A pressure pulsation trap is provided. The pressure pulsation trap includes a channel extending from an inlet to an outlet, and a plurality of branches extending from the channel, each of the branches having different lengths than one another. The different lengths are configured such that the branches attenuate noise and/or vibration over a range of operating frequencies.

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.

A gas charged cartridge for use with a cylinder to form a pulsation control dampener is provided. The cylinder receives a fluid for the pulsation control dampener. The gas charged cylinder can include a head, a plug, an elastomer composite, and a perforated retaining sleeve. The head is located on a first end of the gas charged cartridge. The plug is located on a second end of the gas charged cartridge. The elastomer composite connects the head to the plug. The perforated retaining sleeve is affixed to the plug surrounding the elastomer composite.

A fluid damper includes a body defining a fluid chamber and a first opening. The body is formed by a first cover and a second cover joined along an axial direction. A damping device is suspended inside the fluid chamber to damp pressure pulsations. The damping device is constrained by a peripheral edge. The damping device divides the fluid chamber into first and second sub-chambers. The first cover has a first wall portion into which a second wall portion of the second cover is received. A hermetic seal is formed between the first and second wall portions. The second cover has a terminal edge lying within the first wall portion of the first cover, the terminal edge being segmented into a plurality of fingers that cooperate with a ledge surface of the first cover to pinch the peripheral edge of the damping device.
