Pump Power Consumed Curve
Select this button to enter part load unloading curve information for variable volume pumps.
This cubic curve represents the pump’s electric consumption at varying water flow rate. Enter the cycle point to tell the program at which flow rate the pump will begin to cycle on/off rather than unload along the curve. The equation for the Pump Power Consumed Curve is:
Where:
y = pumps’s electric consumption (%)
C1 to C4 = coefficients
x = % full waterflow
The curve has the following fields:
X Axis: Full Waterflow (%)
Y Axis: Full power (%)
Curve Type: Cubic.
Waterflow Min / Max: Minimum and Maximum Waterflow percentage
