Pulsation Dampener

A pulsation dampener typically works by using a gas cushion (nitrogen) inside the dampener. When pressure spikes occur in the pipeline, the gas compresses and absorbs the shock. When pressure drops, the gas expands and stabilizes the flow. This continuous buffering action reduces:

• vibrations
• pipeline noise
• water hammer effects

damage to instruments and valves

Pulsations are caused due to the pumping mechanism itself. In reciprocating pumps, fluid delivery happens in strokes, not in continuous flow. This leads to:

• frequent pressure fluctuations
• surge and shock waves
• vibration in pipeline
• stress on fittings and valves

A pulsation dampener is the best engineered solution to control these issues.

Pulsation dampeners are usually installed:

• on the pump discharge line (most common)
• near the pump outlet
• sometimes on suction line (if required)
• close to sensitive equipment like flow meters, pressure transmitters and dosing valves

Correct positioning improves dampening performance and extends system life.

Both use gas cushioning, but the purpose differs:

Pulsation Dampener

• designed mainly to absorb pressure spikes
• reduces vibration and pulsation in pump systems
• improves instrument accuracy and piping safety

Accumulator

• designed mainly for energy storage and pressure maintenance
• supports emergency pressure during failure
• acts like a backup fluid source

In reciprocating pump circuits, pulsation dampener is a must for smooth operation.

Using a pulsation dampener helps to:

• reduce pressure surges and hammering effects
• minimize pipeline vibration and fatigue
• protect control valves, sensors, meters and fittings
• improve pump efficiency and component lifespan
• stabilize flow for accurate metering & injection
• compensate minor leakages and pressure fluctuations

This directly reduces breakdowns and maintenance cost.

Petronash pulsation dampeners are available in:
Volume range: 0.05L to 50L

This wide range supports compact dosing systems to large industrial pumping and hydraulic circuits.

Petronash pulsation dampeners are designed for very high-pressure operation:
Max Operating Pressure: 690 Bar(g)

This makes them suitable for demanding applications including oil & gas chemical injection skids and high-pressure pumping systems.

Petronash provides a wide range of materials to match chemical compatibility and process conditions:
