In real industrial applications, using only a pulsation dampener or only a back pressure valve is often not enough. Combining both components is the most effective way to achieve stable pressure, smooth flow, and accurate dosing.
A back pressure valve maintains pressure, but it cannot eliminate high-frequency pulsations generated by metering pumps.
Without a pulsation dampener, the system may still experience:
Pressure spikes
Pipe vibration
Fluctuating flowmeter signals
This is where the pulsation dampener becomes essential.
When a pulsation dampener is installed directly after the metering pump:
Pressure spikes are absorbed before reaching the valve
Flow entering the back pressure valve becomes smoother
The back pressure valve can regulate pressure more accurately
The result:
More stable system pressure
Improved dosing accuracy
Longer service life of valves and pipelines
Typical configuration (from pump discharge):
Metering Pump → Pulsation Dampener → Back Pressure Valve → Downstream System
This arrangement ensures both flow smoothing and pressure stabilization.
Stable pressure and smooth flow are essential for precise chemical dosing.
Lower vibration and pressure shock significantly reduce mechanical stress on pipes, fittings, and instruments.
Especially suitable for continuous operation and demanding industrial environments.
Chemical dosing systems
Water and wastewater treatment
Oil & gas chemical injection
Pharmaceutical and fine chemical processes
In these industries, the combined use of pulsation dampeners and back pressure valves is a standard engineering solution.
A pulsation dampener stabilizes flow, while a back pressure valve stabilizes pressure.Together, they unlock the full performance potential of metering pump systems.
