CAUTION
Explanation of signal
words for safety
Safety
Read and carefully observe these installation
instructions before installing, operating or
troubleshooting the assembly. The assembly
must be installed, maintained and repaired
exclusively by persons familiar with the
instructions.
Install the assembly only after safety
instructions and this guide have been read
and are completely understood.
Adequate personal protection must be
used to prevent splashing of material on the
skin or in the eyes.
Always disconnect power source (elec-
tricity, air or hydraulic) from the pump when
it is not being used.
This equipment generates very high
grease pressure. Extreme caution should be
used when operating this equipment as
material leaks from loose or ruptured com-
ponents can inject fluid through the skin and
into the body. If any fluid appears to pene-
trate the skin, seek attention from a doctor
immediately.
Do not treat injury as a simple cut. Tell
attending doctor exactly what type of fluid
was injected.
Any other use not in accordance with
instructions will result in loss of claim for
warranty or liability.
• Do not misuse, over-pressurize, modify
parts, use incompatible chemicals, fluids,
or use worn and/or damaged parts.
• Do not exceed the stated maximum
working pressure of the pump or of the
lowest rated component in your system.
• Always read and follow the fluid manufac-
turer’s recommendations regarding fluid
compatibility, and the use of protective
clothing and equipment.
• Failure to comply may result in personal
injury and/or damage to equipment.
Indicates a hazardous situation which,
if not avoided will result in death or
serious injury.
WARNING
Safety instruction signs indicate specific
safety-related instructions or
procedures.

General description
and information
The Lincoln industrial rotary V AC electric
pump uses a V 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
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 in table 2.
Fig. 1 is the electrical wiring schematic
for the pump with a controller and fig. 2 is
the electrical wiring schematic for the pump
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.
Overview
This manual details the procedure that must
be followed while installing, operating, trou-
bleshooting and repairing the FlowMaster II
rotary driven V AC electric pump.
All required parts, tools, and equipment
needed to complete the operation of the
FlowMaster II rotary driven V AC electric
pump are defined and listed within this
manual.
Review of the parts list and nomenclature
is recommended before starting
disassembly or operation.
Appropriate use
All pump models are exclusively designed to
pump and dispense lubricants using electric
power. The specifications are shown in
table 1 for the pump. The maximum specifi-
cation ratings should not be exceeded.
Any other use not in accordance with
instructions will result in loss of claims for
warranty and liability.

Installing the Pump
1 Refer to figure 4 and connect the
material supply line (80) to the pump
outlet (55).
Fig. 4
2 Install a safety un–loader (77) in the
open outlet port.
3 Install the high pressure shut-off valve
(79) in the material supply line (80).
!Notice
If it is necessary to drill mounting
holes into reservoir cover, refer to fig. 4
for hole pattern and dimensions.
!Notice
Typical installation as shown in
figure 4 is only for selecting and
installing system components. Contact
your Lincoln Industrial representative for
assistance in designing a system to suit
your specific needs.
!Notice
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.
Prior to connecting electrical wiring,
perform lock out/tag out of system.
Failure to comply may result in personal
injury and/or damage to equipment.
DANGER
A high pressure shut-off valve (79) must
be installed to maintain a pressure
below 5,000 psi (344 bar). Failure to
comply may result in serious
personal injury.

Operation
Verify a relief valve is installed in the
pump outlet to insure pump pressure
remains below 5,000 psi (345 bar). Use
only high pressure components. Failure
to comply may result in serious personal
injury.
WARNING
Crankcase oil service interval
• Check the oil level after every 750 hours
of machine operation, or monthly.
• Change the oil after every 2,000 hours of
machine operation or every year.
• Use SAE 10W30 motor oil in all units
used in an ambient temperature of –40 to
150 °F (–40 to 65 °C). For ambient tem-
peratures of –70 to 50 °F (–56 to 10 °C) ,
use Mobil Aero HFA low temperature oil.
• Oil level should be at indicating dot on
dipstick (middle of crankshaft).
• Use 10W30 motor oil 15 oz. (0,44 l).
Priming the pump
1 Remove the pump outlet line from the
outlet port (55).
2 With the pump in a full container of
lubricant, energize the pump.
3 Purge air from the pump.
4 Verify lubricant is flowing evenly from
the pump.
5 Stop the pump.
6 Attach the pump outlet line to the outlet
port (55).
End of procedure
!Notice
Never allow the pump to run dry
of lubricant. A dry pump quickly speeds
up, creating friction heat, which can
damage the seals. Monitor supply
lubricant level and refill when necessary.
Failure to comply may result in damage
to equipment.
Pumps are not equipped with a high
pressure shut off valve. Do not exceed
maximum rated outlet pressure. Failure
to comply may result in personal injury
and/or damage to equipment.
