3.1.3.3 PUMP CURVES. With the system head curve defined, it is possible to select a pump to deliver the required capacity. Manufacturer’s published pump head-capacity curves for the selected type of pump will be used for this purpose. Since these pump curves usually apply to a particular impeller and pump design, different manufacturers

The system head curve can then be plotted on the pump performance curve for both single and dual pump operations to determine the operating points of the system. The change in the static head during drawing down will change the pumping rate. As shown in Figure 2, the normal pumping range will vary by the change in the static head. Table 2 ...

Understanding Centrifugal Pump Curves When selecting a centrifugal pump, one should match the performance of the pump to that needed by the system. To do that, an engineer would refer to a pumps composite curve. A typical composite curve includes the pump performance curves, horsepower curves and NPSH required.
