2. Lubricants
2.1 General information
Lubricants are selected specifically for the relevant application.
The manufacturer or operator of the machine should ideally
make the selection in consultation with the supplier of the
lubricant. If you have no or little experience in selecting
lubricants for lubrication systems, please contact us. We would
be happy to assist you in selecting suitable lubricants and
components to build a lubrication system optimized for your
particular application. Consider the following points when
selecting/using lubricants. This will spare you potential
downtime and damage to the machine or lubrication system.
2.2 Material compatibility
The lubricants must generally be compatible with the following
materials:
Plastics: ABS, CR, FPM, NBR, NR, PA, PET, PMMA, POM, PP,
PS, PTFE, PU, PUR
Metals: steel, gray cast iron, brass, copper, aluminum
2.3 Temperature properties
The lubricant used must be suitable for the specific ambient
temperature of the product. The viscosity approved for proper
functioning must neither be exceeded at low temperatures nor
fall too low at high temperatures. For the approved viscosity,
2.4 Aging of lubricants
Based on past experience with the lubricant used, checks should
be conducted at regular intervals defined by the operator, to
determine whether the lubricant needs to be replaced due to
aging processes (oil separation). In case of doubt regarding the
continued suitability of the lubricant, it must be replaced before
the system is started up again. If you do not yet have any
experience with the lubricant used, we recommend conducting
a check after just one week.
2.5 Avoidance of faults and hazards
To avoid faults and hazards, please observe the following:
When handling lubricants, observe the relevant safety data
sheet (SDS) and any hazard labeling on the packaging.
Due to the large number of additives, some lubricants that
meet the pumpability requirements specified in the manual
are not suitable for use in centralized lubrication systems.
Whenever possible, always use SKF lubrication greases. They
are ideal for use in lubrication systems.
Do not mix lubricants. This can have unpredictable effects on
the properties and usability of the lubricant.
Use lubricants containing solid lubricants only after technical
consultation with SKF.
50 kelvin above the maximum surface temperature of the
components.
2.6 Solid lubricants
Solid lubricants may only be used after prior consultation with
SKF. When solid lubricants are used in lubrication systems, the
following rules generally apply:
Graphite:
Maximum graphite content 8%
Maximum grain size 25 µm (preferably in lamellar form)
MoS2:
Maximum MoS2 content 5%
Maximum grain size 15 µm
Copper:
Lubricants containing copper are known to lead to coatings
forming on pistons, bore holes, and mating surfaces. This can
result in blockages in the centralized lubrication system.
Calcium carbonat e:
Lubricants containing calcium carbonate are known to lead to
very heavy wear on pistons, bore holes, and mating surfaces.
Calcium hydroxide:
Lubricants containing calcium hydroxide are known to harden
considerably over time, which can lead to failure of the
centralized lubrication system.
PTFE, zinc, and aluminum:
For these solid lubricants, it is not yet possible to define any
limit values for use in lubrication systems on the basis of
existing knowledge and practical experience.

3. Overview, functional
description
3.1 Field of application
The piston detector is used for monitoring the function of
lubricant metering devices. The monitoring of the centralized
lubrication system and possibly the termination of a lubrication
interval can thus take place in connection with an external
control unit or lubrication pump with control circuit board.
Depending on the type of metering device, different designs
exist for the piston detector which are tailored specially to the
respective metering device type and piston stroke. These are
distinguished from one another by their dimensions/clearance
dimensions and by their respective connection threads.
3.2 How it works
The piston detector is a pressure- resistant inductive proximity
switch which is screwed in at the position of the piston plug
screw in the piston bore of the lubricant metering device and
which detects its piston movement without either contact or
wear being involved.
Its switching function is designed as an NO contact. As long as
the piston detector is acted upon by the piston, it will switch its
plus (+) on the output (2/4), while at the same time a yellow
LED lights up to indicate the circuit state.
NOTE
Function monitoring by means of an inductive piston
detector is contingent on adequate processing of the signal
by an external control unit or by a lubrication pump with
control circuit board.
3.3 Control units and pumps
The inductive piston detector is compatible with the following
control units and pumps:

After receipt of the shipment, it must be inspected for any
shipping damage and for completeness according to the
shipping documents. Immediately inform the transport carrier
of any shipping damage. The packaging material must be
preserved until any discrepancies are resolved.
5.2 Return shipment
Before return shipment, all contaminated parts must be
cleaned. If this is not possible or practical, e.g. if it would impede
fault detection in the case of complaints, the medium used must
always be specified. In the case of products contaminated with
hazardous substances as defined by GHS or CLP regulations,
the safety data sheet (SDS) must be sent with the product and
the packaging must be labelled in accordance with GHS/CLP.
There are no restrictions for land, air, or sea transport. The
choice of packaging should be based on the specific product and
the stresses to be expected during transport (e.g., necessary
anti- corrosion measures in the case of shipment by sea). In the
case of wooden packaging, the applicable import regulations
and the IPPC standards must be observed. Required certificates
must be included in the shipping documents. The following
information, as a minimum, must be marked on the packaging
of return shipments.

