Fluid End

Assembly

The wet end where three plungers draw CO2 in through suction valves and push it out through discharge valves; on a triplex pump this section sees the full discharge pressure and does all the pumping work. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
