Operation principal
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 concen
-
trated in the dampeners block works as a spring for the medium flowing through the dampener.
Before starting the pump and dampener.
- Make sure the pump is installed according to the installation instruction.
- When installation is new or re-installed, a test run should be conducted to make sure the
dampener operates normally and does not leak.
- When installation is new or re-installed, check the dampener housing nut tightening torque.
After approx. 1 week of operation, the torque should be checked again. This is important
to prevent leakage.

Health & Safety
The dampener must be installed according to local and national safety rules.
The dampeners are constructed for particular applications. Do not use the dampener on applica-
tions different from that for which it was sold without consulting Tapflo AB to ascertain its suitability.
