These devices help to absorb pulsations that are created in a high pressure pump system, which are due to the movement of the water from the high pressure pump. Pulsations can reach up to nearly 30% in a triplex pump. These pulsations will reduce the life of the system components including accessories, plumbing, fittings as well as any solid surfaces that are directly attached to the discharge line(s) proceeding from the high pressure pump. Giant offers a range of pulsation dampeners up to 624 GPM (2361 L/min) and up to 10,000 PSI (689 Bar). Common materials are carbon steel, 303 stainless steel and 316 stainless steel. Elastomers are available in Nitrile, Viton and EPDM.

22050
This device is designed to reduce pulsations (pressure fluctuations) that occur with systems that have a positive displacement pump.  Rubber bladder is pre-charged with nitrogen up to 50-60% of the system pressure.  As water passes by the pulsation dampener, it absorbs the pulsations that come from the movement of water in the system.  It is designed to protect pump equipment and piping in the system and can reduce pulsations down to 4%.
