The Pentair WhisperFlo is primarily known as a single-speed or two-speed pool pump, not a variable speed pump. However, Pentair offers a separate line called the WhisperFlo VST, which is a variable speed version of the WhisperFlo pump. If you are specifically looking for a variable speed pump, make sure to choose the WhisperFlo VST model.
