Pressure Pulsation Dampeners, Surge Suppressors, and Accumulators

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: Pulsation dampeners must be able to address pressure changes with velocities between a thousand and two thousand meters per second). There are accumulators for flow fluctuation, that intercept pressure pulsation, these are called "dual purpose" dampeners. Dual purpose pulsation dampeners are defined also as an accumulator that will address flow fluctuation, and thereby prevent excessive acceleration head pulsation (as is only experienced with reciprocating pumps), and intercept/dissipate pressure waves. There are also pure accumulators, for flow fluctuation. The response characteristics of these devices is often not published.
