HYDRIC PLANTS OF PRESSURE GVH AND GVA REALIZED WITH PUMPS TO VARIABLE SPEED FOR PLANTS WITH CONSTANT PRESSURE

The main purpose of the pressurization system in the working with “variable speed” is to keep the pressure constant in the hydric plant to the value of the nominal pressure P (set-point set up).

The attainment and the maintenance of the pressure and the constant value, to the change of the hydric request and then to the delivery, are due to the presence of the inverter of frequency that determines the working variable of the pumps under inverter of the pressurization system. Besides this disposal keep always optimal electric and mechanical conditions for the working of the pumps.

USES

They are conceived to feed water for automatic working in suitable quantity for uses:

• Civil and residential building, hotels, hospital, community, schools;
• Irrigation by shower and by flowing;
• Industrial application;
• Aqueduct use.
