• in continuous operation
• to supply, transport, or store hazardous substances and mixtures
in accordance with annex I part - of the CLP regulation (EC
/)
• to feed, forward, or store gases, liquefied gases, pressurized gases
in solution and fluids with a vapor pressure exceeding normal
atmospheric pressure ( mbar) by more than , bar at their
maximum permissible temperature.
• for the supply, transport , stockpiling of oils and greases containing
glycol or polyglycol.These may damage the reservoir.
1.10 Applicable documents
In addition to this manual, the following documents must be
observed by the respective target group:
• Operational instructions and approval rules
• Safety data sheet (MSDS) of the lubricant used

included, if the product is sold or transferred.
WARNING
System pressure
The product is pressurized during operation. The product
must therefore be depressurized before starting assembly,
maintenance, or repair work


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
2. Lubricants
2.1 General
The intended use of this product is for the centralized lubrication/
lubrication 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 - of the
CLP regulation (EC /), and identified with hazard picto-
grams GHS-GHS and GHS, 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 solution
and fluids with a vapor pressure exceeding normal atmospheric
pressure ( mbar) by more than , 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
NOTE
The manufacturer of the bearing or machinery to be lubricated
will specify the lubricant requirements for each point to be lubri-
cated. You must make sure that the required quantity of lubricant
is provided to the relevant lubricating point. If a lubricating point is
insufficiently lubricated, the bearing may become damaged or
jammed.
NOTE
All SKF products must only be used for their intended purpose and
in accordance with the specifications of the installation instructions
for the product in question.
NOTE
You must observe the machinery manufacturer's information on
the lubricants to be used in the machinery.
NOTE
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.
CAUTION
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.


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.
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 avail-
able from the lubricant manufacturer. You can ask the manufacturer
of the lubricant for the material safety data sheet.
2.4 Lubricants and the
environment
Leaking centralized lubrication systems or components of the lubri-
cation equipment are a source of danger in relation to slip hazard
and the risk of injury. These dangers can cause physical injury to per-
sons or damage to other material assets.
Lubricants are hazardous substance. It is essential to respect any
safety instructions given in the lubricant safety data sheet. The prod-
uct safety data sheet for a lubricant can be obtained from the lubri-
cant manufacturer.
CAUTION
Different lubricants must not be mixed together. Doing so
can cause damage and require extensive cleaning of the
products/centralized lubrication system. To prevent confu-
sion, we recommend that you attach information indicating
the lubricant to be used on the lubricant reservoir. CAUTION
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 compo-
nents of the lubrication equipment have to be sealed
immediately.
2.5 Danger relating to lubricants
WARNING
Lubricants can contaminate ground and watercourses.
Lubricants must be used and disposed of in compliance with
the rules. Instructions and local regulations must be
observed when handling lubricants.

3 Design and function
3.1 Construction
The grease injection units type GVP-S--G and GVP-S--D
contain all mechanic, hydraulic, pneumatic and electrical compo-
nents required for the operation of a lubrication system for conveyor
chains.
Units GVP-S--G and GVP-S--D are simple units, as they
lubricate only one side of the conveyor chain.
Main technical specification
• A grease injection system with cylinder and injection head
• One pick-up system
• An inductive proximity switch and a capacitive proximity switch to
detect rollers (plastic and metallic rollers)
• A remote inductive proximity switch to detect pins
• A chain holding system with cylinder
3.2 Version
In general two units are necessary to lubricate chains of an industrial
conveyor. Each unit is located on one chain side. It is important to pay
attention to the GVP unit model in comparison to the chain running
direction.
• The GVP-S--D unit must be located on the chain right side
regarding the running direction.
• The GVP-S--G unit must be located on the chain left side
regarding the running direction.
Running direction is indicated by an arrow on GVP unit.
CAUTION
It is imperative to respect the correct location of the GVP
unit regarding the chain running direction.
The non-respect of the unit location may result in unit’s
destruction, as well as direct damages to the chain due to
unit’s destruction or indirect damages due to lack of
lubrication.

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.
GVP-S-020-1 system
The lubrication system is dedicated to the lubrication of three differ-
ent lubrication points :
• pins
• plastic rollers
• metallic rollers
It features one injection head and one pick-up system for the three
lubrication points. Three proximity switches help to identify the lubri-
cation points. Signals are sent to AEP control units that manages
lubrication cycles.
The unit has a chain holding system. It makes possible to reduce
the side movement of the chain. A photoelectric sensor monitors the
chain pendulum crossing. When the pendulum is detected, the sen-
sor sends a signal to AEP control unit to release the holding system.
The pendulum goes freely in front of the lubrication unit.

A. The GVP unit is in its starting position.
The pick-up system and the injection system
are in their resting position on the carriage.
The proximity switch detects the roller to be
lubricated.
B. Detection of the roller. A signal is sent to
the control unit which triggers an injection
cycle. The pickup system moves forward to
the roller to be lubricated.
C. The pickup finger is in contact with the
roller to be lubricated.
The carriage is now moving exactly in parallel
to the roller. The injection order is sent. The
injection head moves simultaneously forward
onto the roller to be lubricated.
D. Lubrication phase. This phase is the con-
tact time between the injection head and the
lubrication point (user-configured). The car-
riage keeps moving in parallel to the lubrica-
tion point.
E. The injection time has elapsed. The injec-
tion head is pulled away from the lubrication
point. The pick-up system is retracted. There
is no more contact between the GVP unit and
the chain.
F. Return to the initial position. The injection
and pick-up systems go back to their waiting
position, as well as the carriage.

chain may cause operator's injuries and/or important mate-
rial damages.
6.2 Position
6.2.1 Positioning
To determine the position of the GVP unit consider the following
factors.
Position
• Place as clean as possible.
• In case of a location with high degree of pollution, install a protec-
tion cover against dust and others. With a transparent cover it is
possible to visually monitor the unit operation.
• Air circulation must be sufficient to prevent any excessive tem-
perature rise of the unit.
Supply pump
• Lubricant pump must be located as close as possible to GVP unit.

6.4 Mechanical adjustments
The position of the lubrication unit must be mechanically adjusted to
optimize the lubrication process. Several mechanical adjustment
have to be carried out:
• Position adjustment
• Pick-up system adjustment
6.4.1 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  mm from the lubri-
cation point († fig. 8). Therefore it is necessary to set the vertical
and horizontal position of the injection system.
Horizontal adjustment
Horizontal adjustments are made to move the injection head forward
or backward in relation to the lubrication point nipple.
• Loosen the four fastening screws from the flanges (†pos. A fig. ).
• Loosen the counter nut (†pos. B fig. 9) of the adjustment screw
(†pos. C fig. 9).
• Move the GVP forward or backward to the chain with the adjust-
ment screw († pos. C fig. 9).
• When the desired position is reached, tighten the counter 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 four fastening screws from the two flanges
(† pos. A fig. 9) if it is not already done.
• Loosen counter nut († pos. E fig. 9) of the two adjustment screws
(† pos. D fig. 9).
• Tighten or loosen the adjustment screws to move the carriage up
or down as necessary.
• When desired position is reached, tighten counter nut on adjust-
ment screw.
• Tighten the four fastening screws.
