How Pulsation Dampeners Work

A pulsation dampener uses a flexible diaphragm to separate a liquid chamber from a compressed air chamber. A rod connected to the center of the diaphragm activates the air inlet and exhaust, which automatically adjusts the air chamber pressure. This maintains the diaphragm in the mid-range of the stroke to eliminate flow pulsation and pressure spikes.
