Pulsation dampener
The pulsation dampener can be installed both in the
suction or discharge line for reducing pressure surges,
thereby ensuring a steady flow.
particularly suitable for long discharge lines and/or lines
with a small diameter.
Installed in the discharge line, the dampener can be
used to optimize dosing accuracy and to protect the
pump and discharge line against pressure surges.
Depending on the system pressure, it may be neces-
sary to install a back-pressure valve after the dampener
to optimize its function.
Maximum pressure: 145 psi (10 bar).
