Maximum allowable output pressure of
this pump is 7500 p.s.i. Be sure that all
system equipment and accessories
are rated to withstand the maximum
working pressure of this pump. Do Not
exceed the maximum working
pressure of the lowest rated
component in the system.

A. With the pump and controller
systems in a rest state, a preset
time interval occurs as determined
by the bearings lubrication
requirements.
B. When the controller times out, a 24
VDC signal will energize SV1,
forcing it to open.
C. As SV1 opens, the resulting
hydraulic fluid pressure closes the
vent valve and flows through the
pressure reducing valve.
D. The pressure reducing valve lowers
hydraulic fluid pressure to the
operating range of the hydraulic

system. This is to purge any
contamination such as dirt, moisture,
or metal shavings that could damage
the pump or system components.
The pump was tested in lightweight oil
which was left in it to protect the pump
from corrosion. Flushing of the pump
before connecting it to the system
might be desired to prevent
contamination of the grease you are
pumping.
SYSTEM OPERATION
This section describes the operation of
the hydraulic pump, the controller and
how they function with other Lincoln
components in the system. See Figure
(2), System Installation Schematic and
Figure (3), Controller Schematic for this
description. The system operates as
follows:
