General description
and information
The Lincoln industrial rotary AC electric
pump uses a AC motor and a two stage
planetary gear drive. Grease output is pro-
portional to the pump revolutions per min-
ute. The pump is primarily designed for cen-
tralized lubrication systems such as the
single line parallel, single line progressive
and two line systems.
The pump is driven by the rotary motion
of the electric motor. Rotary motion is con-
verted to reciprocating motion through an
eccentric crank mechanism. The reciprocat-
ing action causes the pump cylinder to move
up and down. The unit is a positive displace-
ment double-acting pump as grease output
occurs during both the up and down stroke.
During the down stroke, the pump cylin-
der is extended into the grease. Through the
combination of shovel action and vacuum
generated in the pump cylinder chamber,
the grease is forced into the pump cylinder.
Simultaneously, grease is discharged
through the outlet of the pump. The volume
of grease during intake is twice the amount
of grease output during one cycle. During
the upstroke, the inlet check closes, and one
half of the grease taken in during the previ-
ous stroke is transferred through the outlet
check and discharged to the outlet port.
Typical output of the pump is shown in
table 2.
Fig. 1 is the electrical wiring schematic
for the pump with a controller and fig. 2 is

motor.
Inspection
If over pressurizing of the equipment is
believed to have occurred, contact the
factory authorized warranty and service
center nearest you for inspection of the
pump.
Specialized equipment and knowledge is
required for repair of this pump.
Annual inspection by the factory author-
ized warranty and service center nearest
you is recommended.
Damaged Pumps
Do not use any pump that appears to be
damaged, badly worn or operates abnor-
mally. Remove the pump from service and
contact the factory authorized warranty and
service center nearest you for repairs.
A listing of authorized warranty and
service centers is available upon request.
