Description of Pump Frofiles
a) Proportional pressure
• This mode is suitable for heating systems with radiators, to reduce noise caused by
heating fluid flowing through thermostatic valves.
• Head (pressure) decreases with decreasing flow rate (increasing system pressure
drop).
• Pump operating point: lies on the selected proportional pressure curve depending on
the current system pressure drop.
CONTROL MODE
DESCRIPTION
Proportional
pressure
I
The lowest curve of proportional pressure
II
The middle curve of proportional pressure
III
The highest curve of proportional pressure
AUTO
ADAPT
Automatically controls performance in the range from
the highest to the lowest proportional pressure curve
b) Constant pressure
• This mode is suitable for underfloor heating or for piping of a bigger size. It is also
suitable for all applications without variable characteristics (e.g. pumps for heating up
a HW storage tank) or for a circuit with a heat exchanger.
• Head (pressure) remains the same in the whole range of flow rates (does not change
with the system pressure drop).
• Pump operating point: moves on the selected constant pressure curve depending on
the current system pressure drop.
CONTROL MODE
DESCRIPTION
Constant
pressure
I
The lowest curve of constant pressure
II
The middle curve of constant pressure
III
The highest curve of constant pressure
AUTO
ADAPT
Automatically controls performance in the range from
the highest to the lowest constant pressure curve
c) Constant speed
• This mode is suitable for the maximum utilization of the pump performance or for use
in systems with constant resistance which require a constant pumping performance.
• Head (pressure) increases with decreasing flow rate (increasing system pressure
drop).
• Pump operating point: moves up or down on the selected curve depending on the
current system pressure drop.
