Diaphragm Type Dampener

Reliable Pulsation Control Solution for Dosing & Pumping Systems

A diaphragm type dampener is designed to absorb pressure pulsations and flow fluctuations generated by positive displacement pumps such as dosing pumps, diaphragm pumps, and plunger pumps. By smoothing discharge flow, it protects pipelines, instruments, and valves while improving system efficiency and operational stability. Diaphragm type dampeners are widely used in chemical dosing systems, water treatment plants, wastewater treatment facilities, and industrial process applications where steady and controlled flow is required.

Working Principle of Diaphragm Type Dampener

A diaphragm type dampener operates using a flexible diaphragm that separates the process fluid from a gas or air cushion. When pulsating flow enters the dampener, the diaphragm flexes to absorb pressure peaks and releases the fluid gradually, resulting in smooth and uniform flow.This mechanism significantly reduces vibration, noise, and mechanical stress on the system.

Types of Diaphragm Type Dampener

Gas-Charged Diaphragm Dampener

Uses a pre-charged gas cushion for effective pulsation absorption in high-pressure applications.

Air-Charged Diaphragm Dampener

Utilizes compressed air for reliable pulsation control in low to medium pressure systems.
