lubricant is provided to the relevant lubricating point. If a lubri-
cating point is insufficiently lubricated, the bearing may become
damaged or jammed.
1.5 Warranty
The instructions do not contain any information on the warranty.
This can be found in the General Conditions of Sales, which are
available at: www.skf.com/lubrication.
2. Lubricants
2.1 General
The intended use of this product is for the centralized lubrication/lu-
brication of bearings and wear points with lubricants. All physical
limitations of use stipulated in the documentation of the product
such as the owner’s manual, technical drawings and catalogs must
be observed.
More specifically, we call your attention to the fact that substances
and mixtures classified as hazardous by the Annex I part 2-5 of the
CLP regulation (EC 1272/2008), and identified with hazard picto-
grams GHS01-GHS06 and GHS08, can only be used to feed the
SKF centralized lubrication systems, transported or distributed by
these systems after consultation with SKF and obtaining written
permission.
All products manufactured by SKF are not approved for use in
conjunction with gases, liquefied gases, pressurized gases in solu-
tion and fluids with a vapor pressure exceeding normal atmospheric
pressure (1013 mbar) by more than 0,5 bar at their maximum per-
missible temperature.
Should there be a need to use the product to convey media other
than lubricants or hazardous substances, this must be discussed
with SKF first and the company must give express written
permission.
In the opinion of SKF, lubricants constitute a design element that
must be considered when selecting components and designing cen-
tralized lubrication systems. The lubrication properties of the lubri-
cants in question must be considered.
2.2 Selection of lubricants
4

DANGER!
Lubricants can contaminate the ground and watercours-
es. Lubricants must be used and disposed of in compliance with
the rules. Instructions and local regulations must be observed
when handling lubricants.
DANGER!
Centralized lubrication systems must be absolutely leak-
free. Leaking centralized lubrication systems can cause a slip
hazard. When performing installation, maintenance, and repairs
test the centralized lubrication system for leaks. Leaky parts of
the centralized lubrication system or components of the lubrica-
tion equipment have to be sealed immediately.
Leaking centralized lubrication systems or components of the lu-
brication equipment are a source of danger in relation to slip hazard
and the risk of injury. These dangers can cause physical injury to
persons or damage to other material assets.
Refer to safety precautions in the lubricant manufacturer's mate-
rial safety data sheet.
Lubricants are hazardous substance. It is essential to respect any
safety instructions given in the lubricant safety data sheet. You can
ask the manufacturer of the lubricant for the material safety data
sheet.
!If required, SKF can help customers to select suitable
components for the conveyance of the selected lubricant
and to plan and design their centralized lubrication system.
DANGER!
Only lubricants that have been approved by SKF for use
with the product may be used. Unsuitable lubricants can cause
product malfunctions and damage to property.
DANGER!
Different lubricants must not be mixed together. Doing so
can cause damage and require extensive cleaning of the prod-
ucts/centralized lubrication system. To prevent confusion, we
recommend that you attach information indicating the lubricant
to be used on the lubricant reservoir.
While the machinery/bearing manufacturer usually specifies lubri-
cants, it is the owner/operator (or maintenance person) who must
finally select the appropriate lubricant, with the help of the lubricant
supplier. When selecting a lubricant, the type of bearing/wear point,
the stresses and strains to be expected during operation, and antici-
pated ambient conditions must be taken into account. All financial/
economic aspects must also be considered.
If you have further questions, you can contact SKF.
We can test lubricants in our own laboratory to establish their
suitability for conveyance (e.g. 'oil separation' behavior) in centralized
lubrication systems.
You can request an overview of lubricant tests offered by SKF
from our Service Center.
2.3 Approved lubricants
The described product can be operated with lubricants that comply
with the specifications in the technical data.
Note that some lubricants may have properties that lie within the
permitted limit values and yet not be suitable for use in centralized
lubrication systems for other reasons. For example, some synthetic
lubricants are not compatible with elastomers.
2.4 Lubricants and the environment
Note that lubricants are harmful to the environment and flammable;
their transportation, storage, and processing are subject to special
precautionary measures. For specifications on transportation, stor-
age, processing, and dangers to the use and the environment for the
lubricant, refer to the material safety data sheet provided by or
available from the lubricant manufacturer. You can ask the manufac-
turer of the lubricant for the material safety data sheet.

