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. 1 bar less than the working pressure: e.g.:
Pset = 4 bar


Ppre-charge = 3 bar
