determined by the type of reducer fitted to the electric motor. The flow rate varies between 0,2÷1cm³ e da 1÷5cm³. The
operating pressure is 4 bar. It is suitable for oil with a viscosity of 32÷250 cSt at a fluid working temperature between +5
°C and +40 °C.
Should it be required to use a different specification product, prior authorisation should be obtained from Dropsa S.p.A.

2.5 VA at 60 Hz. Admissible voltage variation is ±10%.
Protection grade IP 54
insulation class - F
continuous service - YES
Reservoir: made of transparent plastic material in 1 L version and white plastic in 1.7 L version.
Minimum level indicator
Magnetic type
Reversible float with contact normally open at rest. To convert to normally open contact turn the float upside down. The
maximum power is 50 W ÷ 50 VA; the maximum voltage is 220 V ac – 150 V dc.

6. HANDLING AND TRANSPORTATION
Prior to shipping, the equipment is carefully packed in cardboard package. During transportation and storage, always
maintain the pump the right way up as indicated on the box. On receipt check that package has not been damaged. Then,
store the machine in a dry location.
7. PRECAUTIONS
It is necessary to carefully read the warnings and risks associated with using a lubricant pump. The operator must
understand how it works and must clearly understand the dangers by studying the user manual.
Power supply
Any type of intervention must not be carried out before unplugging the machine from power supply. Make sure that no
one can start it up again during the intervention.
All the installed electric and electronic equipment, reservoirs and basic components must be grounded.
Flammability
The lubricant generally used in lubrication systems is not flammable. However, it is advised 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 oil
sprays when disassembling components or fittings.
Noise
Pump produces noise, not more than 70 dB(A).

8. OPERATING HAZARDS
The micro pump has no particular contraindications except for the following points:
•Contact with fluid for breaking / opening of adduction piping. -> The operator must be equipped appropriate
individual protective devices DPI.
•Unsuitable postures. -> See paragraph 9.2.
•contact with oil -> see instructions for using appropriate individual protective devices DPI;
•Use of an inappropriate lubricant -> fluid characteristics indicated both on the pump and in the manual (if in doubt
consult our Technical Office);
UNACCEPTABLE FLUIDS
Fluids
Dangers
Lubricant with abrasive additives
High consumption of contaminated parts
Lubricant with silicon additives
Jamming of the pump
Benzine – solvents – inflammable liquids
Fire – explosion – damage to gaskets
Corrosive products
Corrosion of the pump – injuries to persons
Water
Pump oxidation
Food substances
Contamination of these substances
9. UNPACKING AND INSTALLING
9.1 UNPACKING
Once a suitable installation position has been identified, unpack the pump and prepare for installation. It is important to
inspect the pump to ensure that there has been no damage during transportation. The packaging material used does not
require any special disposal procedures. You should refer to you regional requirements.
9.2 PUMP INSTALLATION
There are no installation operations of pump.
Allow sufficient space for install with 100mm clear space around the perimeter of the pump.
Mount the pump at “eye level” to avoid any risk of postural problems. There are two fixing holes on the plate, with
different distances depending on the 1 Lt and 1.7 Lt version.
Afterwards is necessary connect he pump to the machine with hydraulic connection, refill the reservoir and connect to
the control panel.
Empty the reservoir during the disassembly phase.
Disconnect electrical and hydraulic parts.
9.3 HYDRAULIC CONNECTIONS
Only connection is to be made from the pump to the lubrication point or the metering valves.
9.4 ELECTRICAL CONNECTIONS
Before carrying out any wiring, ensure that the correct power supply is available. Refer to the identification label on the
Pump. In order to avoid dangers of electric shock it is important to remove all power before installation or maintenance.
All electrical components and control devices must be grounded. Make sure that the ground wire is correctly connected.
For safety reasons, the earth conductor should be approximately 100 mm longer than the phase conductors. In case of
accidental cable detachment, the ground terminal must be the last to come off.
In order to prevent dangers of electric shocks due to direct or indirect contact with the energized parts, electrical power
supply line must be protected by a suitable magneto-thermal circuit breaker with an intervention threshold of 30mA and
1 millisecond minimum operating time.
Circuit breaker power must be = 10 kV and nominal power in In = 6 A.
N.B.: after all connections make sure that pipes and cables are appropriately fixed and protected from impacts.

10. INSTRUCTIONS FOR USE
10.1 START UP
Damage to the power supply cable and housing can lead to contact with high voltage parts and present a danger to life:
•Check the integrity of the power supply cable and the unit prior to use.
•Where the cable or the unit is damaged do not operate the equipment!
•Replace the power supply cable with a new one.
•The unit should be opened and repaired ONLY by qualified personnel.
•The pump MUST NOT be submersed in fluids or utilised in environments which are particularly aggressive or
explosive/inflammable if not prepared for this purpose beforehand by the supplier.
•For correct fixing verify the distance between centres.
•Use gloves and safety glasses as required in the lubrication oil safety chart.
•DO NOT use aggressive lubricants with NBR gaskets and seals; if in doubt consult the Engineering Department of
Dropsa SpA, who will provide a chart with the details of recommended oils.
•DO NOT ignore dangers to health and observe all hygiene standards.
10.2 ACTION TO BE TAKEN PRIOR TO START UP
•Verify the integrity of the pump;
•Fill the reservoir with suitable lubricant (min/max indication on the reservoir);
•Ensure the pump is at working temperature and the tubing is free of air pockets;
•Ensure that any electrical connections have been effected correctly (CEI 64/8, IEC 364);
10.3 REGULATION
The only parameter which can be modified is the flow rate; turn adjustment knob clockwise (decrease) or unclockwise
(increase).

11. TROUBLESHOOTING
Below is a diagnostic table showing the main faults, the probable causes and the possible solutions.
In the event of doubts and/or problems which cannot be solved, do not proceed to look for the fault by dismantling
parts of the machine, but contact the Dropsa Technical Office.

SOLUTION
The pump does not deliver
grease or does not deliver the
correct amount of grease

Faulty motor
•Refill the tank and vent the air from the
system
•Wash the filter with kerosene and blow
through with compressed air
•Tighten all the connections ensuring
there are no leaks
•Replace Pump

The pump fails to deliver oil at
the prescribed pressure
unclean or broken check valve
broken or damaged pipes and
discharge fittings
•
Change valve
•Change discharge pipe or tighten
fittings
12. MAINTENANCE PROCEDURES
Ensure the pump is positing so that it can be verified easily.
Ensure you have necessary personal protective equipment to avoid any contact with the grease.
The pump undergoes severe factory testing therefore no maintenance is forecasted with the pump.
DropsA recommends the use of lubricants that are free of any impurities as well as a regular cleaning of the pump’s
components.
Periodically check that the pump is intact and does not present leaks. As required, or at least once a year, clean or
substitute the refilling cod.: 3130101.
Periodically it is necessary to check:
VERIFICATION
WORK CYCLES
The oil level
Check the oil level in the reservoir
The state of lubrication
1000
Cleanliness of the loading and suction filters
2000
The cleaning of the bottom of the tank if deposits are present
6000
The machine does not require any special equipment for any checking and/or maintenance activity, however the
recommendation is to use suitable equipment which is in a good condition (according to current regulation) in order to
avoid causing damage to persons or machine parts.
Make sure that the electric and hydraulic supply has been disconnected before carrying out any maintenance
intervention.

13. DISPOSAL
In the course of machine maintenance, or if the machine is scrapped, do not dispose of polluting parts into the
environment. Refer to local regulations with regard to their correct disposal. When scrapping the machine the
identification plate and any other documents must be destroyed.