3.2 Function
The function principle of the grease injection system for the lubrica-
tion of conveyor chains is more or less the same for all systems (†
fig. 2).
However some models differ from others by the type of lubrication
points, the number of injection heads, etc.
System GVP-S-034-3D and -3G
The lubrication system is dedicated to the lubrication of the pins and
rollers of a conveyor chain. It has only one injection head but two in-
dependent pick-up systems.
The lubrication system is controlled by an AEP3 type control unit.

cation system, see the relevant documentation. If you do
not have access to this documentation, you can request it direct-
ly from SKF.
DANGER!
All installation, setting, maintenance and repair works on
the lubrication system must be carried out only when the con-
veyor is off duty. Working closed to a running conveyor chain
may cause operator's injuries and/or important material
damages.
4.1 Positioning and installation
The lubrication system must be protected from moisture and vibra-
tions but on the other hand mounted so that it is easily accessible to
ensure that all further installation work can be carried out without
difficulty. Ensure that there is sufficient circulating air to prevent the
system from overheating. For information on the minimal and maxi-
mal operating temperature, see the technical data.
The lubrication system is directly installed above the conveyor chain
on an especially adapted rail. It must be fitted to the rail with the two
flanges († pos. A fig. 4). Every flange has two fixing holes for
screws ISO 4762 M10 length 20 mm.

Horizontal adjustment
Horizontal adjustments are made to move the injection head for-
ward or backward in relation to the lubrication point nipple.
• Loosen the four locking screws from the flange († pos. A fig. 9).
There are two screws on each side of the rail.
• Loosen the counter nut († pos. B fig. 9) of the adjustment screw
(† pos. C fig. 9)
• As required, tighten or untighten the adjustment screw to move
the carriage forward or backward.
• When the desired position is reached, tighten the lock nut on the
adjustment screw.
• If you do not need to set the vertical position, tighten the locking
screws. Otherwise leave these screws and go to the next step.
Vertical adjustment
Vertical adjustments are made to move the injection head up or
down in relation to the lubrication point nipple.
• Loosen the 4 locking screws from the flange († pos. A fig. 9) if it
is not already done. There are 2 screws on each side of the rail.
• Loosen the 2 counter nuts († pos. B fig. 9) of the 2 adjustment

4.3 Mechanical adjustments
The position of the lubrication system must be mechanically adjust
to optimize the lubrication process. Several mechanical adjustment
have to be carried out:
• Position adjustment
• Pick-up system adjustment
4.3.1 Position adjustment
With the position setting it is possible to center the injection head of
the lubrication system with the greaser of the lubrication point. The
injection head must be at a distance of 20 mm from the lubrication
point († fig. 8). Therefore it is necessary to set the vertical and
horizontal position of the injection system.
!The position setting must be carried out at the same time
on both sides of the lubrication system. The adjustment of
only one side of the system may cause material damages on the
lubrication system (misalignment).

