AODD Pulsation Dampener

AODD Pulsation Dampener

An AODD Pulsation Dampener is an essential accessory used with Air Operated Double Diaphragm (AODD) pumps to minimize flow and pressure pulsations generated during pump operation. AODD pumps inherently create pulsating flow due to their reciprocating diaphragm action, which can cause vibration, noise, pressure surges, and stress on piping systems. A pulsation dampener helps stabilize the flow, ensuring smooth and consistent fluid transfer.Our AODD pulsation dampeners are designed to absorb pressure fluctuations and deliver steady discharge flow, improving overall system efficiency and protecting downstream equipment such as flow meters, dosing systems, valves, heat exchangers, and pipelines. They are widely used in chemical processing, water treatment, paint & coating, pharmaceuticals, food & beverage, oil & gas, and mining industries.The dampener works by using a flexible diaphragm or bladder with a compressed air cushion that absorbs pulsation energy and releases it gradually. This reduces hydraulic shock, minimizes pipe vibration, and enhances pump and system longevity. Properly sized dampeners can reduce pulsation by up to 90%, resulting in quieter and safer operation.