Marking of return shipments
5.3 Storage
The following conditions apply to storage:
Dry, low- dust, vibration- free, in closed rooms
No corrosive, aggressive substances at the storage location
(e.g., UV rays, ozone)
Protected against animals (insects, rodents)
If possible, keep in the original product packaging
Protected from nearby sources of heat or cold
In the case of large temperature fluctuations or high humidity,
take appropriate measures (e.g., heating) to prevent the
condensation of water
Before usage, check products for damage that may have
occurred during storage. This applies in particular to parts
made of plastic (due to embrittlement).
5.4 Storage temperature range
For parts not filled with lubricant, the permitted storage
temperature is the same as the permitted ambient temperature

CAUTION
Slipping hazard
Centralized lubrication systems must always be
free of leaks. Leaking lubricant is hazardous. It
creates a risk of slipping and injury. Beware of any
lubricant leaking out during assembly, operation,
maintenance, or repair of centralized lubrication
systems. Leaks must be sealed off without delay.
6.1 General information
Only qualified technical personnel may install the products
specified in the instructions.
The product should be protected as much as possible from
humidity, and vibration, and should be installed so that it is
easily accessible.
During assembly, always pay attention to the following:
Check the piston detector for possible transport damage
The IP enclosure rating must be observed
The lubricant metering device in which the piston detector is
to be used must be compatible with it (see Chapter 3.4 )
Dimensions and connection dimensions can be found in the
Technical Data chapter; the altered installation dimensions of
the lubricant metering device caused by the use of a piston
detector must be taken into account here
The piston detector can be attached to either the left or right
side of the lubricant metering device. It is attached to the right
side at the factory. A conversion to left- side attachment by
the customer can be found in the respective documentation of
the lubricant metering device that is used
It should not be attached to the first or last module / piston
(lubricant metering device PSG1 / PSG2)
No active forces may occur on the piston detector
Other units must not be damaged by assembly work
The product must not be installed within range of moving
parts
The product must be installed at a sufficiently large distance
from sources of heat or cold
Maintain safety clearances and comply with statutory
regulations for assembly and accident prevention.
Carefully clean fittings and tubing prior to beginning
installation
It must be ensured that fittings, connections, and connection
elements are leak- free
Ensure cleanliness; components must be installed without
contamination
Do not use any cleaning wipes containing lint.
6.2 Installation or replacement of the
inductive piston detector

NOTE
Applies to lubricant metering devices VP, VPB, VPK, PSG1,
PSG2:
The factory- set installation of the piston detector takes
place on the lubricant metering device. Installation or
conversion of the piston detector to the left side by the
customer requires the respective metering device piston
to be rotated by 180°; the assembly instructions for the
lubricant metering device used must be taken into
account without fail for this purpose!
Applies to lubricant metering devices PSG1, PSG2:
The piston detector should not be installed at the first or
last module of the lubricant metering device.
Applies to lubricant metering devices VSG, VSL:
The metering device must be designed to support a
piston detector (Type NP / NPI).
1.Deactivate the lubrication system and depressurize the
metering device(1).
2.Ensure wherever possible that no contamination caused by
escaping lubricant can take place, e.g. through utilization of a
suitable collection receptacle.
3.Mount the packing ring (2), lightly greased, on the connection
thread of the new piston detector (3) and then set it down
close to hand on a clean storage surface.
The following steps apply only to t he replacement of a
piston detector t hat is already present:
See Fig. 10and Fig. 11(distinctive feature of lubricant metering
devices VSG and VSL)
Disconnect the connection cable (1) and the adapter cable
(2) (if present) of the piston detector (3).
Remove the shielding sleeve (4) (if present).
Disconnect and unscrew the piston detector (3) together
with the adapter (5) (if present) on the lubricant metering
device (6), taking care to ensure while doing so that any
packing ring (7) which may be present does not get left
behind in the lubricant metering device.
Now continue with item 5.
