Every pump has a pump curve or performance curve--a graph of the overall performance capabilities of your pump. A pump curve may also be displayed in a chart format and can provide the same information.
Either way, a pump curve or performance chart displays a pump’s ability to sustain a certain flow rate (gpm) at a specific pressure (psi).
