11. SETTINGS AND PERFORMANCE OF PUMP
11.1 Relationship between pump settings and its performance
Setting
Pump Characteristics
Curve
Functions
AUTO (factory
settings)
Highest to Lowest
Proportional Pressure
Curve
“Autoadaptation” function will automatically control the pump
performance within the specified range.
·Adjust the performance of the pump according to the size of the
system;
· Adjust the performance of the pump according to the load change
over a period of time;
In the “Autoadaptation” mode, the pump is set to proportional
pressure control mode.
BL (1-3)
Proportional Pressure
Curve
The pump working point will move up and down on the proportional
pressure curve according to the flow needs of the system, when
the flow demand reduces, the pump pressure supply will drop while
when the flow demand increases, it will rise.
HD (1-3)
Constant Pressure
Curve
The pump working point will move back and forth on the constant
pressure curve according to the flow needs of the system. The
pressure supply of the pump remains constant, having nothing to do
with the flow demand.
HS (1-3) Constant speed curve
Run on the constant curve at a constant speed. In speed HS (1-
3) mode, the pump is set to run on the maximum curve under all
working conditions. Set the pump to HS3 mode in a short time, then
gas in the pump will be vented quickly.
