6. UNPACKING AND INSTALLING THE PUMP
6.1 UNPACKING
Once a suitable location has been found to install the unit remove the pump from the packaging. Check the pump has not
been damaged during transportation or storage. No particular disposal procedures are necessary, however packing
should be disposed of in accordance with regulations that may be in force in your area or state.
6.2 INSTALLING THE PUMP
No particular assembly operations are provided.
Pump must be fixed to floor. On this purpose, pump bracket has been provided with 4 holes, Ø 8.5 mm (0.33 in). Then,
pump must be pneumatically connected to the machine (see par. 5.1).
Furthermore, we recommend:
To leave minimum 100 mm (3.93 in.) space around the pump in order to avoid unnatural posture or possibility
of sustaining impacts.
Not to install pump submerged into fluids or in aggressive/explosive/inflammable environments, if not
preventively provided for this purpose by the supplier.
To use gloves and safety glasses, as required in the lubrication oil safety chart.
Not to use aggressive lubricants with NBR seals. If any doubt, please contact Eng. Dept. of Dropsa S.p.A. We will
provide you with a detailed chart of recommended oils.
Not to ignore dangers to health and observe all hygienic standards.

7. PUMP OPERATIONS
After installing the pump, adjust driving air pressure.
7.1 Prior to pump start-up
Verify the unit is undamaged.
Check that pneumatic and electric connections (IEC 64/8, IEC 364) have been carefully carried out.
Refill the reservoir with compatible lubricant.
Verify operating temperature [MIN temperature: -5°C (+23°F)].
7.2 Pump start-up
Verify piping are air-bubble-free.
Verify that lubrication is correctly carried out.
8. TROUBLESHOOTING
The following diagnostic table indicates the main anomalies which may be encountered, the probable causes and possible
solutions. If you cannot solve the problem, do not attempt to disassemble parts of the machine but contact the Eng.
Dept. of DROPSA S.p.A.

characteristics (see ch. 4)
9. MAINTENANCE PROCEDURE
Pneumatic-driven Pump, Series 3414…. require only minimal maintenance.
To facilitate maintenance, it is suggested to install the pump in an easily accessible location (see paragraph 6.2).
Machine does not require any special tool for checking or maintenance tasks. However, it is recommended the use only
of appropriate and in good conditions tooling, protective devices (gloves) and clothing to avoid hazards to equipment
or persons.
9.1 How to disassemble the pump
-Empty the reservoir;
-Disconnect the piping;
-Unscrew the fixing screws;
-Remove the reservoir;
-Remove the pump and the provided filters;
-Unscrew the pneumaticcylinder from pump;
-Remove all the other components.
WARNING: The unit can only be opened and repaired by authorized Dropsa personnel.
CAUTION!
Prior to any maintenance and cleaning task, discharge pressure from pump and from the respective
connected piping.

5
Before the reassembling all pump components must be washed with petroleum and lubricated.
Periodical checks:
VERIFICATION
WORK CYCLES
State of lubrication
100
Lubricant level

Cleanliness of refilling filter
400
Cleanliness of return filter (where provided)
400
Cleaning of the bottom of reservoir in presence of sediments
600
Furthermore:
Keep the machine unit clear and check pipe joints to readily detect possible leaks.
10. DISPOSAL
During maintenance or disposal of the machine care should be taken to properly dispose of environmentally sensitive
items. Refer to local regulations in force in your area. When disposing of this unit, it is important to ensure that the
identification label and all the other relative documents are also destroyed.

13. HANDLING AND TRANSPORTATION
Prior to shipping, Pneumatic-driven Pump, Series 3414…. is packed and in cardboard containers. During transportation
and storage always maintain the pump the right way up as indicated on the box. On receipt check that the packaging has
not been damaged and store the pump in a dry place. Pump may be handled without any special lifting apparatus.
Lift the equipment observing the right way up shown on the cardboard packing.
During storage, machine components can withstand temperatures –20°C÷+50°C (-4°F÷ +122 F°).
However, in order to avoid damages, machine start-up should occur at a minimum temperature of +5°C
(+41°F).
14. OPERATING HAZARDS
It is necessary to read and understand the possible hazards and risks involved when using a lubrication pump. The
operator must fully understand the hazards implied in pumping grease under pressure.
Inflammability
Lubricant generally used in lubrication systems is not normally flammable. However, it is recommended to avoid contact
with extremely hot substances or naked flames.
Pressure
Prior to any intervention, check the absence of residual pressure in any branch of the lubricant circuit as it may cause
lubricant squirts when disassembling components or pipe fittings. Do not subject the connections, the piping or parts
under pressure to violent impacts. Damaged piping or connections are DANGEROUS and should be immediately replaced.
Noise
During normal operating conditions the pump does not produce excessive noise less than 70 dB(A).

15. PRECAUTIONS
Verification of compliance with the essential safety requirements and Machine Directive dispositions has been carried
out filling in checking lists provided and contained in the technical file.
Dropsa used three kinds of checking list:
List of hazards (according to the EN 414 as it refers to EN 292);
Enforcement of the essential safety requests (Machine Directive –06/42);
Electric safety requirements (EN 60204-1)
Here follows a list of dangers which have not been fully eliminated but which are considered acceptable:
During assembly or maintenance, oil squirts at low pressure can occur. (For this reason suitable personal
protective clothing must be worn and appropriate protective measures must be taken during such operations).
Contact with lubricant during refilling /maintenance -> Protection against direct and indirect contact must be
provided by the user. (See the requirements for the use of suitable individual protective measures).
Preloaded spring in driving cylinder or reservoir where provided.
Use of incompatible lubricant -> fluid characteristics are shown on the pump and in the User and Maintenance
Manual (in case of doubts, please contact Dropsa S.p.A. Eng. Dept.).
Use of incompatible lubricant.
