Ultra-High Pressure Pump
The Ultra-High Pressure pump (UHP) is a positive
displacement pump that requires a constant water
supply from the charge water pump at a minimum
of 30 PSI (2 BAR) to operate properly and prevent
cavitation. The operator must monitor the charge
water pressure closely and immediately shutdown
the water blasting system if the charge water pres-
sure drops below 30 psi (2 BAR) to protect the
charge water pump from running dry and protect
the UHP pump from damage due to overheating
and cavitation.
The high pressure pump is powered by the axillary
engine PTO that is activated by the CLUTCH switch
in the control panel. The HEAD ROTATION switch
activates the solenoid which enables the hydraulic
rotation of the spray bar that is controlled by the
Head Rotation dial. Green LED lights in the con-
sole switches illuminate to indicate the pump and
spray bar hydraulic rotation are activated. When
the system is activated, the DUMP VALVE switch
turns high pressure water to the Hog Head spray
nozzles on or off.
When the high pressure is turned off by the DUMP
VALVE switch, the dump valve located on the UHP
pump is activated to divert the water from the
Hog Head pressure lines to the bypass line and
back to the clean water tank. The dump valve is
a safety feature that enables high pressure wa-
ter supplied to the blast head to be immediately
reduced to less than 100 PSI (7 Bar) at any time
without causing damage to the high pressure lines
and components.
Maximum operating pressure for the UHP pump
of 40,000 PSI (2,758 Bar) @ 6 gallons (23 Li-
ters) per minute is achieved at maximum engine
operation RPM (Typically 2100 RPM). Ultra-high
water pressure is monitored by the High Pressure
analog gauge on the pump and a digital gauge in
the control panel.
