GENERAL SAFETY REQUIREMENTS
PRESSURE RELIEF PROCEDURE:
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 the air to the pump.
2) Point dispensing valve away from
yourself and others.
3) Open dispensing valve until
pressure is relieved.
WARNING
!
NOTE: THOROUGHLY READ AND UNDERSTAND THIS
MANUAL BEFORE INSTALLING, OPERATING OR
SERVICING THIS EQUIPMENT.
Because this pump can be
incorporated into pressurized
systems, the following safety
precautions should be observed.
Check equipment regularly and repair or replace worn
and damaged parts.
Never alter or modify any parts of this pump, doing so
may cause damage to pump and/or personal injury.
Under no circumstances should the dispensing valve
be aimed at any person at any time. Personal injury
may result.
Release pressures built up in the system before any
service or repair is begun. See the pressure relief
procedure below.
Do not operate this pump above 150 PSI (10.3 BAR) air
inlet pressure .
Always read and follow the fluid manufacturer’s
recommendations regarding the use of protective
eyewear, clothing and respirators.
IMPORTANT
!
WARNING
!
Pump develops 450 PSI
(31 BAR) maximum working
pressure at 150 PSI (10.3 BAR)
maximum inlet air pressure. Be sure that any components
or accessories used in the system are rated to withstand
this pressure. To determine uid outlet pressure, multiply
the ratio of the pump by the air pressure being used.
EX: 3.1 (3:1 ratio) x 100 PSI = 300 PSI uid pressure.
3.1 (3:1 ratio) x 6.9 BAR = 20.6 BAR
uid pressure.
WARNING
DANGER: Not for use with uids
that have a ash point below 100°F
(38°C). Examples: gasoline, alcohol.
Sparking could result in an explosion which could result
in death.
!
In the presence of explosive vapors, take
action to prevent static sparking. Failure to ground the
pump, piping, valves, containers, or other miscellaneous
equipment can result in re or explosion.
WARNING
!
WARNING
Do NOT use with solvents or other
explosive uids. An explosion can
result in the pump when aluminum &
zinc parts come in contact with certain solvents.
!
NOTE
!
Note: Thermal expansion of the uid in a distribution
system can cause an increase in system pressure that
can damage fluid distribution system components.
Pressure relief valve, 3120-019 is recommended.

PRODUCT DESCRIPTION
The Lynx 3:1 pump is designed to deliver a range
of light weight oils including gear oils. The pump’s
2” bung adapter allows installation directly onto
original containers or bulk tanks. The Lynx pump
accepts a variety of different length and types of
extension and/or suction tubes.
A pump’s ability to deliver oil is based on the
pressure (bar/psi) and quantity of air supplied
to the air motor and the amount of material
discharge (back) pressure to be overcome within
the system.

SAFETY
The pump is intended for non-corrosive and•
petroleum based liquids. It may NOT be used
for other purposes or for pumping gasoline, or
other explosive liquids.
Check that all components used are suitable•
for the operating pressure of the system.
Do not use higher pressure than required for•
the satisfactory functioning of the system.
Before work is undertaken on the pump the•
compressed air should be disconnected from
the pump and the whole system should then
be depressurized.
Check all components thoroughly for damage•
and leakage.
Ensure that the compressed air is disconnected•
from the pump and the system is depressurized
when system is not in use (i.e. overnight or
during longer shut down periods) as there is
always a risk of hoses bursting or pipework
leaking etc.
DIMENSIONS GENERAL
The pump is made up of two main parts: A
compressed air operated two way piston air motor
and a double acting liquid pump. The liquid is
sucked into the pump tube via the bottom valve.
When the piston moves upwards liquid is forced
out of the uid outlet. The uid is forced out of the
pump when the piston is moving in both directions.
The relationship between the air piston and the
pump piston determines the ratio of the pump. If
the pump ratio is 3:1 the theoretical uid pressure
will be 3 times to the air pressure, when the pump
stalls out. The air is exhausted from the pump via
a sound attenuator.
INSTALLATION / OPERATION
To achieve long pump life we recommend that1.
lter regulator to be installed prior to the air
inlet of the pump.
Remove the protective packaging from the2.
pump and also the protective plugs.
Fit the 2” pump adaptor rmly on to the 3.
barrel.
Mount the pump into the pump adaptor and4.
lock into position.
Fit and secure the outlet hose.5.
Fit and secure the air inlet hose, slowly6.

slowly build up uid pressure.
Ensure there are no leaks either on the air7.
inlet or at the uid outlet. To obtain maximum
vacuum all connections should be sealed and
tight.
Slowly increase the air pressure to optimum8.
working pressure.
The maximum permitted air pressure is 150 psi, do not
exceed this limit. Service: Before any servicework is
carried out the compressed air must be turned off to the
pump or the air coupling disconnected. The uid outlet
must be depressurized completely. Follow pressure
relief procedure.

SERVICE
For your personal safety ensure the air is1.
disconnected from the pump and the uid
discharge is depressurized before any service
is carried out. Be cautious when repressurizing
the system after any service work is carried
out.
During service procedures it is important to2.
avoid any scratching or any other damage to
gasket or bearings surfaces. Keep tools and
benches clean. Be extremely cautious when
assembling or dismantling V-pack ings and O-
rings. Exchange all worn or damaged parts no
matter how slightly damaged they seem.
Clean and grease all gasket, bearing surfaces3.
including O-rings and gaskets with teon
grease when reassembling pump.
Try to use parafn to clean pump parts. If water 4.
based cleaners are used, wipe parts clean &
dry immediately to avoid corrosion.

TROUBLESHOOTING
MAINTENANCE
Before any service work is carried out the1.
compressed air must be turned off to the pump
or the air coupling disconnected. The uid
outlet must be depressurized completely.
Clean the air lter, remove all pollutants 2.

foreign objects, ensure no pollutants enter
the barrel as these will be pumped into the
system.
When changing the barrel make sure the pump5.
remains clean (Do not put on to oor otherwise
the oil will become polluted).
When depressurizing the system or removing6.
the outlet hose from the pump ensure there
is a container available to drain the excess
uid into.
