A centrifugal pump curve is the fastest way to stop guessing and start diagnosing. If you can read the curve, you can tell whether your pump is sized correctly, where it should run, how much power it will pull, and whether cavitation or seal failures are "baked in" by the operating point. This guide shows you how to interpret the four lines on a typical performance chart—then how to use them to make plant decisions that save energy and prevent failures.
