2.19. Transport, installation, maintenance, repairs, servicing
• All relevant people, (e.g. operating personnel, superiors) are to be
informed prior to starting the work about its execution. Observe the
company precautionary measures / working instructions.
• If protective and safety equipment must be dismantled, it must be
reassembled immediately after finishing the work, and then checked for
correct function.
• Ensure through suitable measures that movable / loosened parts are
blocked during the work and that no limbs can be trapped through
inadvertent movements.
• Only carry out transport using suitable hoisting equipment.
• If the motor is transported separately (e.g. repairs), this should be lifted by
the transport lugs / eyebolts. Check that the transport lugs / eyebolts are
fixed tightly prior to lifting. Do not lift any other loads on the transport lugs /
eyebolts. Motors may not be transported on the ventilator cover.
• All the parts to be mounted onto the shaft end of the motor are to be
dynamically balanced according to the balancing system. With a direct
coupling, please ensure that the parts align precisely (observe the
manufacturer's guidelines).
• Assemble the pump only outside the working area of moving parts with
sufficiently large distance to sources of heat or cold.
• Dry wet, slippery surfaces.
• Cover hot or cold surfaces accordingly.
• Prior to carrying out the work, de-energize and depressurize the pump and
secure it against unauthorized switch-on. Work on electrical components
must be carried out by electrical specialists only. Observe any waiting
periods for discharging if necessary.
• Carry out electrical connections only according to the information in the
valid wiring diagram and taking the relevant regulations and the local
connection conditions into account.
• Do not touch cables or electrical components with wet or damp hands.
• Maintenance and repair work can be subject to restrictions in low or high
temperatures (e.g. changed flow properties of the lubricant). Therefore, try
to carry out maintenance and repair work at room temperature if possible.
• Carry out all work on electrical components only using voltage insulated
tools.
• Fuses must not be bypassed. Always replace fuses by such of the same
type.

or damaged in function by the installation of the central lubrication system.
• All components used must be designed for:
o maximum operating pressure
o maximum / minimum ambient temperature
o lubricant to be conveyed
o operating / ambient conditions at the location of use
• Parts of the centralized lubrication system must never be subjected to
torsion, shearing or bending.
• Check all parts prior to use for contamination and clean if necessary.
Lubricant lines should be filled with lubricant prior to installation to make
the subsequent ventilation of the system easier.

ATTENTION
Risk of damage to the machine or system
Do not mix lubricants. This may have unforeseeable effects on the usability and
therefore on the function of the centralized lubrication system.
Due to the multitude of possible additives, it is possible that individual lubricants,
which - according to the manufacturer's data sheets - fulfil the necessary
specification, are not in fact suitable for use in central lubrication systems (e.g.
incompatibility between synthetic lubricants and materials). To avoid this, always
use lubricants which have been tested by SKF.
Please contact the Service Department for an overview of lubricants tested by SKF.
3.3. Ageing of lubricants
After a prolonged machine downtime, the lubricant must be inspected prior to
recommissioning as to whether it is still suitable for use due to chemical / 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 lubricant, please
replace it prior to recommissioning and if necessary, undertake initial lubrication
manually.

4. Technical data
4.1. Operating temperature
min.max.
-20 °C +70 °C
Make sure to use a lubricant that suits the actual ambient temperature (e. g.
lubricant for low-temperature applications
)
.
4.2. Operating pressure
Max. 350 bar
All system parts must be designed for the maximum operating pressure. Each
pump element is to be secured against higher pressures using a suitable pressure
limiting valve. If more pump elements are combined, these have to be secured
together against higher pressures by means of a suitable pressure limiting valve.
4.3. Installation position
Vertical, i.e. reservoir at top

4.6. Weight
Empty weight of pump approx. 36 kg
1 pump element + 0,9 kg
4.7. Electrical connection
The electrical connection is carried out in accordance with the general valid
installation prescriptions for electrical systems.
Tolerance voltage ± 5 %
Tolerance frequency ± 2 %
The waveform and mains symmetry must be maintained.
