Filters
A two stage filter system in the supply line be
-
tween the charge pump and high pressure pump
removes any small debris that may accidentally
find its way into the water supply tanks. The first
stage filter is a 10 micron (Nominal) filter to trap
larger particles. The second stage filter is a 1
micron (Absolute) filter to trap smaller particles
that pass through the first filter.
The filters are critical to the proper operation of
the high pressure blasting system and should be
checked frequently and replaced as necessary.
Dirty charge water filters are the number one
reason for low charge water pressure that can
cause the UHP pump to cavitate and reduce the
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.)
Operating with dirty filters can cause:
• Unwanted particles forced through the filter
resulting in premature failure of the parts.
• Cavitation in the UHP pump which will result
in damage to the pump.
• Reduced flow of lube water to the packing seals
which could damage the seals.
Remember that the filters can be under pressure.
Always make sure the charge pump is off, the
transmission PTO and OMSI PTO are disengaged
and the pressure has been bled from the system
before removing the filter caps. You should also
thoroughly flush the filter canisters and charge
water system when the filters are changed and
before activating the Ultra-High Pressure system.
A purge valve located on the low pressure (charge
water) side of the pump can be opened to purge
the system after a filter change or to flush the
charge water side of the pump if the system be-
comes contaminated.
