Installation Instructions
Appropriate Use
Use the SSVDL lubricant metering devices only for dispensing
lubricants in centralized lubrication systems.
Suitable Lubricants
The progressive metering devices model SSV can be used
for dispensing
- mineral oils of at least 40 mm2/s (cST) or
- greases up to the penetration class NLGI 2
6001a02
IMPORTANT
It must nevertheless be ensured that the
oils or greases used do not alter their con-
sistency significantly in the course of time or
under the influence of temperature or
pressure.
General Safety Instructions
The progressive centralized lubrication system connected
to the Quicklub pump model 203 must always be secured
with a pressure relief valve.
Lincoln SSVDL lubricant metering devices are state of the
art.
Incorrect use may result in bearing damage caused by
poor or over-lubrication.
Every outlet required must be provided with a screw fitting
with a check valve.
Outlets 1 and 2 of the special metering devices model
SSVDL6/5 to 14/13 are connected via a channel (marked
by a double arrow). One of the two outlets must be closed.
This means, the lubricant quantity of the closed outlet is
lead to the opposite outlet (see Fig. 4-9).
1013A94
CAUTION
Damage due to poor lubrication!
If, however, both outlets are connected to a
lube point the bypass metering device
SSVDL6/5 to 14/13 cannot work to 100 %.
The lubricant follows the way of the lowest
resistance. It reaches the lube points of
outlets 1 and 2 only insufficiently or not at
all.
Due to the functional order of its pistons, progressive
metering devices SSVDL6 to 14 will seize if the outlets
positioned directly at the metering device housing are
closed.
- An exception to this rule is the SSVDL metering device,
the outlets 1 and 2 of which are fitted together (see
Fig. 4-9). Here one of the two outlets must be closed.
Modifications or changes to an installed system are not
admissible. Any modification must be subject to prior
consultation with the manufacturer of the lubrication sys-
tem.
Use only original spare parts (see Parts Catalogue)
or the parts approved by SKF.
Installation
Install the metering devices at a suitable location in ac-
cordance with the lubrication diagram.
It is recommended that the metering devices be installed in
such a way that the outlets are not close to the chassis or
the attaching plate. This will facilitate troubleshooting in the
case the system is blocked.
The main metering devices with indicator pin must be
installed in such a way that the indicator pin is easily visible.
Use only the main and feed lines specified by SKF and
adhere to the specified system pressures.
Safety Instructions
1013A94
CAUTION
Danger of injury in the case of serious
corrosion of metering device surfaces:
An increasing corrosion of the surfaces will
cause the balls pressed in to lose their hold.
Under pressure, they may suddenly burst
out and cause injuries.
For applications in corrosive environments,
use metering devices in stainless steel
version only.
Regulations for Prevention of Accidents
To prevent accidents, observe all city, state and federal
safety regulations of the country in which the product will
be used.
Avoid the operation with
- unapproved parts.
- insufficient or contaminated lubricants.
Operation, Repair and Maintenance
Authorized and instructed personnel who are familiar with the
centralized lubrication systems should only perform repair.

Features of a Progressive Metering Device
The term ”progressive” refers to the special features of the
lubricant distribution within the metering devices, e.g.
- the successive movements of the individual pistons
within the metering device due to the supplied lubricant
being under pressure;
- the pistons move in a predetermined order and the cy-
cles are repeated constantly;
- each piston must have completed its movement fully
before the next piston can be moved, no matter whether
the lubricant is dispensed continuously or intermittently;
- the pistons operate interdependently of one another;
- no lubrication point which is connected to the system is
omitted.

