Fluid end

The medium is fed to the pump through the central suction connection.

From there it flows up the outer surfaces of the high pressure cylinders to the pump head and via the suction valves into the pressurization chamber.

During an upward stroke of a plunger the suction valve closes, the medium is pressurized, the discharge valve opens and the medium discharges via a common central bore at the pump head pressure outlet.
