Lubrigun Pump
Lubrigun Pumps 50:1
are air operated, double acting pumps with differential
piston.
The pump discharges the material on “up“ and “down“
stroke to the outlet; material intake on “up“ stroke.
The pump transforms the incoming air pressure in a
50-times higher material delivery pressure.
The pump has a shovel-type foot valve. The shovel
supports the intake of the material to be pumped by
mechanical force; recommended application for
pumping chassis grease.
For pumping fluid and flowable lubricants, this pump
type can be optionally equipped with ball-type Foot
Valve No. 61275-E.
The pump tube is equipped with a precisely fitted piston
for appropriate use which is the pumping of lubricants.
The non-adherence of the designated use, for example
pumping of materials not having lubricating properties
may cause premature wear and damage to the bushing
& plunger assembly of the pump tube.
Accessories
depend on specific requirement. Ask for quotation in
case of requirement.
Air pressure regulator required for pump drive. Use 1/4“
(DN6) FRL-Air service unit (Filter, regulator, gauge,

To operate pump the manufacturer/supplier of the
complete system has to supplement the pump by air
and fluid system components being required for the
individual application.
Ask for standard accessories in case of requirement.
3.5.1 Air supply
Air flow
Air lines and components must have an adequate size
(inside dia.) to allow an unrestricted air flow to pump.
They must not cause pressure drop during normal
operation on increase of pump cycles.
For information about air consumption
⇒ Refer to 3.3‘Technical Data’
Air pressure
The minimum air pressure to operate pump is
2,1 bar. The air pressure being required depends on the
individual application.
The max. air pressure permitted to operate the pump
can occasionally be lower than the max. working
pressure of the airmotor. The max. air operating
pressure depends amongst others on the fluid system
components. Always pay attention to the pressure ratio
of the pump which transforms the air pressure in a
50-times higher fluid pressure.
⇒ Refer to 3.3‘Technical Data’
⇒ Refer to specifications of system components.
3.5.2 Pneumatic system components
The working pressure of pneumatic components must
comply with the pressure (primary / secondary air
pressure) applied to the equipment.
The nominal size (I. D.) of air pressure regulator,
FRL-Air service unit, valves, couplings, etc. shall
normally correspond to the size of the inlet to the
airmotor which is 1/4“ (I.D. 6 mm).
Check if components are designed for air flow required
for the appropriate use!
The connecting point of the air supply line shall be
equipped with an air shut-off valve.
For each pump/pump unit following items are required
• One Air pressure regulator with gauge
• One Air connecting hose
of sufficient length
• One Air quick-coupler
If the compressed air is not clean or is not free from
moisture, use
• One Air filter
We recommend to use a FRL-Air service unit
(Filter, regulator, gauge and lubricator).
If the primary air pressure is higher than the max.
working pressure (air) of the pump or the output
pressure resulting from the pump pressure ratio
exceeds the max. permissible fluid pressure of the
equipment, you also need:
• One Air pressure reducer and safety device
Important note: When using pumps/pump units as
mobile equipment, safety devices must be mounted
directly to the pump. Mobile equipment means that the
pump can be used at different places of operation
and/or the connecting point of the air supply to pump is
not fixed.
• Low level device (Pump shut-off device)
should be used for pumps/pump units in automated
applications or when pump is not permanently
monitored by the operator. Shut-off device prevents
‘run-away’ of pump when out of material and avoids
premature wear and/or damage.
Additional pneumatic components being required to
operate pump are not listed and depend on the
individual application.
3.5.3 Material supply line
Take viscosity or NLGI-class of the material to be
pumped and the lengths of the material line into account
when selecting nominal size (I.D.) of supply line and
system components.
All system components have to comply with the
specifications concerning max. working pressure and
the compatibility with the material to be pumped.
Use control valve (gun) with heavy duty nozzle
designed for power operated lubricating devices when
operating pump as lubricator.
We recommend to use LINCOLN control valve no. 740.
3.5.4 Optional pump accessories
General
Install pump securely upright for operation. Use for
example drum cover, and additionally mounting devices
if required.
