Description pump 2ultra sv-sl with variable speed driver
Highly efficient pressure boosting system with 2 vertical stainless steel multistage pumps with inline (SL) or overlapped (SV) suction/delivery for fully automatic water supply. It includes IPFC or EPIC variable speed drives to control the pumps by distributing the work based on the pressure set and real working time of each pump also assuring dry running protection.
COMPOSITION OF THE PRESSURIZATION GROUP
– Monobloc electric pumps with horizontal or vertical axis
– Steel suction and discharge manifolds, threaded and galvanized, with sleeves for membrane deposits in the discharge line.
– Group base and support for electrical panel in galvanized steel.
– A check valve for each electric pump mounted on suction.
– Ball valves with union, one mounted on the suction line and the other another in the impulsion of each electric pump.
– Manometer with radial connection.
– One or more VSDs configured in the characteristics of the connected pump.
– Pressure sensors (one for each VSD) installed on the intake manifold. sending and directly connected to the variable speed drives.
– On request: membrane autoclave tanks, blocking valves.
