The tube lines, hoses, shut-off and way val-
ves, fittings, etc. to be used must be desig-
ned for the maximum operating pressure of
the pump unit, the admissible temperatures,
and the lubricants to be supplied. Further-
more, the lubrication line system must be
secured against inadmissibly high pressure
by means of a pressure relief valve.
All components of the lubrication line sys-
tem, such as tube lines, hoses, shut-off and
way valves, fittings, etc. must be thoroughly
cleaned before assembly. In the lubrication
line system there must not project any seals
towards the inside as these would impede
the lubricant from flowing and contaminati-
on could enter the lubrication line system.
Lubrication lines must be routed in such
way that there won‘t be any air inclusions.
Avoid modifications of the cross-section of
the lubrication line from smaller to larger
diameters in the flow direction of the lubri-
cant. Unavoidable changes in cross-sections
should be done in a smooth manner.
The lubricant flow through the lubrication li-
nes must not be impeded by installing sharp
bends, angle valves, and check valves. Avoid
sudden changes of direction.
To ensure full functioning of the OI-AL-SR
metering devices, these must be primed
with oil immediately after the assembly by
initiating a filling run of at least 200 strokes
per metering device.
Preconditions:
The product/ machine into which the
single-line centralized lubrication system
is integrated is shut down. The single-li-
ne centralized lubrication system is fully
assembled.
• Switch on pump unit and let it run until all
OI-AL-SR metering devices have execu-
ted at least 200 supply strokes
• Switch off pump unit
