1. A high-pressure fluid pulsation dampener apparatus (10a) for use on a suspension fluid flow line (16) to reduce pulsation pressures in a flow path (22) of a suspension fluid, the dampener apparatus comprising:
a dampener housing (12), the dampener housing (12) substantially being an elongated pipe having two ends (14) a first-end (14a) and a second-end (14b), and internally having a non-flow fluid chamber (24) along a length (L) of the dampener housing (12), the dampener housing (12) to be oriented vertically in pressure communication with the fluid flow line (16);
an integral pressure damper canister (50) disposed within the non-flow fluid chamber (24) of the dampener housing (12), the damper canister (50) having a damper piston assembly (70) received in the damper canister (50) in pressure communication with the fluid flow path (22) with the piston assembly (70) having a damper piston (72) disposed to move vertically to compress a gas above and within the damper canister (50) and the damper canister (50) being gas pressure chargeable above the piston to greater than 8000 psig, and adapted to dampen a portion of a pressure change of the suspension fluid in the fluid flow thru-path (22);
a sediment management system (200) to ameliorate sediment accumulation within the dampener housing fluid space (28) by flushing it out a damper canister opening (56); and
these elements and features in combination providing said pressure pulsation dampener apparatus (10) to be connected vertically as an appendage to said suspension fluid flow line (16) to reduce pulsation pressures in the flow path (22).
