TECHNICAL FEATURES
Closed Valve Pressure 125% of the nominal pressure
Maximum Load The pressure when the flow rate increases to 140% should not be less than 70% of the nominal pressure
Back Up In two-pump systems, each pump should ensure predefined flow rate and pressure alone. It can be selected in a manner to cover 50% of each pump's nominal flow rate on the systems with three pumps
Suction Line Water Flow Rate Flow rate is 1.8m/s in positive suction and 1.5 m/s in negative suction
