FREQUENCY CHANGER

PRESSURE BOOSTERS WITH VARIABLE SPEED, SILENT OPERATION, CONSTANT PRESSURE, PIPELINES IN AISI 304, QUALITY FREQUENCY CONVERTER

These are automatic pressure booster sets for installation on the water mains with three phase electric power supply, transducer control and variable speed.

The speed of the first pump that starts is modulated by the inverter linked to an electronic board via a pressure transducer, so that outlet pressure is kept constant on the unit regardless of the quantity of water collected (within the flow rate limits of the first pump). When the quantity of water collected exceeds the flow rate of the first pump, the second pump is started up at a fixed speed, while the speed of the first continues to be modulated by the inverter. When the set water quantity has been delivered, the inverter controlled pump runs at a higher speed for a settable interval, to enable the storage of a certain amount of water underpressure, thereby prolonging the pump stand by time.
