water pump is engaged. The charge pressure
gauge on the control panel must be monitored
closely when engaging the charge water pump.
Once engaged, the pressure should rise immedi-
ately above 10 psi (7 BAR) and continue climbing
to the normal operating pressure of approximately
60-70 psi (4 BAR).
Water supply problems to the charge pump are
indicated by low water pressure or by the sound
of the pump. Fluctuating pump RPM, inconsistent
high pitch whines and fluctuating charge water
pressure are indications of a water supply prob-
lem to the charge pump. If the pressure does not
immediately rise and the pump is whining, im-
mediately turn the charge pump off. Make sure
the supply valve is open, check both filters and/or
bleed the air from the system. Operators should
be familiar with the normal sound of the pump
and stop blasting if the sound changes. Find and
correct the problem before water blasting opera-
tions resume.
CAUTION
THE UHP PUMP CAN CAVITATE IF THE CHARGE WATER
PRESSURE DROPS BELOW 25 PSI (2 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 BAR.)
NOTICE:
UHP SYSTEMS ARE EQUIPPED WITH A PRESSURE SAFETY
SWITCH THAT WILL DEACTIVATE THE DUMP VALVE IF
CHARGE WATER PRESSURE DROPS BELOW 30 PSI (2 BAR).
