Introduction
Introduction
The motor-driven pump units AS are remark-
able in their operational reliability and long
service lives. The lubrication systems are made
in conformity with the generally recognized
rules of technology and the applicable safe
working practices and the rules for accident
prevention. Still hazards may be involved in
their use, which can lead to injury of operators
or other persons or damage the machine or
other property.
To ensure trouble-free operation and prevent
hazard, we kindly ask you to read the pres-
ent manual carefully and observe the notes
contained in it.
The present manual gives the instructions
for operating and servicing standard motor-
driven pump units AS († page 6). In the case
of a special pump unit AS, read carefully the
technical sheet delivered with the pump with
all specic technical data (motor, level switch,
etc...).
Notes on the operating
manual
Text marked with this sign alerts to
special hazards or work that must be
performed with caution.
Keep the operating manual in a safe place so
that it is always available wherever the unit is
in use.
This operating manual is part of the unit, and
it must be given to the operating company
upon sale of the unit.

Safety instructions
Safety instructions
Please comply with the following safety
instructions in order to prevent possible
damage and to ensure that the motor-driven
pump units AS work properly.
Use the motor-driven pump units only in
technically perfect condition for their intended
use. Be aware of hazards and observe the
operating manual.
Especially errors that could affect safety must
be resolved without delay. Safety measures
corresponding to the parameters of the lubri-
cant supplied must be stipulated.
The safety mechanisms must not be damaged,
dismantled, or in any way made inoperable,
nor must they be replaced by parts which have
not been expressly approved of by SKF.
The electrical connection and all interventions
such as repairs, component replacement, etc.
may be carried out only by properly qualied
and instructed personnel.
If units are improperly connected,
substantial material or personal
damage my be the consequence.
Repair work must only be performed after a
trained specialist has disconnected the unit
from power.
Working on systems under electrical
voltage could lead to personal injury.
The dual-line centralized lubrication system
connected to the motor-driven pump unit may
be under pressure. Before extension work,
changes, repairs, etc. it must be depressurized.
Working on systems under pressure
could lead to personal injury.
Unauthorized modications to the
motor-driven pump unit and the
use of unauthorized spare parts and
aids are prohibited and disqualify the
warranty.
Worn-out motor-driven pump units must be
made inoperable and disposed of properly.

Applications
Applications
All products from SKF may be used
only for their intended purpose
as described in this brochure and in
any instructions. If operating instructions
are supplied with the products, they must
be read and followed.
Not all lubricants are suitable for use in
centralized lubrication systems. SKF does
offer an inspection service to test customer
supplied lubricant to determine if it can be
used in a centralized system. SKF lubrica-
tion systems or their components are not
approved for use with gases, liqueed
gases, pressurized gases in solution and
uids with a vapor pressure exceeding
normal atmospheric pressure (1013 mbars)
by more than 0,5 bar at their maximum
permissible temperature.
Hazardous materials of any kind, especially
the materials classied as hazardous by
European Community Directive EC 67/548/
EEC, Article 2, Par. 2, may only be used to
ll SKF centralized lubrication systems and
components and delivered and/or distrib-
uted with the same after consulting with
and receiving written approval from SKF.
The motor-driven pump units AS serve to
supply lubricant to centralized lubrication
systems. Other use or use beyond this purpose
is considered unintended. SKF will not accept
liability for damages resulting from such unin-
tended use.
Only authorized lubricants for the
pump type may be supplied. Unsuit-
able lubricants could lead to the
pump failing and possibly severe properly
damage and personal injury.
Lubricants
The motor-driven pump unit AS can supply
lubricants with the following NLGI grade:
greases up to NLGI grade 2•
A list of authorized lubricants can be found on
the Internet at www.skf.com/lubrication. The
lubricants recommended correspond in their
composition to customary safety regulations,
and they are suitable for use in centralized
lubrication systems.
Whenever using other lubricants, keep in
mind that there are lubricants which, although
within the authorized limits, nevertheless are
unsuitable for dual-line centralized lubrication
systems because of their characteristics.
Keep in mind that lubricants are environ-
mentally unfriendly substances and that their
transport, storage and processing require that
special safety measures be taken.

Design
Figure 1 shows the essential design of the
motor-driven pump unit AS.
The lubricant reservoir is located on the pump
housing. It is equipped with a follower plate in
order to prevent any dust or air penetration
and cavitation. According to the model it has
different level controls (min. level, min. and
max. level). The user rells the reservoir with
the ller coupling on the back side of the pump
housing. This coupling has a lter to ensure the
cleanliness of the lubricant.
The high resistance wheel and worm couple
permit to have a ration of 1/40. The pump
cannot discharge until the drive shaft has car-
ried out a number of revolutions at least equal
to the reduction.
A standard changeover block (†g. 2) is
mounted on the pump housing. It is relatively
compact but it is the core of the AS unit. The
standard changeover block consists of a pump,
changeover valve, lter element and pressure
control valve.
The pump is a double-action piston pump
with one piston and 2 automatically actuated
valves. The changeover valve (1) is activated by
overpressure. It has 2 pilot pistons serving the
main piston, thus avoiding a dead point. The
delivery lter (2) is protecting the system. It is
located on the circuit before the changeover
unit. This ne lter is very easy to remove and
clean up. The pressure regulator (3) makes it
possible to set the pressure in the two lines. In
order to ensure the security of the system, the
pressure regulator can be sealed in order to
avoid any accidental modication.
It is possible to control the good operation of
the changeover unit by means of two differ-
ent control devices: a sight indicator (indicat-
ing rod) of half-cycle or an electric indicator
(switch with LED) of half-cycle .
