Packing Lube Water And Bilge Pump
There are three (3) stuffing boxes, packing seals
and plungers in the Ultra-high pressure pump
that must be continuously lubricated and cooled
to achieve maximum life expectancy. Lubrication
and cooling water for the plungers and packing
seals is provided by lubrication lines connected to
the charge water supply line just below the UHP
pump manifold.
A metering valve on each line controls the flow
of water to the stuffing box. The flow of water to
the stuffing box should be checked at the begin -
ning of each shift and periodically during opera-
tion. This should be done with the transmission
PTO engaged, the charge pump activated and
the engine at idle. There should be a steady flow
of water from the back of each gland nut. Insuf-
ficient water flow to packing glands could cause
the stuffing box to overheat and crack or damage
to the packing seals or the plunger. Packing seals
can also be damaged if the metering valves are
Charge Water Supply Line & Metering Valves
open to wide, allowing excessive water flow to
packing glands. For more information on adjusting
the flow of lubrication and cooling water, refer to
the Jetstream Pump Operation manual.
