Description pump 2ultra
Stainless steel multistage horizontal pumps. Pumping of clean non-loaded fluids; pressurizing system; irrigation; drinking and glycol water; water treatment; heating and air conditioning; washing system.
Line of automatic pressurization units
consisting of 2 pumps (2 ULTRA) or 3 pumps (3 ULTRA) with pressure switch control
COMPOSITION OF THE PRESSURE BOOSTER UNIT
– Horizontal or vertical axis monobloc electric pumps.
– Suction and delivery manifolds in steel, threaded and galvanized, with sleeves for delivery membrane tanks.
– Group base and support for electrical panel in galvanized steel.
– A check valve for each electric pump mounted on the suction side.
– Ball valves with union mounted one in suction and one in delivery of each electric pump.
– Pressure gauge with radial connection.
– Electrical cabinet.
– Pre-set pressure switches mounted on the delivery manifold and directly connected to the electrical panel.
– On request: membrane autoclave tanks, shut-off valves.
GROUP ELECTRICAL PANEL COMPOSITION
