Basics of Pulsation Vessels
Definition and Function:
Pulsation vessels, also referred to as pulsation bottles, are specially designed containers integrated into industrial fluid systems to mitigate pressure fluctuations. Their primary function is to absorb and dampen pulsations, surges, and vibrations generated by dynamic equipment such as pumps, compressors, or reciprocating engines. By acting as a buffer, pulsation vessels help maintain a more constant flow and pressure within the system, ensuring smoother operation and reducing stress on downstream components.
Components and Construction:
Pulsation vessels typically consist of a cylindrical or spherical shell made from materials capable of withstanding high pressures and corrosive environments commonly found in industrial applications. The vessel may include additional components such as inlet and outlet connections, pressure relief valves, gauges, and mounting brackets.

Working Principle:
The working principle of pulsation vessels revolves around the concept of volume elasticity and compressibility. When fluid flow experiences sudden changes in velocity or direction, it creates pressure fluctuations within the system. Pulsation vessels exploit the elasticity of trapped air or other compressible mediums inside the vessel to absorb these pressure variations. As the fluid pressure increases, the compressible medium compresses, storing potential energy. Conversely, when pressure decreases, the compressed medium expands, releasing stored energy to maintain system pressure within acceptable limits. This cyclical process helps dampen pulsations and fluctuations, promoting smoother fluid flow and reducing the risk of damage to system components.

Types of Pulsation Vessels
Bladder-type Pulsation Vessels:
Bladder-type pulsation vessels feature a flexible bladder or membrane housed within a pressure vessel. The bladder separates the fluid from a compressed gas (typically nitrogen) charge, allowing for the expansion and contraction of the gas as fluid pressure changes. This design ensures that the fluid remains isolated from the gas, preventing contamination and maintaining system integrity. Bladder-type pulsation vessels are known for their compact size, high efficiency, and versatility, making them suitable for a wide range of industrial applications.
Diaphragm-type Pulsation Vessels:
Diaphragm-type pulsation vessels employ a flexible diaphragm to separate the fluid from a compressible gas charge. As fluid pressure fluctuates, the diaphragm flexes inward or outward, accommodating changes in volume within the vessel. This design provides effective pulsation dampening while minimizing the risk of fluid leakage or contamination. Diaphragm-type pulsation vessels are valued for their reliability, durability, and ease of maintenance, making them popular choices for critical industrial processes where fluid purity and system integrity are paramount.
Piston-type Pulsation Vessels:
Piston-type pulsation vessels utilize a movable piston or plunger to separate the fluid from a gas or liquid charge. As fluid pressure fluctuates, the piston moves within the vessel, compressing or expanding the gas or liquid charge to accommodate changes in volume. This design offers precise control over pressure regulation and pulsation damping, making piston-type pulsation vessels well-suited for applications requiring high-pressure stability and dynamic response. However, piston-type vessels may be more complex and costly to manufacture and maintain compared to bladder or diaphragm-type vessels, limiting their suitability for certain industrial applications.
Considerations for Selecting Pulsation Vessels
