1.16 Operation
The following must be observed during
commissioning and operation.
○Any information within this manual and
the information within the referenced
documents.
○All laws and regulations to be complied
with by the user.
1.17 Emergency stopping of the pump
station
In case of an emergency stop the pump sta-
tion by:
○Switching off the superior machine or
system in which the pump station has
been integrated.
○Actuating the emergency stop switch of
the superior machine.
1.18 Transport, installation, maintenance,
malfunctions, repair, shutdown,
disposal.
○All relevant persons must be informed
of the activity prior to starting any work.
Observe the precautionary operational
measures and work instructions.
○Carry out transport using suitable trans-
port and hoisting equipment on suitable
ways only.
○Maintenance and repair work can be
subject to restrictions in low or high tem-
peratures (e.g. changed flow properties of
the lubricant). Therefore, where possible,
try to carry out maintenance and repair
work at room temperature.
○Prior to performing work, the product
and the machine, into which the product
will be integrated, must be depressur-
ized and secured against unauthorized
activation.
○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
operating range of moving parts, at an
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.
○Work on electrical components must be
carried out by electrical specialists only.
Observe any waiting periods for dis-
charging, if necessary. Carry out works
on electrical components only while the
system is depressurized and use voltage
isolated tools suitable for electrical works
only.
○Carry out electrical connections only ac-
cording to the information in the valid
wiring diagram and taking the relevant

- 14 -
951-171-016
Version 03
EN 1. Safety instructions
regulations and the local connection con-
ditions into account.
○Do not touch cables or electrical compo-
nents with wet or damp hands.
○Fuses must not be bypassed. Replace
defective fuses always by fuses of the
same type.
○Undertake drilling at non-critical, non-
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.
○All components used must be designed
for:
- the maximum operating pressure
- the maximum/ 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 should 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.
1.19 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

Personal injury / material damage due to
falling of raised parts A, B, C, G, H, K Keep unauthorized persons away. No people may remain under suspended loads. Lift parts with suitable and tested 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 only to components with sufficient
load capacity. If no tightening torques are stated, apply tightening torques according to the
screw size characteristics for 8.8 screws.
Personal injury / material damage due to
electric shock because 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 flexible hose lines or spring coils respectively protective conduits.

2. Lubricants
2.1 General information
Lubricants are used specifically for certain
application purposes. In order to fulfil their
tasks, lubricants must fulfil various require-
ments to varying extents. The most impor-
tant requirements for lubricants 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)
○compatibility with as large a number of
materials as possible
○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/
operator of the machine, preferably together
with the lubricant supplier based on the re-
quirement 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 costly downtimes
through damage to your machine/ system
or damage to the centralized lubrication
system.
Only lubricants specified for the
product 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.
Due to the multitude of possible
additives, it is possible that indi-
vidual lubricants, which according
to the manufacturer's data sheets
fulfil the necessary specification,
are not in fact suitable for use in
centralized lubrication systems
(e.g. incompatibility between
synthetic lubricants and materi-
als). In order to avoid this, always
use lubricants tested by SKF.

2.3 Material compatibility
Lubricants must generally be compatible
with the following materials:
○steel, grey iron, brass, copper, aluminium
○NBR, FPM, ABS, PA, PU
2.4 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 the suitability of the lu-
bricant, please replace it prior to re-commis-
sioning and, if necessary, undertake initial
lubrication manually.
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.

Overview Fig. 1
Pump types ZPU 01/ ZPU 02
basically consist of the following main
components
1 Reservoir with stirring paddle
The reservoir contains the lubricant and,
if needed, a sensor for low-level indication
purposes.
While the pump operates, the stirring paddle
rotates to homogenize and vent the lubricant.
The stirring paddle's lower part pushes the
lubricant towards the pump elements thus im-
proving transportability.
2. Pump element
Supplies lubricant into the lubricant feed line.
3. Pump housing
4. Gear
The gear reduces the motor speed to the speed
required for the pump's eccentric shaft.
5. Motor
The motor drives the pump and is connected to
the gear.

Versions
Version E:
Consists of 1 or 2 pump elements that are fitted
directly into the pump housing.
ZPU 01/ ZPU 02 pump versions E are used
mainly for progressive systems with one or two
lubrication circuits.
