Revised: 6/11/2025 Ii7II1iT Using a Pump Curve A pump curve helps you determine the best pump for your system.Pump curves show the relationship between flow and pressure(total dynamic head or"TDH"),providing a graphical representation of a pump's optimal performance range.Pumps perform best at their nominal flow rate.These graphs show optimal pump operation ranges with a solid line and flow rates outside of these ranges with a dashed line.For the most accurate pump specification, use Orenco's PumpSelectTM software.
