Charge Water System
The water tank provides clean fresh water to the
low pressure charge pump. The charge pump is
hydraulically powered and activated by the Charge
Pump switch in the control panel. It delivers water
to Ultra High Pressure Pump and should maintain
a minimum of 40 PSI (2.8 Bar) on the Charge
Pressure gauge located in the control panel. A
green LED light in the switch illuminates when the
charge pump is activated.
Note:
The UHP pump can cavitate if the charge wa-
ter pressure drops below 25 PSI (1.7 Bar.)
Cavitation can cause severe damage to the
UHP pump and should never be allowed to
occur. You should always monitor the charge
water pressure and never operate the UHP
pump when the charge water pressure drops
below 30 PSI (2.1 Bar.)
The charge pump impeller will be damaged if the
pump is allowed to run dry for more than a few
seconds. Always monitor the water level in the
clean water tank and make sure you have enough
water for the intended shift. Never operate the
charge water pump when the water tank is low
on water and always stop blasting, turn off the
charge pump and disengage the OMSI Drive PTO
immediately when low water or low charge pres-
sure is observed.
Water supply problems to the charge pump can
also be indicated by the sound of the pump. Fluc-
tuating pump RPM, inconsistent high pitch wines,
and fluctuating charge water pressures are indi -
cations of a water supply problem to the charge
pump. You should be familiar with the normal
sound of the pump and stop blasting if the sound
changes. Find and correct the problem before
waterblasting operations resume.
Two filters in the supply line between the charge
pump and high pressure pump remove any small
debris that may accidentally find its way into the
water supply tank. The first filter is a 10 micron
(Nominal) filter to trap larger particles and the
second filter is a 1 micron (Absolute) filter to trap
small 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

Charge Water Filters
Large Filter is 10 Micron (Nominal) Bag Type Filter
Small Filter is 1 Micron (Absolute) Cartridge Type Filter
