Contents 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.

Description
Lincoln Industrial rotary 24 V
electric pump uses a 24 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 10% 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 2.
All five models 85736 5 U.S. gallons
(18 liter), 85737 60 lb (27 liter) 85738 120 lb
(181 kg), 85739 400 lb (181 kg) and 85740
40 lb (18 kg) are similar, with main
difference being length of housing tube.

schematic for pump with controller and
Fig. 2 , page 4, 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 24 V electric pump.
All required parts, tools, and equipment
needed to complete operation of
FlowMaster II rotary driven 24 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 1. 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.

Install pump
Pump was tested in lightweight oil left to
protect pump from corrosion. Flush pump
before connecting to system to prevent
contamination of grease with residual oil.
1 Mount pump securely on drum cover so
that it cannot move or vibrate during
operation. Refer to Fig. 4.
2 Connect material supply line to pump
outlet (55).
3 Install safety unloader (77) in open
outlet port.

4 Install high pressure shut-off valve in
material supply line (required).
5 Refer to Fig. 1 and Fig. 2, page 4, to wire
pump motor and vent valve (if used).
6 Fuse motor as recommended in Table 3.
7 Connect power to motor leads.
DANGER
Prior to connecting electrical wiring, perform
lock out/tag out of system.
Failure to comply will result in death or
serious personal injury.
NOTE
If it is necessary to drill mounting holes into
reservoir cover, refer to fig. 3, page 6,
for hole pattern and dimensions.
NOTE
Connect the red motor lead to the positive
side of the circuit. Motor is polarity sensitive
and will not run if not properly connected.
NOTE
Refer to fig. 1, page 4, if system has a
controller. Refer to fig. 2, page 4, if system
does not have a controller.

Operation Crankcase oil service interval
• Check oil level after every 750 hours of
machine operation, or monthly.
• Change 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 temperatures 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).
Prime pump
1 Remove pump outlet line from
outlet port (55).
2 With pump in full container of
lubricant, energize pump.
3 Purge air from pump.
4 Verify lubricant is flowing evenly
from pump.
5 Stop pump.
6 Attach pump outlet line to outlet
port (55).
Set pump speed
1 Refer to Fig. 5 and remove speed
adjustment hex socket head (3 mm)
cover screw.
2 Adjust screw counter-clockwise to reduce
pump speed.
3 Install speed adjustment hex socket head
(3 mm) cover screw.
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 24 V FlowMaster II pump
is equipped with a built in speed control.
Pump speed is factory set to maximum
setting, but easily changed in field.
Speed adjustment screw is located
under cover screw, 120° away from
power cord.
NOTE
Do not reduce pump speed below 20 r/min.
Speed adjustment screw has no stop and has
total of 30 turns.
Refer to Table 2, page 3, 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
Always install relief valve in pump outlet to
ensure pump pressure remains below
5 000 psi (345 bar). Use only high pressure
components.
Failure to comply may result in serious
personal injury.
