7.2.1. Pump Performance without Cavitation

As long as the static pressure remains sufficiently high everywhere in the system, cavitation will not occur. In this case, for a given pump RPM, the pressure rise and flow rate are directly coupled, and can be plotted in a pump performance diagram, as shown below.
