Abstract: To inhibit damage to or failure of the bladder within a bladder-type pulsation dampener, an internal passage of a bladder saver device carrying pumped fluid from the pulsation bleed plate mounted within the internal passage and movable between a first position in which the pulsated fluid flow is unencumbered by the bleed plate and a second position in which the pulsated fluid flow is restricted by the bleed plate.

Abstract: A pulsation dampener includes a quantity of liquid reactive fluid (e.g., about 20 gallons) contained within a flexible diaphragm and separated from fluid from an external pumped fluid flow. The quantity of liquid reactive fluid is selected to dampen pressure pulses within the external pumped fluid flow. The pulsation dampener is configured to accommodate thermal expansion of the quantity of liquid reactive fluid by one or more of including a quantity of compressible foam within the flexible diaphragm, allowing for a space between the flexible diaphragm when holding the quantity of the liquid reactive fluid and a body of the pulsation dampener, or providing a reset pressure relief valve.
