Pump Selection

Pump selection is based on required fluid flow rate and total head against which the pump must operate, including friction losses and net vertical lift. A selection is made from among alternatives to optimize hydraulic efficiency and meet other operating requirements. Figures 31-28 through 31-30 show three sets of performance curves for a selected pump, operating at speeds of 3,500, 1,700, and 1,170 rpm, respectively.

Table 31-1 provides data from a system curve showing the relation between head loss (HL) and fluid flow rate
