A pulsation dampener smooths the pressure and flow surges produced by reciprocating, diaphragm and metering pumps. Power Energy supplies pulsation dampeners in Saudi Arabia and the GCC to reduce pipe vibration, protect instruments and give a steadier flow. Tell us the pump and the duty and we will help you size the right dampener.
How a Pulsation Dampener Works
A dampener holds a cushion of gas, usually nitrogen, behind a flexible diaphragm or bladder. When the pump delivers a surge, the cushion compresses and absorbs it. When the pump flow drops, the cushion expands and releases liquid back into the line. The result is a much smoother flow downstream.
Why Fit a Pulsation Dampener
- Reduces pipe vibration and noise
- Protects gauges, flow meters and valves from pressure spikes
- Gives a steadier, more accurate flow
- Reduces water hammer and wear on the pump and the pipework
Pumps That Need Dampeners
- Reciprocating pumps (piston and plunger)
- Air-operated diaphragm pumps
- Metering and chemical dosing pumps
How a Dampener Is Sized
Sizing depends on the pump type, the volume delivered per stroke, the operating pressure, the fluid and how much residual pulsation the system can tolerate. The gas pre-charge must be set to suit the system pressure, following the manufacturer’s instructions. Send us the pump data and we will size it with you.

What We Need to Recommend a Pump
- The fluid, its viscosity and temperature
- Flow rate and discharge pressure
- Solids content and abrasiveness
- Suction conditions and installation (indoor, outdoor, hazardous area)
- Duty cycle and any project or client specification

Frequently Asked Questions
What is a pulsation dampener?
A pulsation dampener is a vessel with a gas cushion behind a diaphragm or bladder that absorbs the flow and pressure surges from a pump and smooths the flow.
Which pumps need a pulsation dampener?
Reciprocating pumps, air-operated diaphragm pumps and metering pumps produce pulsating flow and normally benefit from one.
What does a pulsation dampener do?
It reduces pipe vibration, pressure spikes and noise, protects instruments and gives a steadier flow.
How do you size a pulsation dampener?
Sizing uses the pump type, the volume per stroke, the operating pressure, the fluid and the residual pulsation allowed. The gas pre-charge is set to suit the system pressure.
Can Power Energy help me select a pulsation dampener in Saudi Arabia?
Yes. Send us your pump data and system pressure and we will recommend and size a suitable dampener.
