摘要：There is provided a fluid side of a high pressure water pump is to be used with a

pump having a power side which has at least one piston and at least one stuffing box. The

fluid side consists of a unitary substantially block shaped fluid end which defines a

generally cylindrical fluid inlet bore, a generally cylindrical fluid outlet bore, and at least

one generally cylindrical working bore. The working bore intersects the fluid inlet bore

and the fluid outlet bore. Within each working bore there is sealably provided a

substantially tubular suction/discharge seat which has a longitudinal axis, a suction end, a

discharge end, an outside surface extending between the suction end and the discharge

end, and an inside surface extending between the suction end and the discharge end. The

suction/discharge seat defines a plurality of fluid holes at the suction end which provide a

flow path of a fluid from the fluid inlet bore to the inlet end of the fluid end. There is

provided a suction valve linearly movable within the working bore and positioned near an

inlet end of the working bore. Also provided is a discharge valve linearly movable within

the working bore. An end plug is removably positioned in an outlet end of the working

bore. A suction valve stop is positioned between the suction valve and the inlet end of

the working bore and a discharge valve stop is positioned in the working bore between

the discharge valve and the end plug. An insertion/removal tool may be used to

insert/remove all components from the at least one working bore in a single step.