• One Drum Cover
(for centering pump on top of barrel)
Drum cover for container-Ø (O.D.)
No. 81523-E025 330-370 mm
No. 81523-E050 380-435 mm
No. 81523-E200 570-600 mm
If the dip length of the pump tube must be adjusted to
the height of the container, then attach to drum cover:
One No. 12643-E059 mounting kit.
For pumping non-fluid lubricants, use:
• One Follower plate for grease
Follower plate for container-Ø (I.D.)
No. 83366-E025 310-330 mm
No. 83366-E050 375-400 mm

5. Operation
Assembling, inspection and maintenance works shall be
carried out by skilled, qualified personnel only.
Note
The pump is only one component of a variety of
individual system components used for transfer and
dispensing of materials.
For that reason, the section ‘Operation’ contains only
general information to operate Lubrigun Pumps.
The pump drive (airmotor) shall be connected to air
supply by an air quick coupling which is required to
manually shut off the pump.
See section 3.5for information regarding devices to
control and monitor pump for operation.
Requirement as well as specifications of such devices
depend on the individual application and system.
At least are required by user :
Shut-off valves for compressed air and material.
Air pressure regulator for the pump drive.
⇒ For details, see operating and safety instructions of
manufacturer/supplier of the complete system.
Warning
Prevent static sparking by grounding
pump/equipment.
Do not operate pneumatic pump drive
with combustible gas.
Do not exceed the stated working
pressure of the pump and other system
components.
5.1 Setting-up for operation
After erection of pump and installation of lines and
components for control and operation are completed
• Perform function check
− Pressure limiting and safety device.
Pressure limiting and safety devices are not required if
the primary air pressure as well as the pump output
pressure achieved by the pressure ratio of the pump do
not exceed the max. working pressure of the pump and
system components.
For max. air pressure to pump and pressure ratio of the
pump
⇒ See 3.3‘Technical Data’
Setting of pressure limiting and safety device depends
on the lowest rated component (for air as well as
material) used in the system.
− Air pressure regulator and gauge.
Turning the adjusting knob of the pressure regulator
clockwise increases the secondary air pressure; turning
it counter-clockwise decreases the pressure.
Check regulator and adjust secondary pressure to
‘Zero’ reading.
− Low level shut-off device.
Setting must assure that pump drive stops and pump is
shut off when container is empty before pump is out of
material and ‘run-away’ condition occurs. Re-adjust
setting, if necessary, after the first container is empty.
• Fill and adjust air lubricator.
− Fill reservoir of lubricator with low viscosity, high
quality machine oil SAE 10.
− Later, when pump is operating, set adjustment
to ~ 1 drop of oil per hour.
Remark: For details concerning filling and adjustments
see instructions of the lubricator model used.
5.2Initial operation.
Assembly, inspection and maintenance works shall be
carried out by skilled, qualified personnel only.
Warning
Do not operate pneumatic pump
drive with combustible gas.
Do not exceed the stated working
pressure of the pump and other
system components.
Hands away from lower part of the
pump (material inlet) and all outlets
for the material.
CAUTION Do not operate pump exceeding
120 pump cycles per minute.
Use clean and moisture-free compressed air only to
operate pump. Do not operate with air contaminated
with materials not compatible with NBR seals.
Prior to initial operation
Regarding protecting oil left in the pump tube refer to
note in section ‘Installation’.
On initial operation
− pump drive must operate slowly in order to allow
pump to intake the material and to prime;
− material lines must be filled and all air must be
pushed out.
⇒ See Operating and Safety Instructions of the
manufacturer / supplier of the complete material
dispensing system.
Before operating pump
• If using a follower plate (when pumping non-fluid
materials):
− Follower to be seated onto material without trapped
air beneath follower plate.
• Air pressure for operating pump drive must be set to
‘Zero’ at air pressure regulator.
• Shut-off valve(s) of the material supply line must be
turned to position ‘open’ to allow air to be purged
from the system during the initial filling.
− Assistant persons with collecting can must monitor
the material outlet(s) and close the outlet (quarter-
turn valve, flow gun, etc.) when material flows
without air pockets.
