How to Build a Centrifugal Pump Curve Part 3: Motor Selection

In Part 2 of our How to Build a Centrifugal Pump Curve series, we added five head/capacity curves to the e-1510 4BD pump curve we are building. These curves reflect the tested performance of pumps with various-size impellers. Now, it's time to focus on the pump’s power requirement and how it....
