Explanation of signal
words for safety
Safety
Read and carefully observe these installation
instructions before installing/operating/
troubleshooting the assembly. The assembly
must be installed, maintained and repaired
exclusively by persons familiar with the
instructions.
Install the assembly only after safety
instructions and this guide have been read
and are completely understood.
Adequate personal protection must be
used to prevent splashing of material on the
skin or in the eyes.
Always disconnect power source (electri-
city, air or hydraulic) from the 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 com-
ponents can inject fluid through the skin and
into the body. If any fluid appears to
penetrate the 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 the stated maximum
working pressure of the pump or of the
lowest rated component in your system.
• Always read and follow the fluid manu-
facturer’s recommendations regarding
fluid compatibility, and the use of protec-
tive 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 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
could lead to death or serious injury if
precautionary measures are ignored.
DANGER
Indicates a dangerous situation that will
lead to death or serious injury if
precautionary measures are ignored.
WARNING*
Do not operate equipment
without reading and fully
understanding safety
warnings and instructions.
Failure to follow warnings and
instructions may result in serious injury.
NOTE*
Do not operate equipment without
wearing personal protective gear.
Wear eye protection. Protective
equipment such as dust mask, nonskid
safety shoes, hard hat, or hearing pro-
tection used for appropriate conditions
will reduce personal injuries.
WARNING*
Do not allow any body part to
be trapped between follower
and barrel.
Body parts can be crushed by follower
as follower lowers into barrel.
Failure to comply may result in death
or serious physical injury.
WARNING*
Do not allow fluid to leak onto
floor when removing follower
from barrel. If spill occurs,
clean any fluid on floor before installing
a new barrel.
Failure to comply may result in
personal injury.
* Indicates change.
WARNING*
Do not use equipment to supply,
transport, or store hazardous
substances and mixtures in accordance
with annex I part - of the CLP
regulation (EG /) or HCS 
CFR . marked with GHS,

) Based on lubricants that are free from entrapped air. Lubricants that are aerated will reduce
output of pump.The  Pump is used as the pumping unit for a Centralized Lubrication
System having a single circuit of SL- or SL- Injectors. It is an air-operated, single-stroke,
spring-return pump that discharges . cu. in. into the circuit for each pump cycle.

To fill reservoir
Use manual filler pump  to fill reser-
voir through the filler fitting in the pump
body. Attach coupler on delivery hose to filler
fitting. Stroke filler pump handle until lubri-
cant weepage is noted at air vent hole in the
reservoir (lower portion of follower must rise
beyond air vent hole to expel entrapped air
from lubricant).
To prime system
Supply lines
After pump reservoir has been filled with
recommended lubricant, remove all plugs in
dead ends of the injector manifolds and
supply lines. Operate pump until lubricant
flows from any plug opening. Close opening
with plug. Continue operating pump until
lubricant flows from another plug opening.
Repeat this procedure until all supply lines
are primed.
Feeder lines
Fill each feed line with lubricant before
connecting tines to outlet of injectors and
bearings. This will prevent having to cycle
each injector for every inch of feeder line
between injector and bearing.
Injectors
Check each individual injector for proper
operation.
NOTE
When filling the reservoir, caution
should be used as extreme pressure can
cause damage to reservoir and follower
assembly.
NOTE
Pump must be installed in a vertical
position.
Operation of the
pump
Lubricant in the  translucent reser-
voir flows into the cavity in the  bush-
ing and plunger assembly.
Compressed air entering the bottom of
the  air cylinder (/" N.P.T. female)
moves the  piston upward. As the
piston moves upward, the plunger is also
moved upward into the bushing. As the
plunger moves upward, it moves the charge
of lubricant from the bushing cavity through
the  outlet check to the outlet of the
pump.
When the air pressure to the  air
cylinder is relieved, the  piston spring
moves the piston and plunger downward. In
its extreme down position, the plunger has
retracted below the bushing port, permitting
lubricant to flow into the bushing cavity.
What to do if:
Pump loses prime. - Check lubricant supply.
System fails to cycle and calculated sys-
tem planning has been followed. -- Lubri-
cant may be leaking by the  Ball Check
or the  Packing in the  Check
and Vent Assembly. Remove these parts and
examine for presence of foreign particles.
Clean, or replace parts if worn or damaged.
Pump fails to operate. - Check air supply.
Failure of Injectors to cycle can be caused by
a leak in the supply line.

Manual control
Opening three-way valve for a minimum of
 seconds permits air to flow to pump
forcing air piston forward and lubricant
through supply line to injectors. When valve
is closed, air exhausts back through valve,
and spring in pump returns air piston,
completing lubrication cycle.

NOTE
In reassembling the  Check and
Extension Assembly, the vent pressure
must be reset. Vent pressure can be
varied by the Adjusting Screw, .
The recommended pressure setting is
 P.S.I.G. minimum to  P.S.I.G. maxi-
mum. An improper setting will affect the
pump efficiency. Assemble  with
non-hardening Loctite or stake threads
after adjusting vent pressure.
Low level cut-off kit no. 
May be used as an alarm or signal
device when lubricant drops below an
acceptable level.

Types of installations
Frequency of lubrication cycle can be
controlled mechanically, electrically or
manually.
Mechanical control
When using mechanical motion of machine
to control lubrication frequency, three-way
valve is engaged by cam, permitting air to
pass through valve to pump, forcing air pis-
ton forward and lubricant through supply
line to injectors. When the valve is disen-
gaged, air exhausts back through valve, and
spring in pump returns air piston, complet-
ing lubrication cycle. Cam dwell on three-
way valve must be arranged for a minimum
of  seconds.
When mechanical motion of machine is
too rapid to be used as a source of control for
frequency of lubrication cycle, a cycle timer
with adjustable settings may be used. See
separate instructions for Cycle Timer .

Electrical control
Electrical control
Electrical time switch opens three-way
solenoid salve, permitting air to flow to pump
forcing air piston forward and lubricant
through supply line to injectors. When valve
closes, air exhausts back through valve, and
spring in pump returns air piston, complet-
ing lubrication cycle. Frequency of cycle can
be set as desired.
Manual control
Opening three-way valve for a minimum of
 seconds permits air to flow to pump
forcing air piston forward and lubricant
through supply line to injectors. When valve
is closed, air exhausts back through valve,
and spring in pump returns air piston, com-
pleting lubrication cycle.
