One common means of increasing the heads developed by a centrifugal pump is to underfile the outlet tips of the impeller blades, as shown in Figs. 28–1 and 28–2. However, as can be concluded from the performance charts presented in these figures, the effects of under filing vary in pumps of different geometries. Even in the same pump, the percentage of increase in head achieved by underfiling varies with flow rate.
