Fault Possible cause/s Remedy
No pressure generated for the
standard component during up and
down stroke. The pressure in the
hardener component is very high.
1. Standard component pumps do
not receive any material.
2. Burst discs on high pressure
filter defective.
3. The bleeding valve of the stand-
ard component is leaking.
4. The ball valve on the material
inlet is closed.
Ö
Check the material supply.
Ö
Check the burst discs on the high
pressure filter for the standard
component.
Ö
Check bleeding valve of stand-
ard components for function and
leakage.
Ö
Open the ball valve.
When bleeding, the pressure of
the standard component remains
applied.
The pressure of hardening compo-
nent drops.
1. Bleeding valve of standard com-
ponent does not open.
2. Return flow hoses are clogged.
3. The high pressure filter element
is excessively soiled.
Ö
Check the bleeding valve.
Ö
Check return flow hoses for free
flow.
Ö
Clean high pressure filter.
When bleeding, the pressure of
the hardening component remains
applied.
The pressure of standard compo-
nents drops.
1. Bleeding valve of hardening
component does not open.
2. Return flow hoses are clogged.
3. The high pressure filter element
is excessively soiled.
Ö
Check the bleeding valve.
Ö
Check return flow hoses for free
flow.
Ö
Clean high pressure filter.
When spraying the pressure of
the standard component always
increases in comparison to the hard-
ener component.
1. The high pressure filter element
for the standard component
starts to block up.
2. The seals of the hardener com-
ponent pump are leaking.
Ö
Clean the high pressure filter
element or install a coarser
element.
Ö
Repair the hardening component
pump (replace the packing).
When spraying the pressure of
the hardener component always
increases in comparison with the
standard component.
1. The high pressure filter element
for the hardening component
starts to block up.
2. The packings of the standard
component pump are leaking.
Ö
Clean the filter element for the
high pressure pump or install a
coarser element.
Ö
Repair the standard component
pumps (replace the packings).
When spraying not enough pres-
sure or material is transferred to the
spray gun, even though the pres-
sure in the unit is high enough.
1. The filter elements of the high
pressure filters are excessively
soiled.
2. Mixing block, static mixer,
material hose or spray gun are
blocked.
3. The spray gun nozzle is clogged.
4. The viscosity is too high.
Ö
Clean filter elements or replace
with coarser ones.
Ö
Clean or replace mixing block,
static mixer, material hoses ad
spray gun.
Ö
Replace the spraying nozzle in
the spray gun.
Ö
Replace the material heater.
When flushing the standard mixer
with a pressure-relieved unit and
closed ventilation, the one or both
contact pressure gauges indicate
rising pressure.
The check valves in the mixing block
do not work.
Ö
Clean the mixing block.
Ö
Replace defective balls, valve
seats or springs.
The flushing pump does not work
when changing from "SPAY" to
"FLUSH".
1. The flushing pump is defective.
2. The flushing ball valves on the
mixing block do not open.
Ö
Check whether the flushing
pump is operating.
Ö
Check the function of the flush-
ing pump.
Ö
Check the flushing ball valves.
Ö
If necessary disconnect the
flushing hose from the mixing
unit and replace it with a manual
spray gun.
