Pentair Whisperflo Pool Pump 2 HP 115/230v

Product Information

We call it the WhisperFlo high performance pump for good reason. This innovative hydraulic design moves water more efficiently and more quietly than competitive pumps. Under typical operating conditions, the Pentair WhisperFlo offers the highest water flow of any high performance pump, yet with the lowest electricity consumption. And, the Pentair 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, the Pentair WhisperFlo is built to last a lifetime, and as a result, has become the industry’s top seller for years.

Compare the WhisperFlo to any other high performance pump, and you’ll hear the difference immediately. It’s quiet; and quiet means quality. Our proprietary hydraulic design, unique FunnelFlo diffuser, and high efficiency impeller work together to move water more efficiently than any other high performance pump. And the advantages don’t end there. The WhisperFlo’s oversized strainer basket extends time between cleanings, and the unique cam & ramp lid is transparent and easy to remove, making inspection and cleaning simple and quick. Built with heavy-duty components that are resistant to chemicals and corrosion, the WhisperFlo is a workhorse that will perform for years to come.

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