A pulsation control device coupling a reciprocating pump with either suction or discharge piping and having a generally spherical or cylindrical interior chamber includes a curved baffle with a pressure drop device (e.g., a choke) separating the interior chamber into two volumes and forcing fluid flow through the pressure drop device. The effective fluid passage provided by the pressure drop device is smaller than the fluid passage for one or both of the inlet to and/or the outlet from the interior chamber. Fluid entering the pulsation control device reacts with fluid contained within the volume thereof on both sides of the baffle. The baffle attenuates pressure pulses within fluid passing through the interior chamber in response to operation of the reciprocating pump. The pressure drop device dampens high frequency pulsation magnitudes of pressure pulses within fluid passing through the interior chamber in response to operation of the reciprocating pump.
