SC-FC-LC 3X5.50

Working Principle

• The frequency converter in the panel continuously adjusts the pump speed according to the current load conditions.

• A pressure sensor connected to the installation measures the system pressure and transmits it via a precise 4-20mA signal to maintain optimal pressure levels.

• In case of increased demand and insufficient pressure, additional pumps are activated automatically, starting with the most powerful pump available.

• During reduced demand, pumps are deactivated sequentially, beginning with the oldest, to maintain system pressure at the desired setpoint.
