System Curve

Static head + calculated friction resistance. The curve starts at Static Head and passes through Required Duty D1.

Static Head

Orifice

The orifice formula calculates friction loss only. After-orifice head = Pump Head − Orifice Friction Loss.

Orifice Size (mm)K-Factor

Selection can evaluate up to 6 duty points. Each point is entered as Flow + Head.

Pump Curve

Parallel curves use total system flow

Efficiency

Parallel curves use total system flow · efficiency remains per pump

Power

Total shaft power of all running pumps

NPSH

Parallel curves use total system flow · NPSHr remains per pump
