General Description
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.

avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury.
Safety Instructions
This equipment generates very high grease pressure.
Extreme caution should be used when operating this
equipment as material leaks from loose or ruptured
components can inject fluid through the skin and into the
body causing serious bodily injury. Adequate protection is
recommended to prevent splashing of material onto the
skin or into the eyes.
If any fluid appears to penetrate the skin, get emergency
medical care immediately. Do not treat as a simple cut.
Tell attending physical exactly what fluid was injected.
Inspection
If overpressurizing 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. Contact the factory authorized warranty and

Installing the Pump
Typical installation is shown only as a guide for selecting
and installing system components. Contact your Lincoln
Industrial representative for assistance in designing a
system to suit your specific needs.
The pump was tested in light weight oil which was left in to
protect the pump from corrosion. Flush the pump before
connecting it to the system to prevent contamination of the
grease with residual oil.
The pump has flow and pressure controls integrated into
the manifold (37). A normally closed ON/OFF Solenoid Valve
(35) is also integrated into the manifold and will start or
stop the pump operation.
1. Mount the pump securely on the drum cover so that it
cannot move or vibrate during operation.
2. Attach hydraulic supply line to the Inlet and return line to
the Tank ports.
3. Connect material supply line to the pump outlet. Plug
the unused outlet on opposite side of the pump.
4. Install high pressure shut-off valve in the material supply
line. (Required)
5. Connect 24 VDC power supply to the solenoid valve (35).
See Illustration #1. Use connector plug (36) supplied
with the pump.
NOTE: To install the pump Model 85481 as a replacement
pump for 84961 used on Model 84944, use adapter/spacer
p/n 249616 with bolts p/n 50014, included in the pump
package (see illustration #4).

Mount the pump securely on the drum cover. Failure to do
so could result in personal injury and equipment damage.
Do not exceed 450 PSIG (32 bar) working hydraulic
pressure. Use high pressure components to reduce risk of
serious injury including fluid injection and splashing in the
eyes or on the skin. All accessories connected to the pump
outlet must have at least 5,000 PSIG (350 bar) minimum
hydraulic pressure. All accessories connected to the pump
inlet must have at least 3,000 PSIG (200 bar) minimum
working pressure.
Operation
All pumps are factory set at 350 PSIG (24 bar) working inlet
hydraulic pressure 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 supply line valve.
2. Turn on the hydraulic pressure.
3. Energize the solenoid On/Off valve.
4. Prime the pump by slowly opening the shut-off lubricant
supply line valve. Make sure that all air has been
expelled from the pump and even lubricant flow is
achieved.
5. Adjust the pump pressure and flow to the desired
application requirements. See Pressure and Flow
Control Valve Adjustment for instructions to adjust
pressure and flow, Do not exceed pump operating
pressure of 450 PSIG (32 bar).
6. Always use the lowest pump output pressure and
hydraulic fluid flow to obtain the desired results. This
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 speeds up, creating friction
heat, which can damage the seals. Monitor the supply
lubricant level and refill when necessary.
Setting the Pump Manifold Pressure and
Flow Controls
The pressure must first be adjusted to insure the desired flow
setting is achieved.
Pressure Control Valve Adjustment
- Loosen the lock nut on the Pressure control by turning the
nut COUNTERCLOCKWISE.
- Turn the valve stem COUNTERCLOCKWISE until it no
longer turns. The valve stem will unscrew until it reaches
the stop. It will not come off. This is the minimum pressure
setting, which is about 170 psi (12 bar).
- With the pump stalled against pressure, turn the Pressure
Control Valve stem CLOCKWISE until the desired pressure
is attained on the manifold Pressure Gage. (Do not exceed
450 PSI.
- Tighten the lock nut by turning CLOCKWISE.
Flow Control Valve Adjustment
- Loosen the lock nut on the Flow Control Valve by turning the
nut COUNTERCLOCKWISE.
- Adjust the flow by turning the valve stem CLOCKWISE to
reduce the flow and COUNTERCLOCKWISE to increase it.
The Flow Control Valve can be turned in until the valve is
completely closed, and out a maximum of 2 1/2 turns. The
valve stem will not come out when fully open (unscrewed)
as there is a stop at this position.
- After adjusting the flow to the desired setting, tighten the
lock nut by turning it CLOCKWISE.
Maintenance and Repair
Relieve pressure from the pump and supply lines before
servicing or repairing the pump, to reduce the risk of an
injury from injection, splashing fluid or moving parts.
Always use Lincoln Industrial parts for service and repair.

- Torque wrench (3/8 square drive, 0 - 120 in-lb capacity)
- 1/4 nut driver
- Screwdriver (flat blade, 1/8 blade width)
1. Remove the four Socket Head Screws (33) and separate
Manifold from the Hydraulic Motor (42).
2. Remove Pipe Plug (45) and drain the crankcase oil from
the Pump Housing (46).
3. Remove six self-threading Screws (29) and remove the
Housing Cover (30) and the Cover Gasket (31).
4. Remove Retaining Ring (57) and pull the Shovel Plug
