1. INSTALLATION
1.1. Operation principle
The pulsation dampener’s main function is to remove pressure variations on the discharge of
the pump. The dampener works actively with compressed air and a diaphragm, automatically
setting the correct pressure to minimise the pulsations.
The air pressure supplied to the dampener is the same as the one supplied to the pump. The
medium flowing through the dampener affects the diaphragm, which by means of the
compressed air on the air side compensates the fluctuations of pressure in the discharge line.
The air concentrated in the dampeners block works as a spring for the medium flowing through
the dampener.
When operating, dampener does not consume compressed air. It is only consumed during
setting phase, when pump duty point is being changed.
