3:1 Low Viscosity Fluid Pumps
PRESSURE RELIEF
PROCEDURE
Always perform this procedure when the pump is shut off
and before checking, servicing, installing, cleaning or
repairing any part of this system.
Perform the following procedure:
A. Disconnect the air supply to the pump.
B. Point the dispensing valve away from yourself and
others.
C. Open the dispensing valve into an appropriate container
until the pressure is relieved.
If the above procedure does not relieve the pressure, the
dispensing valve or hose may be restricted. To relieve the
pressure, very slowly loosen the hose end coupling. Then
loosen completely and clear the dispensing valve and/or
hose.
OPERATION
BEFORE USING PUMP
Prior to operation or maintenance a visual inspection shall
be made. Check pump system for leaks, worn or missing
parts.
Any pump that appears to be damaged in any way, is badly
worn or operates abnormally shall be removed from use
until repairs are made. Contact a factory authorized service
center for repairs.
If overpressurizing of the equipment is believed to have
occurred, contact a factory authorized service center for
inspection of the pump.
Annual inspection by a factory authorized service center is
recommended.
USING PUMP
LUBRICATION
An air line filter/regulator/lubricator Is recommended for use
with your Loctite pump to remove harmful dirt and moisture
from your compressor air supply, and to provide automatic air
motor lubrication.
MATERIAL RESTRICTION PREVENTION
Flush the system as required with a compatible solvent to
prevent material buildup when pumping material that dries or
hardens.
The pump was tested in lightweight oil which was left in
to protect the pump from corrosion. Flushing the pump
before connecting it to the system might be desired to
prevent possible contamination of the fluid you are
pumping.
To reduce the risk of injury from splashing or static
sparking when flushing the pump with solvents, always
hold a metal part of the dispensing valve firmly to the side
of a grounded metal pail and operate pump at lowest
possible fluid pressure.
To start pump, turn on the main air supply. Slowly open the
air regulator. Regulate air pressure from 20-40 psig and
throttle to prime pump. Open the dispensing valve to allow
air to be purged from the system. Allow pump to cycle until
fluid without air pockets flows from dispensing valve, then
close dispensing valve.
After pump is primed, adjust air pressure to achieve a
smooth flow of fluid from the dispensing valve. Do not allow
pump to operate when out of material. Pump will accelerate
quickly and run too fast, resulting in costly damage to the
pump.
If the pump accelerates quickly or is running too fast, stop it
immediately. Check the fluid supply and refill it If necessary.
Prime the pump to remove all air from the system, or flush
the pump and relieve pressure.
In a direct supply system, with adequate air pressure sup-
plied to the motor, the pump starts when the gun or dispens-
ing valve is opened and stalls against pressure when it is
closed.
Use the air regulator to control pump speed and fluid pres-
sure. Always use the lowest pressure required to achieve the
desired results. Higher pressures will cause pump packings
to wear prematurely.
MAINTENANCE
To prevent personal injury, perform PRESSURE RELIEF
PROCEDURE before and after operating the pump and
before performing any maintenance.
To prevent personal injury, perform PRESSURE RELIEF
PROCEDURE before and after operating the pump.

SAFETY INSTRUCTIONS
For professional use only. Observe all warnings. Read and
understand all instructions before operating equipment. Extreme
caution should be used when operating this equipment as personal
injury and/or property damage can result from equipment misuse.
This equipment generates very high fluid pressure. Extreme caution
should be used when operating this equipment as material from
dispensing valve or leaks from loose or ruptured components can
inject fluid through the skin and into the body causing serious bodily
injury including possible need for amputation. Adequate protection is
recommended to prevent splashing of material onto the skin or into
the eyes.
IMPORTANT: If any fluid appears to penetrate the skin, get emergen-
cy medical care immediately! Do not treat as a simple cut. Tell
attending physician exactly what fluid was injected.
INSPECTION INSTRUCTIONS
If overpressurizing 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. Contact the factory authorized warranty and service center
nearest you for repair or adjustments other than maintenance
specified in this manual.
Annual inspection by the factory authorized warranty and service
center nearest you is recommended.
A list of factory authorized warranty and service centers is
available upon request.
ALWAYS read and follow the fluid and solvent manufactur-
er’s recommendations regarding the use of protective clothing
and equipment.
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including splashing
into the eyes or onto the skin, always follow this procedure.
Whenever you shut off the pump, when checking or servicing
any part of the system, and when installing, cleaning or
changing any part of the system.
1. Disconnect air to the pump.
2. Point the dispensing valve away from yourself and others.
3. Open the dispensing valve into an appropriate container
until pressure is relieved.
If you suspect that the dispensing valve or hose is completely
clogged or that pressure has not been fully relieved after
following the above procedure, VERY SLOWLY loosen the
hose end coupling to relieve pressure gradually, then loosen
completely. Now clear the valve or hose.
ALWAYS follow the pressure relief procedure after shutting
off the pump, when checking or servicing any part of the
system, and when installing, cleaning or changing any part of
the system.
ALWAYS check equipment for proper operation before each
use, making sure safety devices are in place and operating
properly. DO NOT alter or modify any part of the equipment as
this may cause a malfunction and result In serious bodily injury.
NEVER point the dispensing valve at any part of the body or at
another person.
NEVER try to stop or deflect material from dispensing valve or
leaking connection or component with your hand or body.

Flush the supply lines and hoses with mineral spirits or oil based
solvent and blow dry with air before connecting them to the
system. This is to purge any contaminants such as dirt, moisture, or
metal shavings that could damage the pump or system components.
The pump was tested in lightweight oil which was left in it to
protect the pump from corrosion. Flushing of the pump before
connecting it to the system might be desired to prevent contamina-
tion of the fluid you are pumping.
DAMAGED PUMPS
Any pump that appears to be damaged in any way, is badly worn
or operates abnormally shall be removed from use until repairs are
made. Contact the factory authorized warranty and service center
nearest you for repairs.
INSTALLATION
An air line filter/regulator/lubricator is recommended for use with
your pump to remove harmful dirt and moisture from the com-
pressed air supply, and to provide automatic lubrication to the air
motor.
This pump can develop 2250 PSI working pressure at 160 PSI
maximum incoming air pressure. Be sure that all system equip-
ment and accessories are rated to withstand the maximum
working pressure of this pump. DO NOT exceed the maximum
working pressure of the lowest rated component in the system.
OPERATION
To start the pump, turn on the main air supply, slowly open the air
regulator until the pump runs smoothly. Open the dispensing valve
to allow air to be purged from the system. Allow pump to cycle until
fluid without air pockets flows from dispensing valve, then close
dispensing valve.
In a direct supply system, with adequate air pressure supplied to
the air motor, the pump starts when the dispensing valve is opened
and stalls against pressure when dispensing valve is closed.
Use the air regulator to control pump speed and fluid pressure.
Always use the lowest pressure required to achieve the desired
results. Higher pressures will cause pump packings to wear
prematurely.
If the pump accelerates rapidly or is running too fast, stop it
immediately. Check the fluid supply and refill if necessary. Prime the
pump to remove all air from the system or flush the pump and
relieve pressure.
MAINTENANCE
To reduce the risk of serious bodily injury or property damage,
NEVER exceed the maximum air or fluid working pressure of the
lowest rated system component.
To reduce the risk of serious bodily Injury, ALWAYS follow the
pressure relief procedure warning whenever you stop the pump
and before checking or repairing any part of the system.
