Suppose you need to boost a pressure up to say 3 Bar (suppose as dictated by the manufacturer). Every 27" water column = 1 psi or every 2'-3" = 1 psi.
3 bar x 14.5 = 43.5 psi x 2.3 = 100 ft head on the pump.
Depending on frictional losses , vertical height, length of travel etc ., you have to add all the heads. Say you get 50 ft. This then becomes 150 ft head of pump vs the flow Gpm/M3/hr. 150 ft head/2.3 = 65.2 psi/14.5=4.5 bar. So you can easily get the dictated 3 bar required.
The above was an example. You have to arrive at your total head required to select a boosting pump.
