Safety
Read and carefully observe instructions
before unpacking and operating assembly.
Assembly must be installed, maintained and
repaired exclusively by persons familiar
with instructions.
• Use adequate protection to prevent
splashing of material on body.
• Equipment generates high grease
pressure. Extreme caution should be used
when operating as material leaks can
inject fluid into body. If fluid penetrates
skin, seek doctor immediately. Do not treat
injury as cut. Tell attending doctor type of
fluid injected.
• Do not misuse, over-pressurize, modify
parts, use incompatible chemicals, fluids,
or use worn and/or damaged parts.
• Always disconnect power source
(electricity, air or hydraulic) from pump
when not in use.
• Always read and follow fluid
manufacturer’s recommendations
regarding fluid compatibility, and use of
protective clothing and equipment.
• Any other use not in accordance with
instructions will result in loss of claim for
warranty or liability.
• Failure to comply may result in personal
injury and/or damage to equipment.
Explanation of signal
words for safety
NOTE
Emphasizes useful hints and
recommendations as well as
information to prevent property damage
and ensure efficient trouble-free
operation.
CAUTION
Indicates a dangerous situation that
may lead to light personal injury if
precautionary measures are ignored.
WARNING
Indicates a dangerous situation that
may lead to death or serious injury if
precautionary measures are ignored.
DANGER
Indicates a dangerous situation that will
lead to death or serious injury if
precautionary measures are ignored.
WARNING*
Do not use equipment to supply,
transport, or store hazardous
substances and mixtures in accordance
with annex I part - of the CLP
regulation (EG /) or HCS
CFR . marked with GHS,
GHS and GHS hazard pictograms
shown:
* Indicates change.

) Test conducted with Alvania NLGI grease at psi ( bar) back pressure.
Description
Lincoln Industrial rotary V electric
pump uses V motor and single or two
stage planetary gear drive. Grease output is
proportional to pump revolutions per
minute. Pump is primarily designed for
centralized lubrication systems such as
single line parallel, single line progressive
and two line systems.
Unit is double-acting pump as grease
output occurs during both up and down
stroke. Pump motor employs integral speed
control capable of reducing pump speed to
% of maximum value.
During down stroke, pump cylinder is
extended into grease. Grease is forced into
pump cylinder and discharged through
outlet of pump. Volume of grease during
intake is double amount of grease output
during one cycle. During upstroke, inlet
check closes, and half of grease taken in
during previous stroke is transferred
through outlet check and discharged to
outlet port.
Inspection
If equipment over pressurizes, contact
nearest service center for inspection.
Specialized equipment and knowledge is
required for repair of pump. Annual
inspection is recommended.
Damaged pumps
Do not use pump that appears to be
damaged, badly worn or operates
abnormally. Remove pump from service and
contact nearest service center for repairs.

DANGER
Prior to connecting electrical wiring,
perform lock out/tag out of system.
Failure to comply may result in death,
severe personal injury and/or damage
to equipment.
NOTE
If necessary to drill mounting holes into
reservoir cover, refer to Fig. ,page
for hole pattern and dimensions.
Fig.
Install pump
Pump was tested in lightweight oil left in to
protect pump from corrosion. Flush pump
before connecting to system to prevent
contamination of grease with residual oil.
Mount pump securely on drum cover so it
cannot move or vibrate during operation.
Refer to Fig. .
Connect material supply line to pump outlet
().
Install safety unloader () in open outlet
port.
Install high pressure shut-off valve in
material supply line (required).
Refer to Fig. , page to wire pump
motor and vent valve (if used).
Fuse motor as recommended in table
(† Electric FlowMaster II pump).
Connect power to motor leads.
) Fuse for A.
WARNING
Always install relief valve in pump outlet
to ensure pressure remains below
psi ( bar). Use only high
pressure components.
Failure to comply may result in
serious personal injury.
NOTE
Never allow pump to run dry of
lubricant. Dry pump quickly speeds up,
creating friction heat that can damage
seals. Monitor supply lubricant level and
refill when necessary.
Failure to comply may result in
damage to equipment.
NOTE
Do not change pump settings until after
start up procedure. Motor used in V
FlowMaster II pump is equipped
with built in speed control, factory set to
maximum setting.
Failure to comply may result in
damage to pump.
NOTE
Do not reduce motor speed below
rpm. Speed adjustment screw has no
stop and total of turns.
Refer to Electric pump performance
specifications, page for speed
recommendations.
DANGER
Do not exceed maximum rated outlet
pressure. Pumps are not equipped with
high pressure shut off valve.
Failure to comply may result in
personal injury and/or damage
to equipment.
Operation
Prime pump
Remove pump outlet line from outlet port
().
With pump in full container of lubricant,
energize pump.
Purge air from pump.
Verify lubricant is flowing evenly
from pump.
Stop pump.
Attach pump outlet line to port ().
Set pump speed
Remove speed adjustment hex socket head
( mm) cover screw († Fig. ).
Adjust screw counter-clockwise to reduce
pump speed.
Install speed adjustment hex socket head (
mm) cover screw.
Crankcase oil service interval
• Check oil level every hours of
operation, or monthly.
• Change oil every hours of operation
or annually.
• Use SAE W motor oil in all units used
in an ambient temperature of
– to °F (– to °C). For ambient
temperatures of – to °F
(– to °C) , use Mobil Aero HFA low
temperature oil.
• Oil level should be at indicating dot on
dipstick (middle of crankshaft).
• Use W motor oil oz (, l).
