The Lincoln Industrial rotary Hydraulic Pump is a fully
hydraulically operated grease pump. Grease output is
proportional to the hydraulic input flow.

The pump is primarily designed for centralized lubrication systems such
as the Single Line Parallel, Single Line Progressive and
Two Line systems. An integrated pump control manifold is
incorporated with the motor to control input flow and
pressure. A 24 volt DC solenoid valve is also incorporated
as a method to turn the pump on and off.

The pump is driven by the rotary motion of the hydraulic
motor. Rotary motion is converted to reciprocating motion
through an eccentric crank mechanism. The reciprocating
action causes the pump cylinder to move up and down. The
pump is a positive displacement double acting pump as
grease output occurs during both the up and down stroke of
the pump.

During the down stroke, the pump cylinder 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 previous stroke is transferred through the outlet
check and discharged to the outlet port. Typical output of the
pump is shown on page 4 of the manual.
