& Charge Pump
The 40K UHP pump operates at very high pres-
sures and has specific lubrication and maintenance
requirements. Refer to the Lubrication Chart in
this section and the pump manufacturer’s op-
erating and maintenance manual for lubrication
specifications and maintenance schedules.
UHP System Inspection and Maintenance
Daily:
• Check for obvious loose mounting nuts and
bolts.
• Check all hoses, fittings, valves and seals for
leaks and proper operation daily. Repair or
replace leaking or malfunctioning components
before operating the system.
• There are filters in the water system immedi -
ately before the high pressure pump to remove
any particulates from the water prior to en-
tering the UHP pump. These filters should be
changed when dirty or when the charge pump
pressure is 30 PSI (2.1 Bar) or less. The filters
are typically replaced daily.
• Make sure cooling water is flowing to the
plunger packing seals when the charge water
is activated. Constant water flow is essential
to lubricate and cool the seals.
• Make sure the cooling water sump and drain
are clean to provide proper drainage.
• Check for water dripping from UHP Pump weep
holes during high pressure test. Water dripping
from the square holes indicates the face seals
are leaking. Water leaking from round holes in-
dicates the high pressure seals are leaking. Find
and correct the problem before waterblasting.
• Test the dump valve for proper operation daily.
Never operate the system if the dump valve is
not working properly.
• Check the bypass valve and make sure it is
operating properly.
Periodic:
• Service the pump as recommended in the
pump operating manual. Change crankcase
lubricating oil after the first 100 hours and
every 500 hours thereafter.
Important:
Make sure to install the safety plug in crank-
case drain valve when draining is complete.
The safety plug prevents crankcase oil from
draining if the valve is accidentally opened.
• Check pulley clearances and drive belt tension
at least once each month.
• Check and tighten all mounting bolts and
hardware.
• Inspect all hoses and fittings weekly for signs
of deterioration, chaffing and leaks. Repair or
replace as necessary.
