4.2 Operating curves
4.2.1 How to read the diagrams:
The following diagrams show 2 curves, one continuous and one with a dotted line.
The continuous line shows the water owrate at a specic operating pressure. The dotted line shows the motor oil pressure.
Example: Diagram of a pump (Code 9700502x) with a motor of 7,2 cm
3
:
To obtain a water owrate equal to 340 l/min with a pressure of 5 bar (1), the pump will have to be powered by an oil circuit that can guarantee a
owrate of 26,5 l/min with a pressure of about 128 bar (2).
