2.GENERAL DESCRIPTION
The Mini-SUMO lubrication pump series is particularly suited for dual line systems and progressive systems and can be adapted
to many needs without making mechanical changes, even after installation is complete. In fact, by selecting from a set of
components that are perfectly compatible with each other and easily assembled, it is possible to vary the pressure, the quantity
of the delivered lubricant, the type of lubricant and the type of distribution.
This constructive technique is main based on the following modules:
•Electric motor
•Pump body
•Two pumping elements
•Tank
•Outlet valves and unit (inverter, pressure control valve, etc.).
There is one load bearing structure for all versions, the dual pumping element constitutes the essential module.
The pump unit has only one outlet.
Two types of grease tanks and two for oil, with different volumes (10 or 30 kg) can be positioned on the pump casing, with
spatula and level indicators.
The electric Mini-SUMO pump is fully protected against the external environment and can run without problems in the most
severe ambient conditions.

5. MACHINE COMPONENTS
5.1. STANDARD PUMP COMPONENTS
5.1.1 FIXED FLOW RATE PUMPING ELEMENTS
The pump may be configured with two fixed flow rate pumping elements (25 cm^3/ min for each pumping element.
The seal between the piston and pumping element casing is dry, as the insertion of a gasket is not required.
The check valve for the pumping element is has a cone-shaped seal. This solution guarantees optimal system sealing at high
operating pressures (max pressure of 380 bar).
The pumping elements are mounted on the pump casing without the need to disconnect the line pipes with a threaded
connection, which makes assembly/disassembly easier.

5.1.2 MINIMUM AND MAXIMUM GREASE LEVEL INDICATORS
The standard grease pumps have two level types:
•Minimum laser level (for 10 and 30 Kg reservoir);
•Max visible level (floating).
5.1.3 Minimum laser level
The minimum level is realised by a laser probe. When the lubricant reaches minimum level, the laser probe signals the lack of
lubricant. The probe has two outputs, the first NO and the second NC when lubricant is present. When the minimum level is
reached, the probe signals that the lubricant is low.
The minimum level contact is indicated by a light signal on the electric panel. In addition the panel controls any automatic
reservoir filling pump command.
5.1.4 Max visible level (floating)
The phase that the lubricant is loaded in the tank is realised by the operator, who uses a pump.
Once the maximum lubricant level is reached, a rod is activated that indicates that the tank is full.
5.1.5 MINIMUM AND MAXIMUM OIL LEVEL INDICATORS
The standard oil pumps have two level types:
•Minimum and maximum level with a float;
•Max visible level (floating).
5.1.6 Minimum and maximum level with a float
A rod probe with a dual float mounted on the pump cover makes it possible to read the minimum oil level (reserve) and the
maximum level (which makes it possible to stop automatic tank filling).
The minimum level contact is indicated by a luminous signal on the electric panel, it also controls any automatic tank filling
pump command.
5.1.7SPATULA FOR GREASE AND OIL (STANDARD VERSION)
Two tanks have been foreseen with capacities of 10 and 30 kg. (22 – 66.1 Lb) two for oil and two for grease.
The tanks are supplied standard with a spatula and a scraper, which must not be disassembled during their assembly or
replacement. Under the spatula, there is a standard electrogalvanised steel mesh with 0.5 mm holes (0.02 in.). The pump is
protected from possible foreign bodies that could be inadvertently present while the tank is being loaded.
5.2. OPTIONAL PUMP COMPONENTS
5.2.1 Interchangeable electromagnetic change-over
An electromagnetically controlled inverter is available for dual line operation. The inverter can be replaced in the case of
damage without having to disconnect the two line pipes (interchangeable version). This reduces the maintenance time and the
time the plant is stopped.
The main change-over parts are:
•a casing with a central lapped hole that makes it possible
to make a dry seal connection with the inversion piston,
which is facilitated by a balancing system;
•a ground piston with a dual coupling surface, with grooves
that improve lubrication and the seal at high pressures;
•sealing gaskets that can support high pressure levels, by
means of a pressurised chamber, optimising the inverter
function;
•Two control electro-magnets
Advantages:
•easy to assemble and disassemble without disconnecting
the line tubes
•Minimum time the plant is stopped.

