WORKING HEAD
The graph below illustrates the useful head values (
kPa
) depending on the flow rate in (
liters/second
). The operating range is
delimited by the minimum and maximum values given in the next table.
Useful head is the one at the outlet of the standard pumping module minus all the loss of head values of the unit.
