DJ PulsationDampeners
Designed to eliminate discharge pulsation generated by air-operated double diaphragm pumps, providing smoother flow while reducing pipeline vibration, water hammer and system noise.
Automatic
Self-adjusting air pressure for changing operating conditions.
Manual
Cost-effective pre-charge design for stable processes.
Protect the Whole Fluid System
Installing a pulsation dampener helps protect pipelines, valves, instruments and downstream equipment, extending service life and improving overall system reliability.
Smoother Flow
Reduces discharge pulsation and helps create a more stable, continuous liquid flow.
Less Vibration
Helps reduce pipe vibration and mechanical stress in the whole pipeline system.
Water Hammer Control
Minimizes sudden pressure shocks that may damage valves, instruments and fittings.
Lower Noise
Improves system stability and reduces operating noise in pump transfer lines.
Choose TA or DA According to Your Working Conditions
DJ offers both automatic and manual pulsation dampeners to suit different pump sizes, flow rates and pressure fluctuation conditions.
Automatic Pulsation Dampener
Ideal for high-flow applications and frequently changing operating conditions.
Manual Pulsation Dampener
A cost-effective solution for smaller pumps and stable operating processes.

Simple Selection Guide
Small Pump + Stable Process
DA Series is suitable for smaller pumps and stable applications where manual pre-charge adjustment is acceptable and cost control is important.
Large Flow + Changing Pressure
TA Series is suitable for larger pumps, frequent pressure fluctuations and applications where automatic self-adjustment can reduce maintenance work.
Industrial Applications
DJ Pulsation Dampeners are widely used in fluid transfer systems where stable discharge flow is required.
