A pressure pulsation dampener particularly adapted for use in connection with positive displacement reciprocating plunger pumps comprising a pressure vessel adapted to be connected to the pump discharge flow line and having a liquid volume capacity sufficient to reduce the flow velocity of the liquid entering the vessel by approximately 85%. The liquid volume capacity of the tank is preferably at least 5% of the discharge liquid volume flow rate of the pump wherein the units of volume are the same and the unit of time of liquid flow rate is the minute. The tank includes a gas volume portion formed by a bulkhead in the tank, an inflatable flexible bladder disposed in the flow path of the fluid flowing through the pulsation dampener or an elongated tube in which a gas-liquid interface is maintained. The pulsation dampener is particularly adapted for use in hydraulic systems subjected to a substantial discharge static head imposed on the pump and resulting from a vertical change in elevation of the discharge flow line.
