There are both PRESSURE PULSATION and FLOW FLUCTUATION, DAMPENERS
There are dampeners for pressure pulsation. A dampener is defined as a device which will address pressure wave activity. IE A dampener must be able to address pressure changes with velocities between a thousand and two thousand meters per second.
Dampener - Accumulators
There are accumulators for flow fluctuation, that also intercept pressure pulsation, these are called "dual purpose" dampeners. A dual purpose dampener is defined as also being an accumulator that will address flow fluctuation, and thereby prevent excessive acceleration head pulsation, (as is only experienced with reciprocating pumps,) and also intercept and dissipate pressure waves (that are sometimes called acoustics).
Pure Accumulators
Then there are purely accumulators, only for flow fluctuation. The response characteristics of these devices is often not even published!
Dual Purpose Pressure Pulsation Dampeners / Volume Flow Accumulators
These are "Horses for Courses"
I Types with elastomer membranes where synthetic rubbers suit your liquids. Both low and high pressure ranges.
II Types with PTFE "FlexFlon" - "TEFLON" DuPont for your more aggressive liquids. Both high and low pressure ranges
