General Description
The Lincoln Indu trial rotary Hydraulic Pump i a fully
hydraulically operated grea e pump. Grea e output i
proportional to the hydraulic input flow. The pump i
primarily de igned for centralized lubrication y tem uch
a the Single Line Parallel, Single Line Progre ive and
Two Line y tem . An integrated pump control manifold i
incorporated with the motor to control input flow and
pre ure. A 24 volt DC olenoid valve i al o incorporated
a a method to turn the pump on and off.
The pump i driven by the rotary motion of the hydraulic
motor. Rotary motion i converted to reciprocating motion
through an eccentric crank mechani m. The reciprocating
action cau e the pump cylinder to move up and down. The
pump i a po itive di placement double acting pump a
grea e output occur during both the up and down troke of
the pump.
During the down troke, the pump cylinder i extended into
the grea e. Through the combination of hovel action and
vacuum generated in the pump cylinder chamber, the
grea e i forced into the pump cylinder. Simultaneou ly,
grea e i di charged through the outlet of the pump. The
volume of grea e during intake i twice the amount of
grea e output during one cycle. During the up troke, the
inlet check clo e , and one half of the grea e taken in
during the previou troke i tran ferred through the outlet
check and di charged to the outlet port. Typical output of the
pump i hown on page 4.

recommended to prevent pla hing of material onto the
kin or into the eye .
If any fluid appear to penetrate the kin, get emergency
medical care immediately. Do not treat a a imple cut.
Tell attending phy ical exactly what fluid wa injected.
Inspection
If overpre urizing of the equipment i believed to have
occurred, contact the factory authorized warranty and ervice

Installing the Pump
Typical in tallation i hown only a a guide for electing
and in talling y tem component . Contact your Lincoln
Indu trial repre entative for a i tance in de igning a
y tem to uit your pecific need .
The pump wa te ted in light weight oil which wa left in to
protect the pump from corro ion. Flu h the pump before
connecting it to the y tem to prevent contamination of the
grea e with re idual oil.
The pump ha flow and pre ure control integrated into
the manifold (37). A normally clo ed ON/OFF Solenoid Valve
(35) i al o integrated into the manifold and will tart or
top the pump operation.
1. Mount the pump ecurely on the drum cover o that it
cannot move or vibrate during operation.
2. Attach hydraulic upply line to the Inlet and return line to
the Tank port .
3. Connect material upply line to the pump outlet. Plug
the unu ed outlet on oppo ite ide of the pump.
4. In tall high pre ure hut-off valve in the material upply
line. (Required)
5. Connect 24 VDC power upply to the olenoid valve (35).
See Illu tration #1. U e connector plug (36) upplied

Mount the pump ecurely on the drum cover. Failure to do
o could re ult in per onal injury and equipment damage.
Do not exceed 450 PSIG (32 bar) working hydraulic
pre ure. U e high pre ure component to reduce ri k of
eriou injury including fluid injection and pla hing in the
eye or on the kin. All acce orie connected to the pump
outlet mu t have at lea t 5,000 PSIG (350 bar) minimum
hydraulic pre ure. All acce orie connected to the pump
inlet mu t have at lea t 3,500 PSIG (241 bar) minimum
working pre ure.
Operation
All pump are factory et at 350 PSIG (24 bar) working inlet
hydraulic pre ure with a flow rate of 2.5 GPM (9.5 l/min).
Do not change the settings for the pump until after the
start up procedure.
1. Shut off the material upply line valve.
2. Turn on the hydraulic pre ure.
3. Energize the olenoid On/Off valve.
4. Prime the pump by lowly opening the hut-off lubricant
upply line valve. Make ure that all air ha been
expelled from the pump and even lubricant flow i
achieved.
5. Adju t the pump pre ure and flow to the de ired
application requirement . See Pressure and Flow
Control Valve Adjustment for in truction to adju t
pre ure and flow, Do not exceed pump operating
pre ure of 450 PSIG (32 bar).
6. Alway u e the lowe t pump output pre ure and
hydraulic fluid flow to obtain the de ired re ult . Thi
will reduce the pump wear.
Do not exceed maximum operating temperature of the
hydraulic fluid (200º F/93º C) . Never allow the pump to run dry
of lubricant. A dry pump quickly peed up, creating friction
heat, which can damage the eal . Monitor the upply
lubricant level and refill when nece ary.
Setting the Pump Manifold Pressure and
Flow Controls
The pre ure mu t fir t be adju ted to in ure the de ired flow
etting i achieved.
Pressure Control Valve Adjustment
- Loo en the lock nut on the Pre ure control by turning the
nut COUNTERCLOCKWISE.
- Turn the valve tem COUNTERCLOCKWISE until it no
longer turn . The valve tem will un crew until it reache
the top. It will not come off. Thi i the minimum pre ure
etting, which i about 170 p i (12 bar).
- With the pump talled again t pre ure, turn the Pre ure
Control Valve tem CLOCKWISE until the de ired pre ure
i attained on the manifold Pre ure Gage. (Do not exceed
450 PSI.
- Tighten the lock nut by turning CLOCKWISE.
Flow Control Val e Adjustment
- Loo en the lock nut on the Flow Control Valve by turning the
nut COUNTERCLOCKWISE.
- Adju t the flow by turning the valve tem CLOCKWISE to
reduce the flow and COUNTERCLOCKWISE to increa e it.
The Flow Control Valve can be turned in until the valve i
completely clo ed, and out a maximum of 2 1/2 turn . The
valve tem will not come out when fully open (un crewed)
a there i a top at thi po ition.
- After adju ting the flow to the de ired etting, tighten the
lock nut by turning it CLOCKWISE.
Maintenance and Repair
Relieve pre ure from the pump and upply line before
ervicing or repairing the pump, to reduce the ri k of an
injury from injection, pla hing fluid or moving part .
