When using the diagrams shown below, it is easy
to select the pump which fits the application
best if the flow required and the rotation speed
(rpm) of the pump are known.

Furthermore, these diagrams shows 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 × Rated rpm
Required rpm =
Rated flow
