a check valve and plug, should be installed at the highest
point of the header line, i.e., at the end point furthest from
the pump. See Figure 1.
If lubrication points are located on a portion of the

equipment that is moving, the divider valves should be
located to minimize the num ber of connecting hoses that
are required to be moving and flexing. See Figure 2.
Keep the lengths of installed tubing, pipes, and hoses

as short as possible in order to minimize the total line
volume/capacitance. Large line volumes increase the
time neces sary to build up to system operating pressure
when the pump is activated, resulting in a slower system
response time. The system re sponse time delay may
cause lube system fault indications when the allotted time
to achieve lubrication of all lube points (Monitor Time) is
exceeded. Therefore, designing and installing the system
overall configuration to minimize the total line lengths
and size is very important in optimizing the system
performance capabilities and minimizing response time.
See Figures 1 and 2 for examples and diagrams of these
general system configuration guidelines.

GENERAL INSTALLATION GUIDELINES
The positioning and orientation of components rel ative to each
other is essential to ensure the cor rect function and operation
of any centralized lu brication system. Even if the proper
components have been selected, improper positioning may
make it more difficult to purge air out of the total system when
air-bleeding procedures are per formed. Any trapped air left in
the lines or compo nents of the lubrication system will impede
and degrade performance and response time capabili ties.
The basic rules to be followed for proper compo nent placement
are:
Place the pump at the lowest point in the sys tem.

In smaller systems with only one or two lubrica tion zones,

position the master divider valve at the same level as the
pump, or slightly higher.
Place the master divider valve as close to the pump or

header line as possible.
Place the secondary divider valves above the master

divider valve(s), but below the majority of lubrication
points. Ideally, all of the second ary divider valves should
be located above all of the master divider valve(s), but
below all of the lubrication points.
In larger systems with multiple lubrication zones, a header

line may be used. In this case, the header should be
configured to rise up-ward from the pump connection
with a continu ous positive slope. Also, a convenient means
of purging air out of the line, such as a T-con nector with
