Safety
• Read and carefully observe these
installation instructions before installing,
operating or troubleshooting FlowMaster
II rotary driven AC electric pump. Assembly
must be installed, maintained and
repaired exclusively by persons familiar
with instructions.
• Install assembly only after safety
instructions and this guide have been read
and are completely understood.
• All required parts, tools, and equipment
are defined and listed within this manual.
• Review parts list and nomenclature prior
to disassembly or operation.
• 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 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
components can inject fluid through skin
and into body. If any fluid appears to
penetrate 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 stated maximum working
pressure of pump or of lowest rated com-
ponent in system.
• Always read and follow fluid manufactur-
er’s recommendations regarding fluid
compatibility and use of protective cloth-
ing and equipment.
• Failure to comply may result in death or
serious injury.
NOTE

recommendations as well as
information to prevent property damage
and ensure efficient trouble-free
operation.
CAUTION
Indicates a dangerous situation that can
lead to light personal injury if
precautionary measures are ignored.
WARNING
Indicates a dangerous situation that
may lead to death or serious personal
injury if precautionary measures are
ignored.

Description
FlowMaster II rotary AC electric pump uses
an AC motor and 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 pro-
gressive and two line systems.
Pump is driven by rotary motion of elec-
tric motor. Rotary motion is converted to
reciprocating motion through an eccentric
crank mechanism. Reciprocating action
causes pump cylinder to move up and down.
Unit is positive displacement double-acting
pump, as grease output occurs during both
up and down strokes.
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 Pump performance
(†Table 1, page 4).
Refer to Motor wiring diagram (†Fig. 2,
page 5) for pump motor.
NOTE
Pumps are not recommended for airless
spray systems. They should be con-
verted from : to : gear ratio.
Please contact technical services for
component requirement.

Inspection
If over pressurizing of equipment is believed
to have occurred, contact factory authorized
warranty and service center for inspection.
Specialized equipment and knowledge is
required for repair of pump.
Annual inspection by factory authorized
warranty and service center is
recommended.
Damaged pumps
Do not use any pump that appears to be
damaged, badly worn or operates abnor-
mally. Remove pump from service and con-
tact factory authorized warranty and service
center for repairs. A listing of authorized
warranty and service centers is available
upon request.
) Test conducted with Alvania NLGI  at   psi (68 bar) back pressure.
Appropriate use
All pump models are exclusively designed to
pump and dispense lubricants using electric
power. Specifications are shown in Pump
specifications (†Table 2, page 4). Do not
exceed maximum specification ratings.

WARNING
Do not exceed maximum stated
pressure. Install high pressure shut-off
valve (79) to ensure pressure remains
below   psi (344 bar).
Failure to comply may result in death
or serious injury.


NOTE
Never allow pump to run dry of lubri-
cant. Dry pump quickly speeds up, cre-
ating friction heat that can damage
seals. Monitor supply lubricant level and
refill when necessary.
Failure to comply may result in dam-
age to equipment.
WARNING
Do not exceed maximum stated pres-
sure. Install relief valve to ensure pres-
sure remains below   psi (345 bar).
Use only high pressure components.
Failure to comply may result in death
or serious personal injury.
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.
Operation
Prime pump
1 Remove pump outlet line from
outlet port (55) (†Fig. 4, page 7).
2 With pump in a full container of lubri-
cant, 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).
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 (–40 to 65 °C). For ambient
temperatures of – to  °F
(–56 to 10 °C), use Mobil Aero HFA low
temperature oil.
• Oil level should be at indicating dot on dip-
stick (middle of crankshaft).
• Use W motor oil  oz. (0,44 l).
