Top Definition
A dampner is a hydraulic device used to reduce pulsations in a hydraulic system.
This differs from a damper which is a hydraulic device used to damp vibrations in a physical system that the hydraulics are connected to.
A Pulsation Dampner is used in a piping system, generally adjacent to the source of the flow or pressure disturbance, which is typically a modulating element like a pump or a flow control valve.

offen the mispronounced version of the word DAMPER. This word is incorrect and the person who uses it should be corrected for their own benefit.
