GVF

Pressure units with frequency variator

APPLICATIONS

Pressure equipments with electric switchboard and built-in variable-frequency-drive ABB or VACON, it adjusts the pump’s speed according to the flow demand, always keeping a constant pressure in the installation.
Suitable for the water supply at a constant pressure in blocks of flats, sports facilities, industries and hotels, without any power limitations of the pumps.
They can be mounted with just one pump or in 2 or 3-pumps equipments with alternation of a pump regulated by a drive (the rest of auxiliary pumps work in direct start).
The electric switchboard includes an auxiliary manoeuvre by pressostats in case of failure of the driver.
