5.3 APP S 674 21-38 flow curves at max pressure
The curves above also show that the flow can be
changed by changing the rotation speed of the
pump. The flow/rpm ratio is constant, and the
“required “ flow can be obtained by changing the
rotation speed to a corresponding value. Thus,
the required rpm can be determined as:
Required flow × Typical rpm
Required rpm =
Typical flow