5.2.2 Electro pneumatic change-over
5.2.3 Hydraulic change-over (optional)
5.2.4 ELECTRIC EQUIPMENT
“DROPSA” electric equipment has been designed with the purposes of supplying a system that is complete with all commands
necessary for the automatic operation controlled by safety signals for centralised lubrication systems. The primary voltage is 400
VAC and 50 Hz, other voltages are provided upon request. For more information about the available versions, contact the
Dropsa technical sales department.
GENERAL NOTE FOR ALL ELECTROMAGNETIC INVERTERS:
A 2-5 second de-energising delay should be set for the electromagnets to permit them to complete their
inversion after the closing time for the end of line pressure switch.
The main change-over parts are:
•a casing with a central lapping hole that makes it possible to
make a dry seal connection with the inversion piston, which
is facilitated by a balancing system;
•a ground piston with a dual coupling surface, with grooves
that improve lubrication and the seal at high pressures;
•the inversion phase is facilitated by a balancing system;
•sealing gaskets that can support high pressure levels, by
means of a pressurised chamber, optimising the inverter
function;
•Two single acting pneumatic actuating cylinders, controlled
by a 5/ 2 type solenoid valve.

6. UNPACKING AND INSTALLATION
6.1 UNPACKING
Once the suitable location for installation has been identified, open the package and remove the pump. Check that it was not
damaged during transport or storage. The packaging material does not require special disposal precautions as it is not in any
way dangerous or polluting. Refer to the local regulations for disposal.
6.2 INSTALLATION
Pump assembly operations are not required.. The pump is fixed on a metal pallet that permits safe handling with a transpallet or
fork lift truck. The pallet was designed to be installed in the plant. It has four  14mm holes suitable for fixing to the floor.
Suitable space must be provided (as shown in the installation diagram) to prevent abnormal positions or the possibility of
impacts. Then, as described above, the pump must be connected hydraulically to the machine and then the connection to the
control panel must be made.
7. INSTRUCTIONS FOR USE
7.1 STARTING THE PUMP
Before using the MINI SUMO pump, a few preliminary checks must be performed:
•Check the integrity of the power supply cable and the unit prior to use.
•If there is damage to the power supply cable or the unit, do not start operations!
•Replace the damaged power supply cable with a new one.
•The unit may only be opened and repaired by specialised personnel.
•In order to prevent the danger of electrocution due to direct or indirect contact with live parts, the electric power supply line
must be suitably protected by a specific differential magnetothermic switch, according to regulations and with rated
breaking capacity at list equal to prospective fault current at installation point.
•It is prohibited to use the pump if submersed in fluids or in a particularly aggressive or explosive/inflammable environment if
not previously prepared for that purpose by the supplier.
•Use safety gloves or glasses as specified in the safety sheet for the lubricating oil
•DO NOT use aggressive lubricants with NBR gaskets. In the case of doubt, contact the Dropsa SpA technical office to receive a
detailed card about the recommended oils.
•Do not ignore the hazards to health and comply with the health regulations.
•Check the integrity of the pump.
•Check that the pump is at the operating temperature and that there are no air bubbles in the pipes.
•Check that the electric connection was carried out correctly.
•Once the pump has started, check that the direction of rotation of the electric motor is as indicated by the arrow on the
motor's protective casing; if it rotates backward; reconnect it as shown in the wiring diagram provided with the motor.
7.2 INSTRUCTIONS FOR USE
1) Press the start button on the machine to which the pump is connected or start it;
2) Check the that the pump starts;
3) To change the pressure value, turn the adjustment screw (see Chap. 5). Turn it clockwise to increase the pressure or counter
clockwise to decrease it;
4) Check that the machine lubrication is suitable (if there are doubts about correct operation, the Dropsa SpA technical office
can be contacted to request the inspection procedure).
ATTENTION:All components must be ground connected. This applies both to electric components as well as to control
devices. For this purpose, make sure that the ground wire is directly connected. For safety reasons, the ground conductor
must be approx. 100 mm longer than the phase conductors. If the cable is accidentally disconnected, the ground terminal
must be the last to be disconnected.

