The diagram shows pressure differences across
the flushing valve:
4. Flushing valve
5. Flow at different rpm
Using the diagram 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, this diagram shows that the flow
can be controlled 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

5. Flow at diff erent rpm
Using the diagram shown below, it is easy to select the pump which fi ts the application best if the fl ow required and the rotation
speed (rpm) of the pump are known.
Furthermore, this diagram shows that the fl ow can be changed by changing the rotation speed of the pump. The fl ow/rpm ratio is
constant, and the “required “ fl ow can be obtained by changing the rotation speed to a corresponding value. Thus, the required rpm
can be determined as:
Required fl ow × Rated rpm
