About Pump Pulsation Dampeners
CONTROL PIPE RATTLE AND PRESERVE EQUIPMENT PERFORMANCE WITH PULSATION DAMPENERS
What is a Pulsation Dampener?
A pulsation dampener is a piece of equipment capable of reducing pulsations and vibrations, often occurring on the discharge side of reciprocating positive displacement pumps. It’s designed to reduce flow variations, thereby playing an important role in producing a precisely non-pulsed flow rate.
The dampener can be used with various Positive Displacement Pumps, such as Diaphragm Pumps, Peristaltic Pumps, Dosing Pumps, and Piston Pumps, enhancing the fluid flow’s reliability.
The pulsation dampener’s membrane contains a compressible gas, creating a pneumatic damping cushion that absorbs the energy from pulse waves. This mechanism allows for an even flow downstream, ensuring smooth and consistent fluid delivery.
Pulsation Dampener Applications
Pulsation Dampeners are essentially required in various applications where smooth, consistent flow is integral to the operation. Not only do pump pulsation dampeners result in cost-savings and prevent pump damage but they also:
- Limit pump vibrations, which preserves and improves the pump’s performance
- Maintaining the efficiency of the pump’s filters
- Avoiding equipment defects caused by water hammer, or a phenomenon where a sudden change in flow rate inside the pipes creates pressure peaks
- Reducing noise pollution
- Improving fluid flow overall
- Reduce the load on the pump, enhancing its performance and lifespan.

How Does a Pulsation Damper Work?
A pulsation damper is a device that plays a crucial role in pump systems. It ensures a smooth and uninterrupted flow of fluid, regardless of the operating pressure. But how does it work?
Installation
Compressed Air Generation
- The process begins with the pump's operation. As the pump works, the connected compressor generates pressure pulses. These pulses are essentially bursts of energy that can cause the fluid flow to become uneven or 'pulsed'.
Introduction of Compressed Air
- These pressure pulses aren't wasted. Instead, they're directed into a pulsation dampener, typically found attached to the pump. Inside the dampener, there's a special chamber known as a counter-pressure chamber. The compressed air from the pump is introduced into this chamber.
Creation of Damping Cushion
- Once inside the counter-pressure chamber, the compressed air forms a 'pneumatic damping cushion'. This cushion is behind a membrane within the damper.
Self-adjustment
- This damping cushion has a unique characteristic - it can self-adjust. This means it can change its form or pressure in response to the stress exerted by the pressure pulse of the fluid generated by the pump.
Pulsation Reduction
- As the damping cushion self-adjusts, it effectively reduces the pulsations caused by the pressure pulses. This results in a more continuous and steady fluid flow, regardless of the operating pressure.
A pulsation damper takes the pressure pulses generated by the pump, creating a self-adjusting cushion that smooths out these pulses and hence ensures a smooth and steady flow of fluid. This process is crucial for the efficient operation of many pump systems.
Risks Deriving from Fluid Pulsations
Fluid pulsations within hydraulic systems can lead to a challenging issue called water hammer. It occurs when there is a sudden surge of pressure due to abrupt changes in flow rate or the immediate closure of a valve. Depending on the pipeline’s size, fluid speed, and density, a water hammer can cause extensive damage to your system.
But Hunter Pumps has the perfect solution – our pulsation dampers. These devices are designed to protect your system from water hammer and vibrations. The standout feature of our dampers? They automatically adjust to your pump’s operating conditions, providing optimal protection without any hassle.
Rely on Hunter Pumps for uncomplicated and worry-free preservation of your hydraulic systems.
