The most powerful, efficient WhisperFlo everThe new WhisperFloXF? pool pump was developed using the most advanced engineering tools available -- CFD (Computational Fluid Dynamics) and FEA (Finite Element Analysis). The proprietary impeller design delivers a higher level of precision concentricity for increased efficiency. The proprietary hydraulic isolator smooths the water flow inside the volute, raising the efficiency even higher. With capabilities in excess of 200 gpm, WhisperFloXF is an ideal choice for many residential and commercial applications; especially those involving water features, negative edges and slides.
