Progressive distributor
WOERNER
In progressive mode based central lubri-
cation systems
The main features of
progressive distributors are as follows
Clear and precise arrangement of
control channels in
Quick fault remedy possible without
having to loosen the pipeline
selectable in accordance with the
lubricant required
due to
refined sliding surfaces
can be replaced during operation
Proportioning volume
per cycle
Lubrication point
connections at max.
Operating pressure at
Throughput volume in case of
Material
Proportioning block
Internal parts
Connecting plate
Delivery medium
Mounting position usually as needed
Note: In case of heavy vibration or
shock load, install the distributor such
that piston axes are situated vertically to
the main direction of shock impact.
An optimum ventilation of the whole
lubrication system is the precondition
for its functionally safe operation.
For quicker ventilation, the flow direc-
tion from bottom to top in the distributor
is of advantage (inlet on bottom side).
The distributor must not be "distorted".
Therefore, when mounting it, always be
careful that the supporting surface is
level.

Monitoring of
progressive distributors
As for instance due to soiling, the flow
through a lubricant point line may be
prevented. This will cause a piston to get
blocked. By virtue of the forced control as
depicted in figures 1 up to 4, the other
pistons will be stopped as well.
Due to this configuration, the proportioning
at all outlets of the distributor can be
monitored by means of a sensor at one
piston only.
Mounting note:
The pistons are provided with an extremely
small fitting clearance. Therefore, the pis-
tons, after the dismantling of a distributor,
must never be interchanged.

Setting of the initiator:
1. Switching on the pump (distributor
circulates).
2. Screwing the initiator completely in. In
the case of a permanent signal, turning
back the initiator as far as an alternating
signal occurs.
3. Turning back the initiator until no signal is
released.
4. Setting the initiator between the limit
values 2 (alternating) and 3 (no
signal)
5. Secure the initiator with a counter nut.

Functional process fig. 1 ... 4:
The lubricant flows from the main line
through the right-side ring groove of piston
III as well as the bypass line (right) and to
the left side of piston I and moves it into its
home position. The lubricant displaced by
piston I is ejected via the left bypass line
through outlet no. 6
After shifting of piston I, lubricant flows to
the left side of piston II and pushes it into its
right-side home position. The displaced
lubricant is ejected via outlet no. 1
After shifting of piston II, lubricant flows to
the left side of piston III and pushes it into its
right-side home position. The displaced
lubricant is ejected via outlet no. 2
After shifting of piston III, lubricant flows to
the right side of piston I and pushes it into its
left-side home position. The displaced
lubricant is ejected via outlet no. 3. The
continuation of that process is evidenced in
the scheme depicted
.
.
.
.
Formula for calculating the lubricant
available per lubrication point:
A progressive distributor allocates the
delivered lubricant to the individual lubri-
cation points in forced order. Due to the
functional process as described herein, a
safe proportioning is ensured
The lubricant delivered to a lubrication
point i can be calculated as follows

Monitoring of
progressive distributors
As for instance due to soiling, the flow
through a lubricant point line may be
prevented. This will cause a piston to get
blocked. By virtue of the forced control as
depicted in figures 1 up to 4, the other
pistons will be stopped as well.
Due to this configuration, the proportioning
at all outlets of the distributor can be
monitored by means of a sensor at one
piston only.
Mounting note:
The pistons are provided with an extremely
small fitting clearance. Therefore, the pis-
tons, after the dismantling of a distributor,
must never be interchanged.

Setting of the initiator:
1. Switching on the pump (distributor
circulates).
2. Screwing the initiator completely in. In
the case of a permanent signal, turning
back the initiator as far as an alternating
signal occurs.
3. Turning back the initiator until no signal is
released.
4. Setting the initiator between the limit
values 2 (alternating) and 3 (no
signal)
5. Secure the initiator with a counter nut.

Combination of outlets,
doubling the proportioning volume at an outlet:
Connect opposing outlets by removing the "Z" screw.
Close any of the outlets by means of a screwed sealing plug
Without removal of the "Z" screw, no outlet must be locked.

Functional process fig. 1 ... 4:
The lubricant flows from the main line
through the right-side ring groove of piston
III as well as the bypass line (right) and to
the left side of piston I and moves it into its
home position. The lubricant displaced by
piston I is ejected via the left bypass line
through outlet no. 6
After shifting of piston I, lubricant flows to
the left side of piston II and pushes it into its
right-side home position. The displaced
lubricant is ejected via outlet no. 1
After shifting of piston II, lubricant flows to
the left side of piston III and pushes it into its
right-side home position. The displaced
lubricant is ejected via outlet no. 2
After shifting of piston III, lubricant flows to
the right side of piston I and pushes it into its
left-side home position. The displaced
lubricant is ejected via outlet no. 3. The
continuation of that process is evidenced in
the scheme depicted

Formula for calculating the lubricant
available per lubrication point:
A progressive distributor allocates the
delivered lubricant to the individual lubri-
cation points in forced order. Due to the
functional process as described herein, a
safe proportioning is ensured
The lubricant delivered to a lubrication
point i can be calculated as follows

The safety and danger information stated in the safety data sheets of the substances used
must be taken into account at all costs.
Transportation of gases, liquefied gases, gases under pressure, vapours and liquids, the

With Directive 2002/95/EC of January 27, 2003, for the limitation of the use of certain
hazardous substances in electrical and electronic devices (RoHS) material bans come into
effect from July 2006 for electrical and electronic devices newly placed on the market for
lead, cadmium, hexavalent chromium, mercury and brominated flame retardants.
In its controls and switching devices, WOERNER only uses materials which fulfil the criteria
of EU Directive 2002/95/EC.
To the extent that hexavalent chromium has been used as corrosion protection in the parts
which we produce ourselves, it has already been replaced by other environmentally
tolerable protective measures.
The mechanical devices supplied by WOERNER are not affected by EU Directive
2002/95/EC.
But as WOERNER is conscious of its responsibility towards the environment, we shall also
use materials fulfilling the requirements of the Directive for devices not covered by EU
Directive 2002/95/EC as soon as they are generally available and their use is technically
possible.
