How to Read a Pump Curve Intro to Pumps

These curves show that actual performance of the pump at various impeller diameters. For this pump the maximum impeller diameter is shown as 6 inches and minimum is 3 inches. Impellers are trimmed in a machine shop to match the impeller to the head and flow needed in the application....
However, by setting the system pump to operate at a fixed flow rate, you can obtain the data necessary to generate a system resistance curve. For the system shown below in Figure 1, a system resistance curve cannot be generated because the system has more than one loop:

Reading a Basic Pump Curve: The sloping curve you see in the middle shows you how much flow and head the pump will produce. But remember, a pump can only generate the flow and head plotted on this line when it's operating properly and if nothing's been done to alter its speed or the impeller diameter. On most pump curves, the Horizontal Axis you see will display flow (and be shown in Gallons need of educational research pdf Pump Curves Listed below are .pdf representations of the pump performance curves for all the Liberty Process Pumping solutions that Liberty Process Equipment currently represents.

  • The pump performance curve describes the relation between the flowrate and the head for the actual pump. Other important information for a proper pump selection is also included - like efficiency curves , NPSH r curve , pump curves for several impeller diameters and different speeds , …
  • System changes can play havoc with the pump operating point and the pump may end up running well away from the rated flow and the system may need to be throttled to keep the pump on its curve or to control the flow to suit the process.

  • Knowing how to read a multistage pump curve is essential to the health of your pumping system. Running too far out on the curve, or too far back can damage the pump, cause excessive energy consumption, and overall poor performance.
