load bearing parts only. Use any available
boreholes. Do not damage lines and ca-
bles when drilling
○Observe possible abrasion points. Protect
the parts accordingly
○Ensure through suitable measures that
movable or detached parts are immobi-
lized during the work and that no limbs
can be caught in between by inadvertent
movements
○Assemble the product only outside of the

adequate distance from sources of heat
or cold. Other units of the machine or ve-
hicle must not be damaged or impaired in
their function by the installation
○Dry or cover wet, slippery surfaces
accordingly
○Cover hot or cold surfaces accordingly

1. Safety instructions
1.20 Initial commissioning / daily start-up
Ensure that:
○All safety devices are completely available
and functional
○All connections are correctly connected
○All parts are correctly installed
○All warning labels on the product are
present completely, highly visible and
undamaged
○Illegible or missing warning labels are to
be replaced without delay
○All components used must be designed
according to the maximum operating
pressure and the maximum respectively
minimum ambient temperature
○No parts of the centralized lubrication
system may be subjected to torsion,
shear, or bending
○Check all parts prior to their usage for
contamination and clean, if necessary
○Lubricant lines must be primed with
lubricant prior to installation. This makes
the subsequent ventilation of the system
easier
○Observe the specified tightening torques.
When tightening, use a calibrated torque
wrench
○When working with heavy parts use suit-
able lifting tools
○Avoid mixing up or wrong assembly
of dismantled parts. Mark these parts
accordingly
1.21 Cleaning
○Risk of fire and explosion when using
inflammable cleaning agents Only use
non-flammable cleaning agents suitable
for the purpose

falling of raised parts A B C G H K Keep unauthorized persons away No people may remain under suspended loads. Lift parts with adequate lifting devices.
Personal injury/ material damage due to
tilting or falling of the product because of
non-observance of the stated tightening
torques
B C G
Observe the specified tightening torques. Fix the product to components with ad-
equate load-bearing capacities only. If no tightening torques are stated, apply tight-
ening torques according to the screw size characteristics for 8.8 screws.
Personal injury/ material damage due to
electric shock in case of damage to the
connection cable
B C D E F G H
Check the connection cable with regard to damages before the first usage and then at
regular intervals. Do not mount cable to moving parts or friction points. If this cannot
be avoided, use spring coils respectively protective conduits.
Personal injury/ damage to material due
to spilled or leaked lubricant B C D F G H K
Be careful when filling the reservoir and when connecting or disconnecting lubricant
feed lines. Always use suitable hydraulic screw connections and lubrication lines
for the stated pressures. Do not mount lubrication lines to moving parts or friction
points. If this cannot be avoided, use spring coils respectively protective conduits.
Loss of electrical protective function due
to faulty installation of electrical compo-
nents after repair
GAfter replacement of electrical components carry out an electrical safety test accord-
ing to ISO 60204-1.

2. Lubricants
2.1 General information
Lubricants are used specifically for cer-
tain application purposes. In order to fulfil
their tasks, lubricants must fulfil various
requirements.
The most important requirements for lubri-
cants are:
○Reduction of abrasion and wear
○Corrosion protection
○Noise minimisation
○protection against contamination or
penetration of foreign objects
○Cooling (primarily with oils)
○longevity (physical/ chemical stability)
○economic and ecological aspects
2.2 Selection of lubricants
SKF considers lubricants to be an element
of system design. A suitable lubricant is se-
lected already when designing the machine
and forms the basis for the planning of a
centralized lubrication system.
The selection is made by the manufacturer
or operator of the machine, preferably to-
gether with the lubricant supplier based on
the requirement profile defined.
Should you have little or no experience with
the selection of lubricants for centralized lu-
brication systems, please contact SKF.
If required we will be glad to support cus-
tomers to select suitable components for
feeding the selected lubricant and to plan
and design their centralized lubrication
system.
You will avoid possible downtimes through
damage to your machine or system or
damage to the centralized lubrication
system.
2.3 Material compatibility
Lubricants must generally be compatible
with the following materials:
○steel, grey iron, brass, copper, aluminium
○NBR, FPM, ABS, PA, PUR
2.4 Temperature characteristics
The lubricant used must be suitable for the
specific ambient temperature of the product.
The viscosity required for proper operation
of the product must be adhered to and must
not be exceeded in case of low temperatures
nor fall below specification in case of high
temperatures. Specified viscosities, see
chapterTechnical data.

Version 01
EN 2. Lubricants
w
Only lubricants specified for the
product (see chapter Technical
data) may be used. Unsuitable
lubricants may lead to a failure of
the product.
Do not mix lubricants. This may
have unforeseeable effects on
the usability and therefore on the
function of the centralized lubri-
cation system.
When handling lubricants the rel-
evant safety data sheets and haz-
ard designations, if any, on the
packaging have to be observed.
2.5 Ageing of lubricants
After a prolonged downtime of the machine,
the lubricant must be inspected prior to
re-commissioning as to whether it is still
suitable for use due to chemical or physical
ageing. We recommend that you undertake
this inspection already after a machine
downtime of 1 week.
If doubts arise as to a further suitability of
the lubricant, please replace it prior to re-
commissioning and, if necessary, undertake
initial lubrication by hand.
It is possible for lubricants to be tested in the
company's laboratory for their suitability for
being pumped in centralized lubrication sys-
tems (e.g. "bleeding").
Please contact SKF. if you have further ques-
tions regarding lubricants.
You may request an overview of the lubri-
cants tested by SKF.
Due to the multitude of possible
additives, individual lubricants,
which according to the manu-
facturer's data sheets fulfil the
necessary specification, may not,
in fact, be suitable for use in cen-
tralized lubrication systems (e. g.
incompatibility between synthetic
lubricants and materials). In
order to avoid this, always use
lubricants tested by SKF.

3.1 Pumps without follower plate
1 Reservoir
The lubricant is stored in the reservoir. De-
pending on the pump version there are differ-
ent types of reservoirs and reservoir sizes.
1.1 Reservoir lid
Serves as a protection against contamination
of the lubricant.After removing the reservoir
lid the reservoir can be filled from the top with
suitable clean lubricant.
1.2 Reservoir venting device
It provides air for the reservoir while the pump
is operating and lubricant is supplied.
10 Stirring paddle
While the pump operates, the stirring paddle
homogenises and smoothens the lubricant.
The stirring paddle's lower vertical part
pushes the lubricant towards the pump ele-
ments thus improving the suction behaviour
of the pump.

2 Pump housing
The pump housing accommodates the motor,
the electrical connection, the filler fitting, the
pump elements and the control PCB.
3 pump elements
The pump can be equipped with up to 3 pump
elements (see note in the type identification
code).
4 Filler fitting
Serves to fill the pump from the bottom. If the
filler fitting is removed, this port can be used
to connect the external grease return from the
pressure control valves to the pump elements
with corresponding accessories.
5 Electrical connection
Serves to provide the (5.1) power supply
(input) of the pump. Depending on the actual
pump version the electrical connection is
provided as a square plug (bottom left) or as a
bayonet plug (top right).
