performance in any size pool or pool and spa combination, WhisperFlo is built to last a lifetime, and as a result, has become the industry’s top seller for years.

The WhisperFlo® pump delivers maximum circulation efficiency at the lowest operating cost and long, troublefree life with minimal maintenance. Our legendary hydraulic design has been refined over 40 years for superior performance. No wonder more than 2 million Pentair pumps have been selected by pool professionals.
