How the PD8100 Pulsation Dampener Works

Reciprocating compressors and piston pumps generate rapid pressure fluctuations that travel through the process line and reach the pressure gauge. These pulsations cause pointer flutter, unstable readings, and increased mechanical wear inside the instrument.

The PD8100 Series pulsation dampener regulates and smooths these pressure pulses using an adjustable internal valve mechanism. By controlling the flow before it reaches the gauge, the dampener minimizes vibration, improves reading stability, and protects sensitive internal components from excessive strain.

Installing the dampener directly below the pressure gauge ensures that pulsation is absorbed at the point of measurement, providing accurate, repeatable readings even in high-frequency or high-pressure industrial applications.

This controlled dampening effect enhances system reliability, extends the service life of pressure instruments, and supports safe and efficient operation in marine, oil & gas, and industrial environments.
