2. Safety
2.1 General warnings
Before carrying out any operation on the pump, it is important to read this manual. Always observe the safety regulations
of the nation in which the pump is installed and the need to use specialised personnel in the various operations of
maintenance, operation, installation, etc. required during the life of the pump.
The main rules of conduct to be observed to work at a good safety level are the following:
The operations of installation, operation, maintenance, etc. must always be carried out by qualified and trained
personnel.
It is good practice to always wear the foreseen personal protection equipment without exception.
Always carry out all of the cleaning, adjustment and maintenance operations ensuring that the power supplies are
disconnected.
Never direct jets of water toward the electrical parts, even if they are protected by housings.
Never smoke during operation or maintenance, especially in the event that flammable solvents or materials are
used.
Do not damage the labels, signs and pictograms applied to the pump. In the event that they are damaged
inadvertently, replace them immediately with identical ones.
Checking the chemical compatibility of the pump construction materials with the fluid that you intend to pump. An
incorrect choice could cause, in addition to damage to the pumps and the lines, serious risk to personnel (leaking of
products that are irritants and harmful to the health) and to the environment.
Never exceed the maximum permitted operating pressure value for the pump and the components connected to it.
If in doubt, see the data on the machine's label.
Use only original spare parts.
If you must replace components with others, ensure that they are suitable to function at the pump's maximum
operating pressure.
DropsA S.p.A. will not be held liable for damage to people or objects stemming from improper use of the pump, tampering
with its safety devices or failing to observe occupational health and safety regulations.
ATTENTION
Never try to stop or deviate any leaks with your hands or other parts of the body.
ATTENTION
The warnings on risks using a lubricant pump implies must be carefully read. The user must be familiar with
operation through the Operation and Maintenance Manual.
2.2 Residual risks
DANGER
The pump was designed in such a way so as to reduce residual risk for personnel to a minimum. Nevertheless, we urge caution and
attention in carrying out maintenance operations. Unfortunately, the familiarity achieved through frequent contact with the pump often
leads to forgetting or underestimating any risks.
The hazards that have not been entirely eliminated, but that have been deemed acceptable, are listed
below:
Contact with lubricant during maintenance or filling the reservoir
During the maintenance phase, low pressure spurts of lubricant are possible. (For this reason,
maintenance operations must be carried out using suitable PPE, in accordance with the prevailing
regulations).
Protection from direct or indirect contact with the lubricant must be ensured by the machine user.

5
Use of unsuitable lubricant.
The characteristics of the lubricant are indicated both on the pump and in this Operation and
maintenance manual (in the event of any doubt, contact the Dropsa S.p.A. Technical Office):
Electrical current
No operations must be carried out on the machine before disconnecting it from the electrical power
supply and ascertaining that no-one can reconnect it during the operation. All of the installed
equipment (electrical and electronic), reservoirs and base structures must be connected to the
ground line.
Electrocution
This can occur only in the event of serious negligence by the user who, however, is qualified.
Flammability
The lubricant used in the lubrication circuits is a fluid that is not normally flammable. In any case, all
possible measures must be taken to prevent it coming into contact with very hot parts or naked
flames.
Pressure
Before any operation, check for the absence of any residual pressure in all branches of the lubricant
circuit, that could cause spurts of oil or grease in the event that fittings or components are
disassembled. After long periods of inactivity, check the seal on all the parts subject to pressure. Do
not subject the fittings, pipes and the parts under pressure to violent impact. A damaged hose or
fitting is DANGEROUS. Replace it.
We recommend using only original spare parts.
2.3 Pictograms
Some pictograms are applied on the pump with warning and safety symbols for the operators.
Carefully read and familiarise yourself with the symbols and their message before using the pump.
ELECTRICAL HAZARD
You are close to electrical connections (protected) but accidental contact with them may cause electrocution and even death.
LASER RADIATION HAZARD
DropsA S.p.A. will not be liable for damage to people or things dues to the failure to observe the
regulations indicated by the pictograms or their imperfect preservation.

