Stripe Hog Systems
flow of lube water to the packing seals in the UHP
pump. Therefore it is normal and recommended
that the filters be checked frequently and changed
whenever the charge water pressure drops below
40 PSI (2.8 Bar.)
Please remember that the filters can be under
pressure. Always make sure the charge pump is
off, the OMSI PTO disengaged and the pressure
has been bled from the system before removing
the filter caps. You should also make sure to
thoroughly flush the filter canisters and charge
water system when the filters are changed and
before activating the UHP pump.
A valve located on the low pressure (charge
water) side of the pump can be opened to flush
the charge water side of the pump if the system
becomes contaminated. This valve is also used to
assist in purging the system after a filter change
or adding anti-freeze in cold weather operations.
A supply of clean fresh water is critical to the
proper operation of a high pressure waterblasting
system. You should only use clean fresh water
from a potable water source, usually a fire hy
-
drant, and make sure to keep supply hoses and
the area around the tank fill valve clean. Never
use water drawn from retention ponds, canals or
other non-potable sources.
Packing Lube Water and Bilge Pump
Lube and cooling water for the plunger packing
is provided by three cooling lines connected to a
manifold in the charge water supply line near the
pump connection. A metering valve for each line
controls the flow of water to the packing. Lube
water is supplied whenever the engine and charge
pump are operating.
The water flow to the packing should be checked
at the beginning of each shift by monitoring the
flow of water from each packing with the PTO en
-
gaged, the charge pump activated and the engine
at idle. There should be a noticeable flow of water
from each packing. If necessary, use the metering
valves to adjust the flow. If no water is flowing
from any of the packing glands, find and correct
the problem before operating the pump. Refer
to the high pressure pump operation manual for
more information on adjusting the packing lube
water.
Packing lube water is drained from the high pres-
sure pump by a bilge pump drain system. The
system is completely automatic and activated
whenever the OMSI Drive PTO switch is ON. A
