Safety
Read and carefully observe installation
instructions before installing, operating or
troubleshooting assembly. Assembly must
be installed, maintained and repaired
exclusively by persons familiar with
instructions.
Install assembly only after safety
instructions have been read and are
completely understood.
• Adequate personal protection must be
used to prevent splashing of material on
skin or in eyes.
• Always disconnect power source
(electricity, air or hydraulic) from pump
when not in use.
• Equipment generates very high grease
pressure. Extreme caution should be used
when operating equipment as material
leaks from loose or ruptured components
can inject fluid through skin and into body.
If fluid appears to penetrate skin, seek
attention from doctor immediately.
• Do not treat injury as 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 stated maximum working
pressure of pump or of lowest rated
component in system.
• Always read and follow fluid
manufacturer’s recommendations
regarding fluid compatibility, and use of
protective clothing and equipment.
• Failure to comply may result in personal
injury and/or damage to equipment.
NOTE
Emphasizes useful hints and
recommendations as well as
information for efficient and
trouble-free operation.

Description
Lincoln Industrial rotary  V
electric pump uses a  V motor and
either a 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.
Pump is driven by rotary motion of
electric motor. Rotary motion is converted to
reciprocating motion through eccentric crank
mechanism. Reciprocating action causes
pump cylinder to move up and down. Unit is
a positive displacement double-acting pump
as grease output occurs during both up and
down stroke. Pump motor employs an
integral speed control capable of reducing
pump speed to % maximum value.
During down stroke, pump cylinder is
extended into grease. Through combination
of shovel action and vacuum generated in
pump cylinder chamber, grease is forced into
pump cylinder. Simultaneously, grease is
discharged through outlet of pump. Volume
of grease during intake is twice amount of
grease output during one cycle.
During upstroke, inlet check closes, and
one half of grease taken in during previous
stroke is transferred through outlet check
and discharged to outlet port. Typical output
of pump is shown in Table .

difference being length of housing tube.
Fig. ,page , is an electrical wiring
schematic for pump without controller.
Inspection
If overpressurizing of equipment is believed
to have occurred, contact factory authorized
warranty and nearest service center for
inspection of pump.
Specialized equipment and knowledge is
required for repair of pump.
Annual inspection by factory authorized
warranty and nearest service center is
recommended.
Damaged pumps
Do not use any pump that appears to be
damaged, badly worn or operating
abnormally. Remove pump from service and
contact factory authorized warranty and
nearest service center for repairs.
Listing of authorized warranty and service
centers is available upon request.
Overview
This manual details the procedure that must
be followed while installing, operating,
troubleshooting and repairing FlowMaster II
rotary driven  V electric pump.
All required parts, tools, and equipment
needed to complete operation of
FlowMaster II rotary driven  V electric
pump are defined and listed within manual.
Review of 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. Specifications for pump are shown in
table . Maximum specification ratings
should not be exceeded.
Any other use not in accordance with
instructions will result in loss of claims for
warranty and liability.
) Motor controller will shut motor off when outside of voltage limits. Test conducted with NLGI  grade grease at   psi ( bar) backpressure.

Install pump
Pump was tested in lightweight oil and was
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 that
it cannot move or vibrate during operation.
Refer to Fig. .
 Connect material supply line to pump

Operation Crankcase oil service interval
• Check oil level after every  hours of
machine operation, or monthly.
• Change oil after every   hours of
machine operation, or every year.
• Use SAE W motor oil in all units used
in an ambient temperature of
– to  °F (– to  °C). Use Mobil
Aero HFA or equivalent low temperature
oil if pump is to be used continuously in
temperatures below  °F ( °C).
• Oil level should be at indicating dot on
dipstick (middle of crankshaft).
• Crankcase capacity:  oz (, l).
Prime pump
 Remove pump outlet line from
outlet pin nut ().
 With pump in full container of
lubricant, start pump.
 Purge air from pump.
 Verify lubricant is flowing evenly
from pump.
 Stop pump.
 Attach pump outlet line to outlet
pin nut ().
Set pump speed
 Refer to Fig.  and remove speed
adjustment hex socket head ( mm)
cover screw.
 Adjust screw counter-clockwise to reduce

DANGER
Do not exceed maximum rated outlet
pressure. Pumps are not equipped with high
pressure shut off valve.
Failure to comply will result in death or
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
Motor used in  V FlowMaster II pump
is equipped with a built in speed control.
Pump speed is factory set to maximum
setting.
Speed adjustment screw is located
under cover screw, ° away from
power cord.
NOTE
Do not reduce pump speed below  r/min.
Speed adjustment screw has no stop and has
total of  turns.
Refer to table , page , for speed
recommendations.
NOTE
Do not change pump settings until after start
up procedure. All pumps are set to run at
full speed.
Failure to comply may result in damage
to pump.
WARNING
Do not operate pump without relief valve
installed. Pressure must remain below
  psi ( bar). Use only high pressure
components.
Failure to comply may result in serious
personal injury.
