Replaceable wear inserts of a material resisting abrasive wear due to particulates within pumped fluid are used for the inlet and/or outlet of a pulsation dampener coupled to the outlet of a land-base or mobile-mounted pump. The wear inserts may be integrated with pressure orifice devices contributing to pressure pulsation dampening. The wear inserts may have internal passages or be mounted to create turbulent flow through the pulsation dampener to mitigate the risk of dead spots accumulating particulates. The wear inserts may be sized for either “loose” or “tight” fit within the inlet and outlet to facilitate removability despite the potential for particulates embedding within the gap. Grooves may be provided with O rings to seal against pressure leaks.
