General Pump Design

• Pump Curve A pump Performance Curve would consists of the following

characteristics:

Pump Head-Capacity Curve Efficiency Curve BHP (Power) Curve, and NPSHR Curve

Pump Head-Capacity curve could be generated using the Velocity triangle

analysis mentioned in Affinity Law:

Ideal head curve generated

using impeller geometry.

The losses are subtracted

from the ideal head curve to

arrive at actual head curve.