Fig. 3-2 Poss ble pump connections
When they are used in connection with hand-operated

Fig. 2-3 Metering and control piston assy.
Function Principle and Reliability
The progressive function sequence results from the inter-
action (see Fig. 4-2…4-8) of each metering and control
piston assy. (see Fig. 4-1) whereby the metering piston
has priority over the control piston.
The softer running of the metering piston is warranted by
several factors:
- Larger piston surface D at constant input pressure P in
the total SSVDL
- Assembly with larger fit-tolerance S
- Continual running surfaces of piston and cylinder
1 - Metering piston
2 - Control piston
P - Input pressure
D - Larger metering piston diameter
d - Smaller control piston diameter
S - Larger fit-tolerance of the metering piston
s - Smaller fit-tolerance of the control piston
L - Continual running surfaces of metering piston and cylinder
l - Interrupted running surfaces of control piston and cylinder

NOTE
To simplify the description we only show th
e
lubricant distribution for outlets 6, 4, 2, 5, 3
and 1. The remaining distribution operation
s
are derived from the logical pumping se-
quence.
Metering screws (DA, DB, DC) are always mounted on the
side with the even outlet numbers. On the side with odd outlet
numbers, closure screws are used only.
The SSVDL has three functional levels. They are visible from
both sides due to three bore rows (see pos. I to III, Fig. 4-1):
I. Control piston level (behind closure plugs)
II. Metering piston level
(medium level behind metering screws)
III. Outlet level
(behind closure screws and connecting screws)

6001a02
IMPORTANT NOTE
For each lube cycle, the output of the me-
tering piston (V1) and the control pis-
ton (V2) is dispensed on one outlet.
The metering piston stroke and the related
output can be adjusted by means of meter-
ing screws of different lengths.
Short metering screws allow for a long
stroke of the metering piston. I.e. with the
shortest metering screw you achieve the
maximum output.
The longest metering screw compresses
the metering piston completely, so that
only the lubricant quantity of the control
piston (0,08 ccm) is dispensed.
This metering has a proper impact on both
of the outlet bores:

NOTE
For the classification of the metering screw
lengths and their metering quantities, see

When the lubricant supply is interrupted
6001a02
IMPORTANT
When the lubricant supply is interrupt-
ed, please observe:
-
-
The pistons come to a halt.
The lubricant is no longer dispensed to
the lubrication point.
When the lubricant is fed again to the metering device, the
cycle begins from the point where it had been interrupted.

then supplies the enclosed lubricant on the right side of
metering piston A to outlet 2 (V1).
Phase 6
When metering piston A reaches its final position on the
right side, lubricant pressure P moves the control piston A
(black arrow) to the right and additionally supplies the en-
closed lubricant on the right side of control piston A to out-
let 2 (V2).
The total output on outlet 2 is the output of metering pis-
ton A and control piston A (V1 + V2).

Cross-porting of outlets, internal
For the lubricant metering devices SSVDL6/5 to 14/13
with an internal cross-porting of outlets 1 and 2 (bypass
metering device), both outlets are connected (see broken-
lined junction channel between outlet 2 and 1).
One outlet of one side of the metering device is closed in
order to be able to use the double lubricant quantity on
the other side.
Outlet V =
V1Phase 5 + V2Phase 6 + V1Phase 11 + V2Phase 12
Thus the cross-porting of outlets results in further meter-
ing possibilities:
From assigning one metering device outlet per lubrication
point to cross-porting all outlets to one lubrication point,
almost all combinations are practicable.
Cross-porting of outlets, external
Opposite outlets 1 and 2 of metering devices SSVDL may
also be cross-ported externally and then be connected to
a lube point with a tee piece.

Monitoring of the Operation
1064b95
Fig. 5-1 Example of a lubrication system
System-dependent monitoring
The main metering device B (fig. 5-1) and the secondary
metering devices are connected by a high-pressure
hose G. This feature automatically causes the linkage of
the progressive system connected downstream of the
pump.
If only one piston does not move in any metering device
or if the metering device can no longer dispense any lub-
ricant via its outlets, this metering device will block itself.
If one of the secondary metering devices is blocked, the
main metering device is also blocked. The whole progres-
sive system installed downstream of the pump stops op-
erating.
The fundamental internal structure of the progressive
metering device guarantees the self-monitoring of the se-
quence within the metering device.
The linkage makes it possible to monitor the operation of
the whole system.

The metering devices are equipped with an indicator
pin 1a on each side. Both of the indicator pins 1a
(fig. 22a) are connected to the control piston 2 and move
back and forth during the lubricant supply.