• Remove the cover of the GVP unit
• Check the GVP unit is on and the air supply open
• Trigger the limit switch († § 6.4). The carriage will then not move
when the different lubrication points are detected.
Pin proximity switch
• Loosen the two counter nuts to bring the switch closer to the pin.
As soon as the pin is detected, the LED on the switch lights on.
• Tighten the two counter nuts.
Roller capacitive proximity switch
• Loosen the two counter nuts to bring the switch closer to the roll-
er. As soon as the roller is detected, the LED on the switch lights
on.
• Tighten the two counter nuts.
Roller inductive proximity switch
• Loosen the two counter nuts to bring the switch closer to the me-
tallic roller. As soon as the roller is detected, the LED on the switch
lights on.
• Tighten the two counter nuts.
• Pull the tab of the limit switch to reset it
• Put back the cover of the GVP unit
6.2.2 Function test of the GVP unit
The functions of the GVP unit are tested from the AEP3 control unit.
The parameters of the different lubrication cycles must be set before
carrying out the tests.
• Make a reset (pause)
• Select the first lubrication cycle (pins).
• Start the lubrication for the first cycle. Check the GVP unit lubri-
cates the pins. You must check the lubrication for at least 10 pins.
• Stop the lubrication of cycle 1.
• Select the second lubrication cycle (plastic rollers).
• Start the lubrication for the second cycle. Check the GVP unit lu-
bricates the plastic rollers. You must check the lubrication for at
least 10 plastic rollers.
• Stop the lubrication of cycle 2.
• Select the third lubrication cycle (metallic rollers).
• Start the lubrication for the third cycle. Check the GVP unit lubri-
cates the metallic rollers. You must check the lubrication for at
least 10 plastic rollers.
• Stop the lubrication of cycle 3.
All three cycle are now in pause. They will restart accordingly the
settings of the AEP3 unit. The GVP lubrication system is now in
service.
!The operating manual of the AEP3 control unit is deliv-
ered with the lubrication system. If you do not have access
to this manual, you can request it from SKF.

6.3 PVP.3 pump
6.3.1 Filling
The lubrication system is equipped with a pneumatic pump and a 8
kg lubricant reservoir. The reservoir is made of transparent plastic
for a visual lubricant level monitoring. It is also equipped with a min.
level switch.
It is important to regularly check the lubricant level and to refill the
reservoir when the level is too low. Fill the reservoir with the quick
release filler coupling († 1 fig. 12).
!The lubricant pressure at the inlet of the PVP.3 pump
must not exceed 3 bar.

6.4 Limit switch
The limit switch is fitted at the end position of the injector carriage
stroke. It is triggered by the carriage when it overruns the autho-
rized stroke end. The pick-up system is pulled away from the lubri-
cation point, the injector is pulled back and the injector carriage
comes back to its initial position. The GVP unit is then in its initial
position.
When the limit switch is triggered, the tab is drawn in
(† 2 fig. 13). Pull the tab out to reset the limit switch.
6.4.1 Manual triggering
It is possible to trigger by hand the limit switch in order to e.g. car-
ry out the setting of the proximity switches. You just to to activate the
wheel († 1 fig. 13) under the limit switch.

6.4 Modification of the injector metered
volume
The GVP lubrication system is delivered with a fixed metered vol-
ume. It is possible to modify later this metered volume. Four differ-
ent metered volumes are available: 0,33 ; 0,5 ; 0,75 or 1 cm3 per
injection.
The metered volume is adjusted by means of reversible metering
stops. They modify the stroke of the metering piston of the injector,
thus the metered volume. Each injector has two reversible metering
stops († fig. 14), one is mounted in the injector, the other delivered
separately. The metered volume is set at the factory at 1 cm3/
injection.
!A number of washers screwed on the injector indicate the
metered volume of the GVP system († fig. 15). There-
fore change the number of washers when modifying the me-
tered volume.
• 1 washer = 0,33 cm3
• 2 washers = 0,5 cm3
• 3 washers = 0,75 cm3
• 4 washers = 1 cm3
The washers are used only to identify the metered volume
and have no impact on it.

The lubrication system GVP must be disconnected from
the power supply and not under pressure when modifying
the metered volume. Therefore turn off the power supply and
depressurize the system.
• Check the GVP unit is off and the air supply closed.
• Loosen the end connector with a wrench (H.19) († 1 fig. 17)
while holding the injector and remove the cylinder from the
injector.
