Storage and Maintenance
Pumps are delivered in appropriate carton boxes. Packaging material should be properly disposed. Handling and
storage of the new pump do not require any special procedures.
However after the pump has been used, empty the used
oil in the suction tube into an appropriate container. This
is done by overturning the pump. The dust in compressed
air can slow down and even block the motor cylinder. The
following steps may prevent this from happening:
1) Let in 50 gram of air tool oil into the air inlet hole
weekly, operate the pump for several minutes after filling lubricator.
2) Turn on the pump for several minutes until moving parts
is fully lubricated.
3) You may repeat the above operation if necessary.
4) The above steps should be carried out on a weekly
basis.
For the pumps that are attached with compressed air
treatment equipment, please empty the water retained in
the reservoir of the filter-purger frequently. For the pumps
that are attached with a lubricator, please pay close attention to the lubricator’s oil level
and refill with SAE 20, SAE 30 or antifreeze oil for extreme
conditions when necessary.
Note:
The user should perform only routine maintenance operations (such as filters, silencers, cleaning…) with the pump
in order not to damage it or compromise its safety.
Contact our sales or service center when the pump
needs further maintenance.
General Safety Regulations
When the pump is connected to the compressed air
supply:
1. The compressed air must be filtered to avoid dust and
moisture into pump
2. The max compressed air pressure must not exceed
0.8Mpa/120psi
3. To deliver oil, pull the trigger on the delivery pistol;
delivery stops when the trigger is released but the
whole system remains under pressure
4. Position the gun so that the circuit can’t open
accidentally. Otherwise oil could leak onto the ground
5. Never point the pistol at people or object.
6. Pull the gun trigger
7. Always cut off the air supply after use so that oil can’t
leak out in case one of the pump’s components should
break
8. Use only original spare parts in case the pump has to
be repaired or its components have to be replaced
9. Empty all the oil from the pump in case it has to be
disposed of
10. When not in use, turn off compressed air to stop pump
11. Do not use the pump near open flames. Do not smoke
during this operation
12. Wear oil-proof gloves
13. Do not throw the oil away. Used oil has to be disposed
of according to environmental regulations
14. The pumps can be used only to deliver lubricants,
used oil or antifreeze liquids. Do not use the pump for
any other substance
How to Use
Directly Fitted Pump into the Drum
1. Insert the suction tube of pump into the drum and
secure with ring nut, suitable for commercial drums with
2” bung opening.
2. Fit a oil delivery hose for oil outlet of the air operated
pump using only high quality hoses (normally 1/2” by
means of 3/4” fitting.
3. Oil delivery pistol NPT threaded: Connect delivery hose
with delivery pistol using suitable pipe fittings.
4. Air inlet connection is 1/4” quick plug ( or 1/4” NPT
female) in all versions. Compressed air connection (
to be supplied by the customer) should be done using
suitable plumbing.
5. A pressure regulator to keep the pump’s working pres
sure at the best possible level (max 70-115 psi / 5-8
bar) is recommended between the pump and the compressed air line
6. A valve can enable the operator to stop the pump at any
given moment by cutting the air supply off between the
pump and the compressed air line
7. Slowly open the compressed air valve that feeds the
pump. It will start to operate, priming automatically and
filling the feed circuit with oil. The pump is now prepared for its usual function.
