The pumps are operated by means of a frequency converter. This enables
speed control from 500 to 1500 rpm. The pumps can be switched using a
key switch.
The possible speed depends on the NPSH value. The NPSH value depends
on the pre-pressure of the container and the back pressure of the
system. The back pressure of the system is significantly influenced by
the test object and its settings.
Adjustments are made by adjusting the pressure on the container.
