At Cannon Water Technology, we offer the finest quality pulsation dampeners that effectively minimize pulsations and guarantee stable discharge flow and pressure. With us, you can get the most appropriate model based on the type of liquid being pumped, piping configuration, pressure and flow rate, and mounting requirements.
Working Principles of Pulsation Dampeners for Dosing Pumps
Here's a step-by-step breakdown of how pulsation dampeners work to stabilize fluid flow.
- Pressure equalization: Pulsation dampeners apply balanced pressure to each pump stroke, especially during low-pressure points, ensuring consistent operation.
- Absorbing pulsations: As a diaphragm pump creates pressure pulsations, the dampener's internal component (often a flexible bladder or diaphragm) expands and contracts, responding dynamically to changes in pressure.
- Smoothing peaks and troughs: During high-pressure peaks, the dampener absorbs excess energy; during low-pressure troughs, it releases stored energy, thus almost equalizing flow variations.
- Reducing fluctuations and noise: By minimizing pressure fluctuations, dampeners reduce vibrations and noise, enhancing equipment stability and performance while also extending the operating life of the pump.
Components of Pulsation Dampener
All types of pulsation dampeners may vary in size, shape, and materials, but they have some common parts. These parts help keep the flow of liquid steady, which is important for the system's stability and longevity. The main components include:
- Pressure vessel: The pressure vessel is the primary part of the pulsation dampener. It consists of different components and can withstand the pressures experienced during pumping. The materials and design of the pressure vessel are key to making the dampener safe and durable.
- Diaphragm: In a pulsation dampener, the diaphragm separates the liquid from the dampening element and the environment. It has flexible properties that enable the inner volume of the pulsation damper to differ. At Cannon Water Technology, you have the option to choose among different diaphragm materials, such as EPDM or FFKM, to achieve chemical compatibility.
- Dampening element: The dampening element is a solid part located just outside the diaphragm. It absorbs and reduces pressure changes. The special material can expand and contract, which helps counteract pressure spikes and keeps the flow rate steady and consistent.
- Inlet and outlet connection: These connections attach the pulsation dampener to the pump system. It's important to size and position these connections correctly to reduce pulsations and create an effective dampening effect.

How to Choose the Right Pulsation Dampener?
When selecting the right pulsation dampener, consider these key factors.
- Ensure the dampener's capacity matches your system's flow rate and maximum pressure for effective performance.
- Choose materials for the body, diaphragm, and other components that can resist the specific fluids in your application.
- Assess the purpose, such as reducing noise or maintaining dosing accuracy, to determine the dampener's size and type.
- Consider environmental factors like temperature and pressure fluctuations.
- Opt for a design that is easy to maintain and service in your system setup.

Got Questions? We Have the Answers!
- Can a pulsation dampener handle multiple fluids in the same system?
Yes, but it requires a diaphragm material compatible with all fluids to avoid degradation and ensure optimal performance.
- Is a pulsation dampener suitable for both high- and low-pressure applications?
Yes, but dampener size, pressure rating, and diaphragm material must align with the application's pressure requirements for correct functioning.
- What is the impact of gas type and pressure on the dampener?
Typically, nitrogen is used, and its pressure level is critical for dampening efficiency. Incorrect gas pressure can reduce dampener effectiveness.
- How do pulsation dampeners affect dosing pump accuracy?
By minimizing flow fluctuations, dampeners stabilize discharge flow, enhancing dosing accuracy and reducing calibration frequency.
