The diagram shows pressure dierences across
the ushing valve:
4. Flushing valve
5. Flow at dierent rpm Using the diagram shown below, it is easy to
select the pump which ts the application best if
the ow required and the rotation speed (rpm) of
the pump are known.
Furthermore, this diagram shows that the ow
can be controlled by changing the rotation
speed of the pump. The ow/rpm ratio is
constant, and the “required“ ow can be
obtained by changing the rotation speed to a
corresponding value. Thus, the required rpm can
be determined as:
Required ow × Rated rpm
Required rpm =
Rated ow

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