WHISPERFLO Incorporates Innovative Hydraulic Engineering to move water more efficiently and quietly than competitive pumps. Under typical operating conditions, WHISPERFLO offers the greatest water flow of any high performance pump—yet with the lowest electrical consumption. To circulate more water in less time and at the lowest cost, choose quiet, reliable, WHISPERFLO.

WHISPERFLO is engineered to provide optimum performance in a complete range of installations, including pool/spa combinations. It operates suction-side, pressure-side, and in-floor cleaning systems, and is compatible with pressure or vacuum systems, sand filters, diatomaceous earth filters, and cartridge filters.

The Industry Standard by every Measure:
We call it WhisperFlo® 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 rust-proof, 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.
▪ WhisperFlo costs less to operate, because it uses less horsepower to produce required water flow.
▪ Whisper-quiet operation documented in rigorous ETL tests.
▪ Patented oversized strainer basket extends time between cleanings.
▪ See-through lid makes inspection fast and easy – engineered polymer remains clear and strong for years.
▪ User-friendly cam and ramp lid is easy to remove and re-secure properly every time.
