SURGE TANK
-
accumulates water under pressure to minimize the start-up of the pumps
-
it is essential in the presence of small system leakages
-
absorbs overpressures from the system
-
the minimum tank volume, in liters (for diaphragm models) is approx. equal to 10% of the maximum
capacity of the single pump, expressed in l/min; example in a standard application:
Qmax = 80 l/min
V = 80 x 10% = 8 liters
rounded up to commercial size
-
pre-charge: a. 50% of the working pressure: e.g.:
Pset = 4 bar
Ppre-charge = 2 bar
