System Load Curve

Demand of your Hydraulic Setup

The system load curve is a representation of the required pump pressure to move fluid through a fixed hydraulic setup at various flow rates. It helps to match the right pump size for a given hydraulic setup. The intersection of pump supply (flow-pressure curve) and hydraulic setup demand (system load curve) is the maximum achievable duty point.

In this lesson, you will learn…

• … why the system load curve is of importance in pump selection
• …what the dynamic and static head of system load curve represent
• …how the system load curve can be calculated with Bernoulli’s equation of energy conservation
• …how the system load curve can be determined experimentally
• …how to select the right pump size with a given system load curve
