2. Lubricants
2.1 General information
Lubricants are selected specifically for the respective
application. The selection is made by the manufacturer or
operator of the machine, preferably together with the lubricant
supplier. Should you have little or no experience with the
selection of lubricants for lubrication systems, please contact us.
We will be pleased to support you in the selection of suitable
lubricants and components for the construction of a lubrication
system optimized for the respective application. Please observe
the following points when selecting/using lubricants. You will
avoid possible downtimes and damages to your machine or the
lubrication system.
2.2 Material compatibility
Lubricants must generally be compatible with the following
materials:
•Plastics: ABS, CR, FPM, NBR, NR, PA, PET, PMMA, POM, PP,
PS, PTFE, PU, PUR
Metal steel, grey iron, brass, copper, aluminium
2.3 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 not be exceeded in case of low
temperatures nor fall below specification in case of high
temperatures. Specified viscosity, see chapter Technical data.
2.4 Ageing of lubricants
Depending on the experience with the lubricant used, it should
be checked at regular intervals to be determined by the
operator whether the lubricant needs to be replaced due to
ageing processes (bleeding). If there is any doubt as to the
further suitability of the lubricant, it must be replaced before
recommissioning. If you have no experience with the lubricant
used, we recommend testing after only one week.
2.5 Avoidance of malfunctions and
hazards
To avoid malfunctions or hazards, please observe the following:
•When handling lubricants, observe the relevant safety data
sheets (SDS) and hazard designations on the packaging, if
any.
•Due to the large number of additives, individual lubricants
which meet the requirements for pumpability specified in the
instructions may not be suitable for use in centralized
lubrication systems.
•Always use SKF lubrication greases, if possible. These are
optimally suited for use in lubrication systems.
•Do not mix lubricants. This may have unforeseeable effects
on the characteristics and on the usability of the lubricant.
•The ignition temperature of the lubricant must lie at least
50 K over the maximum surface temperature of the
components.

The pump ring assembly shown in Figure 2 , is comprised of a
pump ring (3), a pump shaft (4) with two radial pistons (5) and
the flow adjusting disc with elliptical inner contour (6), which is
attached to the holding disc (7).The pump ring (3) houses the
suction grooves and the pressure bores. The pump shaft (4) ,
which also acts as the drive shaft for the next pump ring via the
slotted coupling, is designed as a rotary valve.
The two radial pistons (5) are held together by a spring (9)
and are pressed against the inner elliptical contour of the flow
adjusting disc (6) due to spring force.
3.3 Mode of operation
As the pump shaft rotates, the two radial pistons (5) move apart
due to the spring loading, until the outer dead center is reached.
During this period, the control bore in the pump shaft (8)

13
connects the space between two radial pistons with a lubricant
inlet in the pump ring. This is the suction phase.
As the pump shaft continues to rotate, due to the elliptically
shaped flow adjusting disc (6), the radial pistons move closer
against the spring force, until the inner dead center is reached.
During this period, the control bore (8) in the pump shaft
connects the space between the two radial pistons (5) with a
lubricant outlet (10) in the pump ring. This is the pressure
phase.
The displacement can be varied continuously (after loosening
the screw rod) by adjusting the position of the holding disc
(attached to flow adjusting disc) as per the marking provided on
the pump ring (please refer Figure 3).
The stroke of the two radial pistons remains the same in
every phase variation; it is fully effective or only partially
effective, depending on the setting of the holding disc.
3.4 Pump Ring Assembly
There are three pump ring variants available as shown in
Table 3.

Drive shaft on the pump gear box is coupled to the superior
machine’s drive shaft. Based on the direction of drive rotation
(1) (CW or CCW), user can vary the pump output from MAX to
MIN by adjusting the holding disc (5) position on the pump ring
(4) as per the below steps:
1. Check the direction of drive rotation (1), by looking from the
end as shown in Figure 5
2. Switch off the pump to ensure pump is in standstill state
3. Slightly loosen the dome nuts (2)
4. Adjust the holding disc (5) to the required position on the
direction scale (3) either in CW or CCW side (MIN to MAX) as
per the procedure:
–If the direction of drive rotation (1) is CW, then adjust the
flow only in CW side from MIN to MAX
–If the direction of drive rotation (1) is CCW, then adjust the
flow only in CCW side from MIN to MAX
5. Output setting : After completion of holding disc setting, the
user can fix the grub screw (6) as shown in Figure 5 (near to
MIN marking) to avoid any accidental change of position of
holding disc on the direction scale.
6. After the flow adjustment setting, evenly tighten the dome
nuts (2) by hand before applying the specific torque of 3+/-1
Nm
NOTICE
Direction of rotation
Improper selection of direction of rotation
(CW/CCW) on the drive side (marked on the gear
box) and on the direction scale (CW/CCW) on the
pump ring could create air / oil suction from the
outlet lines, resulting in the malfunctioning of the
pump.
Always follow the correct steps as stated in this
chapter.
The output of the OCL-M pump for oil (reference viscosity
36 mm2/s) for 2 different gear ratios and 3 different piston
diameter options are given in Figure 8 to Figure 12 of chapter
“4.3 Selection of the pump”.
Piston stroke rate Z =
Drive speed [n]
Gear ratio [l]
The maximum operating pressure varies according to the
operating viscosity of the lubricating medium.
Restrictions apply to the permitted operating viscosity at piston
stroke rates > 50 rpm:
NOTE
•The individual pump ring can be set to not less
than 1/3 capacity
•
Any setting between MIN to 0 could lead to no output
condition
•
The unused outlets can be plugged to an extent of 3
ports per pump ring
•
A provision of internal relieving mechanism (refer Fig
2/13) is provided at each pump shaft to relieve the
excessive pressure from the closed ports
•
There is an intentional gap between holding disc and the
adjacent pump rings. So, the holding disc may be slack
with the pump rings when the dome nut is loosened