3. Machine description
The MINISUMO II range of lubrication pumps are particularly suited for dual-line and progressive systems and can adapt to
many needs without mechanical modifications, even after installation. In fact, be choosing a set of components that are
perfectly compatible with one another and easy to assemble, you can vary the pressure, the quantity of lubricant
distributed, the type of lubricant or the type of distribution.
This construction technique is based essentially on the following modules:
Motor
Pump body
Two pumping elements
Reservoir
Valves and output assemblies (inverter, pressure adjustment valve, etc.).
The bearing structure is the same for any version. The dual pumping element constitutes the essential module.
The pumping element normally has only one outlet, but the version with separate outlets can be requested.
Two types of grease and oil reservoirs with different volumes (10 or 30 kg~22 or 66 lbs) can be arranged on the pump
body with stirring paddle and electric level indicator.
The MINISUMO II electric pump is fully protected against the external environment and can operate without difficulty
even in the most severe environmental conditions.
3.1 Intended use and prohibited use
3.1.1 Intended use
The MINISUMO II pump is the ideal electric DropsA pump for use with single and dual line systems.
Lubrication systems engineered with the Dual Line System are generally used on large scale machinery and in harsh
operating conditions to lubricate multiple points on large machines.
NOTE: The pump is designed to work with maximum NLGI 2 grade lubricants.
Use NBR gasket compatible lubricants.
Any residual lubricant inside that was used for assembly and testing is NLGI 2 grease.
A table is shown that compares the NLGI (National Lubricating Grease
Institute) and ASTM (American Society for Testing and Materials)
categories for greases, limitedly to the values that involve the pump.
For further information on the technical characteristics and the safety
measures to adopt, see the Product Safety Data Sheet (Directive
93/112/EEC) related to the type of lubricant selected and supplied by
the manufacturer.

3.5.1 Inverters
For the inverter technical specifications and the methods of use, see the specific product manuals attached to the pump.
3.5.2 Fixed fixed flow rate pump elements
The pump is configured with one or two fixed flow rate pumping elements (110 cm^3/ min for each pumping element).
The seal between piston and pumping body is a dry type since it has no gasket in between.
The pumping element check valve is the tapered seal type. This solution allows an outstanding seal of the system to be
guaranteed at high operating pressures (max pressure of 400 bar – 5800 psi).
The pumping elements are mounted on the pump body without the need to disconnect the piping of the line with a
threaded connection, which makes it easy to assemble/disassemble.

3.5.3 Minimum and maximum level indicators for grease/oil
3.5.3.1 Laser for grease minimum level (optional)
The minimum level is achieved by a laser probe. The probe is normally closed when there is grease.
When the minimum level is reached, the probe signals the lack of lubricant.
For connections and setting see Par. 6.1.1 and 6.1.2.
3.5.3.2 Floating switch minimum/maximum level sensor for oil
A dipstick probe with dual floating switch mounted on the pump cover allows the minimum oil level
(reserve) and the maximum level (that allows the interruption of automatic reservoir filling) to be
read.
For connections, see Par. 6.1.3.
3.5.3.3 Floating switch visual maximum level for grease/oil
The filling phase of the lubricant in the reservoir is carried out by the operator with an appropriate
pump.
Once the maximum level of lubricant is reached, the rod that indicates that the reservoir is full
intervenes.
3.5.4 Grease and oil stirring paddle (standard execution)
Two reservoirs have been provided with capacity of 10, 30 and 100 kg. (22-66 – 220 lbs).
As standard, the reservoirs have the stirring paddle and the scraper that do not need to be
disassembled in the event of disassembly and replacement of the same. As standard equipment,
under the stirring paddle there is an electrogalvanized steel mesh with 0.5 mm (0.02 in.) holes. There
pump is thereby protected from any foreign objects that could be inadvertently present during the
reservoir filling phase.
3.6 Electrical equipment
“DROPSA” electrical equipment is designed for the purpose of providing a system complete with all
the controls needed for operation of centralized lubrication systems that is automatic and controlled
by safety signals. The primary supply voltage is 400 Vac and 50 Hz. Other voltages are available on
