Ultra-High Pressure Pump
The high pressure pump (UHP) is a positive dis-
placement pump that requires a constant water
supply from the charge water pump at a minimum
of 30 PSI (2.1 Bar) from the charge water system
to operate properly and prevent cavitation. A
pressure sensitive switch located on the hydraulic
manifold near ultra-high pressure pump is a safety
feature that disengages the 40K clutch and shuts
down the pump when the charge pressure drops
below 30 psi. This protects the charge water pump
from running dry and helps protect the ultra-high
pressure pump from damage due to overheating
and cavitation.
The ultra-high pressure pump is powered by the
truck engine thru a power take off (PTO) engaged
by the 40K clutch in the OMSI gearbox. The PTO
is connected to a pulley and Poly Chain Carbon
belt system that drives the pump. It is engaged
by pressing the “40K Clutch” switch on the con-
sole in the cab of the truck. (Refer to the Startup
Procedure in the operation section of this manual).
Maximum operating pressure for the Ultra-high
pressure pump is 40,000 psi (2,758 bar). Pressure
is monitored by the manual high pressure gauge
on the Ultra-high pressure pump manifold and a
digital gauge on the joystick console in the cab of
the truck.
CAUTION
ENGAGING THE 40K CLuTCH AT HIGH ENGINE RPM WILL
INCREASE WEAR ON THE CLuTCH PLATES AND SHORTEN
THE SERvICE LIFE OF THE CLuTCH, DRIvE BELT AND
OTHER uHP PuMP COMPONENTS. FOR MAXIMuM SERvICE
LIFE, ALWAYS REDuCE ENGINE RPM TO IDLE BEFORE
ENGAGING THE 40K CLuTCH.
The pressure switch circuit 5 / 6 controls the
OMSI 40K Clutch. If the charge water pressure
drops below 30 psi for more than 10 seconds the
clutch on the clutch will disengage.
The pressure switch circuit 1 / 2 controls the
spray bar rotation hydraulic coils. If the charge
water pressure drops below 30 psi the spray bars
will stop spinning.
Maximum operating pressure for the UHP pump of
40,000 psi (2,758 Bar) @ 12 gallons (45 Liters)
per minute is achieved at maximum engine RPM.
(Typically 1400 RPM) Water pressure is moni-
tored by the high pressure gauge on the pump
and a digital gauge in the joystick console. High
