MLPD38 | Pulsation Dampener, Smoothing Flow

MLPD38 – Pulsation Dampener – 3/8″ Port

The AR MLPD38 pulsation dampener is engineered by Annovi Reverberi to stabilize pressure, reduce vibration, and maintain consistent flow in high-performance pump and fluid-handling systems. By absorbing hydraulic shock and minimizing pressure spikes caused by piston or plunger pump cycles, it protects sensitive components and ensures smooth, efficient system operation.

Precision Pressure Stabilization

Using an internal compressible chamber, the MLPD38 cushions pulsations and releases energy gradually, resulting in steady flow and even discharge pressure. This reduces noise, vibration, and mechanical stress throughout the system, extending the life of pumps, hoses, seals, and fittings.

Durable, Corrosion-Resistant Construction

• Built from high-quality, corrosion-resistant materials
• Withstands high-pressure cycles and temperature fluctuations
• Resistant to cleaning agents and mild chemicals
• Engineered for long service life in industrial and commercial environments

MLPD38 Compact, Easy-to-Install Design

• 3/8″ threaded port for secure, leak-free connection
• Simple integration into pressure washers, sprayers, or fluid transfer lines
• Mountable vertically or horizontally
• Ideal for tight system layouts and retrofit installations

How the MLPD38 Works

• Uses an internal gas or air pre-charge to absorb incoming fluid pulses
• Dampens pressure spikes to maintain stable output pressure
• Reduces cavitation, turbulence, and vibration-related noise
• Improves spraying consistency and overall pump efficiency

Performance Benefits

• Smoother flow at the nozzle or outlet
• Enhanced cleaning efficiency and operator comfort
• Reduced stress on system components
• Extended equipment lifespan and reduced downtime
