Municipal, industrial and agricultural pressure boosting, water treatment, washing systems, raising systems.
. Pressurisation system composed of 2 vertical electric pumps Diva, connected to an inverter panel which guarantees a constant water pressure when the flow rate changes, with high energy saving.
. Suction manifold with ball valves and delivery manifold with non return valves.
. The pressure plant G2 Diva inv can work with the same pressure value (set point) already set up or, for system with high pressure drops, the pressure can be increased depending on the features of the pumps.
. 2 poles asynchronous motor, 50 Hz, 2850 rpm.
. Class F insulation.
. IP44 protection.
. Working voltage: single-phase 230 V, three-phase 400 V.
. External ventilation.
Working Conditions
. Pumped liquid: clean water, non aggressive, without solid particles.
. The pumps can not operate in dry conditions.
. Temperature of pumped liquid: min 5°C - max 30°C.
. Vertical operating position.
. Water feed pressure: min 0,2 – max 3 bar.
. It is essential to connect the system at least to 2 minimum 24 l pressure tanks.
. Maximum number of starts per hour: 20.
. For the choise of automatic pressure plant see page 125 of the Complete catalogue.
. For the consuption at point of demand see Table nr. 2, “Outlet and consumption of the automatic pressure plants” at page 120 of the Complete catalogue.
The picture is simply demonstrative. The pressure plants are also composed by horizontal electric pumps.
