1. Determine GPM and Ft./Hd. requirements from Specification Chart below.
2. Refer to manufacturer's pump curve of equipment you use.
3. Compare Part # and Model #. Do not rely on horsepower. Most manufacturers make both full-rated and up-rated pumps. This also relates to low
and high service factors.
4. Most pump curves will show Total Head in Feet on the left side vertically. Gallons per Minute are indicated horizontally across the page.
5. Draw an x where the two lines intersect. This will give you the pump required.
