A diagram supplied by manufacturers of pumps and used to identify a pump for a particular duty (see Fig. 46). The rate of flow is presented on the x-axis and the delivered head or pressure on the y-axis. The performances of a number of pumps are typically presented spanning an acceptable range of efficiencies. Each area corresponds to a name or code, which is a combination of case number, impeller size, and speed.
