Boosterset composed by 2 vertical Multistage centrifugal pumps in AISI 304 stainless steel. Ideal for pumping non-loaded fluid; pressurisation systems; irrigation; drinking or glycol water; water treatment; food industry; heating and air conditioning; washing systems. These pumps are available with overlapping or in-line deliveries and with threaded or flanged versions.
 
Fully automatic booster sets for water supply equipped with 2-3 fixed speed pumps, control panel, pressure switches, all fixed on a single frame for easy installation. These booster sets are suitable for water network supply in housing complexes, offices, hotels, shopping centers, industrial plants and for irrigation. It is recommended the installation of a membrane tank. 
 
FEATURES 
• Suction galvanized steel manifold with non-return and isolation valves 
• Delivery galvanized steel manifold with pressure gauge, isolation valves and pressure switches 
• Base frame in painted steel 
• Electronic or electromechanical panels for pump’s control and protection 
• Pressure tanks available on request, as accessory 
 
FUNCTIONING 
As soon as pressure drops below the minimum pressure set on a pressure switch, the first pump starts automatically. If water demand further increases, the second pump (and third if present) will run until the pressure rises above the maximum pressure set on the pressure switches. When demand ends, the last pump fills up the membrane tank and then turns off. All the pumps follow cycling changeover for equal work distribution. In case of one pump failure, the other pumps would continue to operate.
