Water supply problems to the charge pump can be
indicated by low water pressure or by the sound
of the pump. Fluctuating pump RPM, inconsistent
high pitch whines and fluctuating charge water
pressures 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.
NOTICE:
THE UHP PUMP CAN CAvITATE IF THE CHARGE WATER
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.)
Filters
A two stage filter system in the supply line from
the charge pump to the Ultra-High Pressure pump
protects the high pressure pump and system from
debris or contaminants in the water supply.
