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 small water 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 boxes should be checked at the
beginning of each shift and periodically during
operation. This should be done with the with the
truck 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.
Insufficient water flow to packing glands could
cause the stuffing boxes to overheat and crack
or damage the packing seals or the plungers. If
Charge Water Supply Line & Metering Valves
the line metering valves are open too wide, water
flow will be excessive, wasting clean water and
reducing blasting time. For more information on
adjusting the flow of the lubrication and cooling
water refer to Jetstream operations manual.
