FlowGuard pulsation dampeners are specialized hydro-pneumatic devices used in fluid handling systems

Key Benefits of FlowGuard Pulsation Dampeners

1. Smooth & Continuous FlowThey absorb pulsations from reciprocating or dosing pumps, creating a steadier, more uniform flow of fluid through the system. This improves process performance in applications like metering, mixing, and injection systems.

2. Reduces Pressure Fluctuations and SurgesDampeners minimize peaks and troughs in pressure that can occur with each pump stroke, reducing hydraulic shock and helping maintain system stability.

3. Protects Pumps and EquipmentBy smoothing pressure variations:

• Mechanical stress and vibration on pumps, piping, valves, and instruments are reduced.

• Pump motors and gearboxes experience less overload, extending their service life.

4. Reduces Vibration and NoisePressure pulsations often cause pipe vibration and audible noise. Dampeners dramatically lower both, leading to quieter and safer operation.

5. Prevents CavitationIn systems with long suction lines or poor suction conditions, pressure can drop below vapor pressure, causing cavitation. Dampeners help maintain steadier pressure and reduce this risk.

6. Improves Measurement and Process AccuracySteadier flows improve the accuracy of instruments like flow meters and pressure sensors, which might otherwise fluctuate with pressure pulsations.

7. Lower Maintenance & Operating CostsSmoother flow and fewer pressure-induced stresses help reduce wear and breakdowns — cutting maintenance demands and downtime.

🛠️ How They Work (Quick Overview)

FlowGuard dampeners usually contain a gas-charged chamber separated from the fluid by a flexible membrane. When a pressure pulse arrives, part of the fluid compresses the gas; as pressure drops, the gas expands back into the fluid, smoothing out the flow and pressure in the line
