A Pulsation Dampener is an accumulator with a set pre-charge that absorbs system shocks while minimizing pulsations, pipe vibration, water hammering and pressure fluctuations. By minimizing pulsation in the system components like regulators, solenoids, sensors, etc., pumps will see decreased wear and have longer life.
Pulsation dampening provides the added benefit of smoothing the output supplied by many types of pumps, which will enhance system performance and prolong pump life.
