HIGH PRESSURE WATER PUMPS
MAINTENANCE
FAILURE REASON CORRECTIVE ACTION
Closing the water pressure
line does not drop pressure
to free circulaiton mode.
Hydraulic system starts to
run through the pressure
relief
valve, emitting excessive
heat.
Insufficient hydraulic
pressure in relation to
pumping fluid pressure,
adjusted with water
pressure unloader valve.
Adjust the hydraulic pressure
up as much as necessary to
enable proper operation of water
pressure unloader valve.
Note that the maximum hydraulic
pressure should not be overrun!
If boosting the hydraulic pressure
is not possible, the water unloader
pressure setting should be
dropped.
Defective water pressure
unloader valve (models
with water pressure
unloader valve).
Repair or replace water pressure
unloader valve.
FAILURE REASON CORRECTIVE ACTION
Sealings and water pistons
wear off repeatedly.
Broken filter. Check and replace filter.
Filter missing totally.
Install filter. Always must use filter,
even with clear tap water.
Leakages.
Hydraulic oil leakages.
Check the tightness of component
mating, tighten screws.
Replace sealings of pumps mated
surfaces if necessary.
Check and tighten couplings.
Replace if necessary.
Pumping fluid leakages.
Check the tightness of component
mating, tighten screws.
Replace sealings of pumps mated
surfaces if necessary.
Check and tighten couplings.
Replace if necessary.
Hyraulic oil-pumping fluid
leakage.
If the draining from leakage
detectors exceeds rate of 10
drops per minute, pump’s sealings
should be replaced.
The rule applies to dropping of
hydraulic fluid, pumping fluid and
their commixture.