Safety note: Wear safety glasses!

Operation
Initial Operation
Pump Priming
The pump takes in (sucks) the material on up-stroke
and discharges it under pressure to the pump outlet on
up- and down-stroke. As the pump inlet is not yet filled
with material, the pump must cycle slowly in the
beginning in order to prime.
• Couple air connecting hose for pump drive by air
quick-coupling to airmotor.
• Slowly regulate the secondary air pressure (air
pressure operating the airmotor) > ‘Zero’ using the
air pressure regulator.
− When pump drive starts to operate do not increase
air pressure to pump.
If air pressure is too high and pump fails to prime,
immediately reduce air pressure to pump step by
step and allow pump to cycle slowly.
• Allow pump to cycle very slowly until pumping
material fills out pump and lines.
− If pump stalls (because of friction) before all material
lines are filled, cautiously increase air pressure.
• Close outlet of material line when all air is pushed
out and material flows without air pockets.
The pump should stalI against pressure when material
outlet(s) are closed and the system is properly filled with
material.
After priming and filling procedure is completed, the
setting of the required pressure follows. On adjusting
the air operating pressure by air pressure regulator, the
working pressure rating of the air and material line
system components must be regarded.
According to the pressure ratio of the pump, the air
pressure will be transformed to a 50-times higher fluid
pressure.
⇒ See Operating and Safety Instructions of the
manufacturer / supplier of the complete material
dispensing system.
⇒ See 3.3‘Technical Data’ of pump.
On adjusting the air operating pressure observe:
• Always use the lowest pressure to achieve the
desired results and never exceed the permissible
max. working pressure.
• Reduce pressure
− if pump runs evenly but continuously exceeds
120 cycles per minute.
− if pump accelerates or cycles erratically, not allowing
the material to follow and to be taken in by the pump.
In case of malfunction see checklist and notes in
section ‘Trouble Shooting’.
If applicable: During initial operation check operation of
low level control (pump shut-off device) in time when
material in the container is running low. Re-adjust level
control if device should not operate just in time.
CAUTION Do not allow pump to operate when out
of material. Immediately shut off air to
pump!
5.3Standard operation.
Operate pump / equipment by qualified, instructed
personnel only.
Warning
Do not exceed the stated working
pressure of the airmotor/pump and
other system components.
Hands away from lower part of the
pump (material inlet) and all outlets for
the material.
Never attempt to disassemble pump/
equipment while system (pump and
system components) is pressurized.
Shut pump off in case of malfunction/damages or
changes in the behaviour of the pump during operation.
CAUTION
When using pump for applications, for example for filling
purposes, which require longer periods of time of
continuous pump operation, do not exceed pump cycle
speed of 75 cycles/min.
Shut pump immediately off when container is empty
before pump is out of material and ‘run-away’ condition
occurs.
Operation
Prior to operation (at least 1 x per working shift):
• Check pump / equipment visually for damages and
abnormal shape.
The operating of pump / equipment depends on the
individual design of the material dispensing system.
⇒ See Operating and Safety Instructions of the
manufacturer / supplier of the complete material
dispensing system.
Pump / airmotor are normally under pressure during the
operation mode. The pump starts when the material
outlet (shut-off valve, flow gun, etc.) is opened and
discharges the material. The material flows under
pressure from the outlet opened.
• Always disconnect air coupler from pump when
pump sits idle for long periods of time. Also perform
pressure relief procedure when equipment is shut
down. Depressurize material system by opening end
of line shut-off valve/flow gun and drain material into
a collecting can.
• In case of malfunction during operation, shut pump
off.
⇒ See checklist and notes in section ‘Trouble
Shooting’.
• When container is empty, immediately shut pump
off. Do not allow ‘run-away’ of pump!
− Disconnect air connecting hose from pump drive.
− Change material reservoir or refill.
Procedure and handling depend on the individual
design of the equipment.
− If using a follower plate, take care that follower is
seated onto the pumping material and all air is
expelled underneath the follower plate.
− Reduce air operating pressure to pump by air
pressure regulator before coupling air connecting
hose to pump drive.
