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.

In a translucent polyamide casing, a red pin
being fixed to the piston shows the piston's
movement.

Electrical check with initiator:
Casing for initiator:
A pin being connected with the piston
attenuates an initiator once per cycle.
Version "D":
Casing material:
Polyamide, translucent
(Piston movement is visible)
for initiators with a
switching distance of:
8 mm
Version "W":
Casing material:
Polyamide, black
for initiators with a
switching distance of:
5 mm
Use initiator with M18x1 thread!
(When using other initiators than those
depicted below, such initiators must be
checked for suitability.)
