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.
5 for 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.
2 Initial 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!
