Pulsation Dampener - Graphic Example

The pump type with which these dampeners work, suffer inefficiency due to process liquid compressibility at temperature. This phenomenon, according to pump manufacture technical bulletins, produces a velocity jump shock at the commencement of each suction and each discharge stroke. Shock pressure waves in liquid typically travel at 1400 meters per second. Twice the velocity of a bullet. In order to address these shocking pulses they must be caused to enter the dampeners. To ensure the entry of the pulses, and to isolate the system from them, the Flexorber pulsation dampeners have to at least have an entry and an exit connection. For use with multiple diaphragm pump heads, the piping base blocks, which intercept and prevent pulsation by-passing, may have up to 5 connection. One to each pump head and on to the system.
