AODD Diaphragm Dampener

Effective Pulsation Control Solution for AODD Pump Systems

An AODD diaphragm dampener is designed to eliminate flow pulsations and pressure fluctuations generated by air-operated double diaphragm (AODD) pumps. By smoothing discharge flow, the AODD diaphragm dampener improves process stability, protects downstream equipment, and enhances overall pump performance.These dampeners are widely used in chemical processing, water and wastewater treatment, pharmaceuticals, food & beverage, and industrial fluid handling applications where consistent flow is critical.

Working Principle of AODD Diaphragm Dampener

An AODD diaphragm dampener operates by absorbing pressure peaks from the pump discharge using a flexible diaphragm and compressed air chamber. As pulsating flow enters the dampener, the diaphragm flexes to absorb energy and releases it smoothly, resulting in steady and uniform flow.This mechanism significantly reduces vibration, noise, and stress on pipelines and valves.

Types of AODD Diaphragm Dampener

Air-Charged AODD Diaphragm Dampener

Uses compressed air to absorb discharge pulsations and is ideal for variable-flow applications.

Maintenance-Free AODD Diaphragm Dampener

Designed with long-life diaphragms and minimal service requirements for continuous operation.
