13.4.7.2. CONSTANT SPEED MODE VS CAPACITY
The speed of the pump depends on the capacity of the unit. This speed range is determined during
commissioning to adjust the power of the pump to the load drops of the installation.
13.4.7.3. CONSTANT OUTPUT PRESSURE MODE
The frequency inverter controls the pump’s speed to maintain an even water pressure at the output of the
unit, regardless of the number of operating terminals.
Installation of one or more three-way valves on the facility to maintain the minimum
required pressure.
