Pentair pumps

[hockeyrick]

Is there any hydraulic difference between Pentair Superflo and Whisperflo pumps???
Or any specific differences for that matter?

There are a number of small technical differences, but the only really significant difference is that SuperFlo models use impellers with lower ratings than the equivalently sized WhiserFlo. That means that the SuperFlo will move less water and draw less electricity compared to the "same size" WhisperFlo. It isn't a hydraulic difference, but the SuperFlo models also tend to come with standard motors, while the WhisperFlo models tend to come with high efficiency motors. However, lower flow rates are inherently more efficient, and that allows the SuperFlo to match or sometimes exceed the overall efficiency of a "same size" WhisperFlo, even though they would be less efficient if their sizes actually matched.
