Pulsation Dampeners

Flexible Membrane (Bladder/Diaphragm):Provides a physical barrier between gas and liquid, allowing for pressure transfer without mixing.

Compressible Gas Chamber:Usually filled with Nitrogen to act as a pneumatic spring that absorbs energy spikes.

Fluid Interface:The wet-end chamber that connects directly to the process piping.

High-Strength Housing:Durable casing in SS316, PVC, or PVDF, engineered to withstand high system pressures.

Charging Valve:Allows for precise adjustment of gas pressure to match specific application needs.

Absorption:As the pump creates a pressure pulse, liquid enters the dampener, compressing the internal gas.

Storage:The gas chamber temporarily stores the energy from the pressure spike, preventing it from traveling down the pipe.

Release:When the pump stroke ends and pressure drops, the gas expands, pushing the liquid back into the line.

Smoothing:This continuous cycle transforms a 'pulsed' flow into a smooth, steady 'laminar' flow profile.

Bladder-Type:Highly flexible and excellent for chemical compatibility; the most common choice for industrial dosing.

Diaphragm-Type:Robust and durable, specifically suited for high-frequency pulsations and sanitary applications.

Piston-Type:Utilizing a metal piston for separation; ideal for ultra-high-pressure hydraulic requirements.

Vibration Control:Eliminates the 'water hammer' effect that causes pipe fatigue and joint leaks.

Metering Precision:Ensures that flow-based sensors and dosing pumps operate with maximum accuracy.

Noise Abatement:Significantly reduces the rhythmic hammering noise common in pump rooms.

Maintenance Savings:Lower wear on valves, seals, and gaskets by providing a consistent pressure environment.

Energy Efficiency:Reduces the 'startup' inertia for the pump at the beginning of every stroke.

Pump Dynamics:Matching the dampener volume to the pump's displacement per stroke.

Material Compatibility:Ensuring the bladder and housing materials are resistant to the process fluid.

Pressure & Temp:Selecting a unit rated for the maximum surge pressure and thermal limits of the system.