* To obtain a correct setting bring the lock ring to maximum setting value and then down to desire value.
On the pump is placed a label that shows the wiring diagram and setting values. The pump is normally equipped with pre setting
sensor to "L" thresholds (minimum level). Whereas other thresholds: MM (absolute maximum level), M (absolute level), LL
(absolute minimum level), can be set by the user.
7.2.2 Procedure for calibrating the capacitive probe nc (optional)
Before being assembled the capacitive probe must be calibrated in accordance with the following sequence:
1. connect the sensor electrically;
2. immerse the sensor in the lubricant, down to half of its length;
3. remove the sensor from the lubricant until it skims the surface of the lubricant;
4. at this point there can be two possible types of operation:
-If its status does not change its sensitivity must be reduced (by acting on the screws for adjusting sensor sensitivity) until its
state of excitation is reached.
-if its status changes, the sensor already possesses the correct sensitivity
5. after checking that the sensor has been correctly read, the sensor reading must be repeated at least three times
6. Tighten the capacitive probe on the probe carrier rod, complying with the following assembly height:
-450 mm (from below the cover up to the lower surface of the sensor) for a 30 kg tank
-900 mm (from below the cover up to the lower surface of the sensor) for a 100 kg tank.

description.
PROBLEM
CAUSE
SOLUTION
The electric pump does
not deliver lubricant.
The electric motor is not operating.
The tank is empty.
The pump does not prime. Cause for the
pump not priming:
•The motor is rotating in the inverse
direction (clockwise);
•The motor is rotating in the correct
direction, but the spatula is not rotating;
•Air bubbles in the lubricant.
The pressure control valve (bypass) was
calibrated at a value that is too low
Presence of dirt in the non-return valve
Check the connection between the motor and the
electric power supply line.
Check the motor windings.
Check that the motor terminal board connection
plates have been positioned according to the power
supply voltage.
Fill the tank.
Attention: if the tank emptied itself and the electric
signal indicating that the minimum level was reached
was not given, check the minimum level contact.
Remove the tank cover and check that the spatula
rotates clockwise and moves the lubricant; otherwise,
invert two of the three motor phases.
See above.
Disconnect the pump delivery pipe and bleed the
lubricant until the air bubbles have been eliminated.
The pump does not
pressurise.
There may be dirt on the pumping element
check valve cone.
Clean the pumping element check valve cone and
seat, bleeding the lubricant.
No minimum level
signal when there is no
lubricant in the tank.
Minimum level incorrectly regulated.
Check the correct operation of the level probe as
follows:
Check the correct level adjustment of laser probe.
Minimum level
selection, with lubricant
below the minimum
and pump operating.
Minimum level incorrectly regulated.
The control panel lamp always remains on: check the
electric connection and replace the laser probe if
necessary.
9. MAINTENANCE PROCEDURES
The pump was designed and built in order to minimise maintenance requirements.
To simplify maintenance, it is recommended to install it in an easy to reach position.
•Periodically check the pipe joints to detect any leaks. Furthermore, always keep the pump clean to be able to quickly detect
any leaks or defects.
•Check if the loading filter is clean after every 2000 hours of operation.
The machine does not require any special equipment for any control and/or maintenance activity. It is recommended to use
tools and personal protective devices suitable for use (gloves) and that are in good condition according to current regulations to
prevent damage to people or machine parts.
ATTENTION:
Make sure that the electric and hydraulic power supplies are disconnected before carrying out any
maintenance work.

13
In the case of doubts and/or problems that cannot be solved, do not try to discover the reason by disassembling machine parts,
but contact the DROPSA S.p.A technical office.
10. DISPOSAL
During machine maintenance, or if it is demolished, do not dispose of the polluting parts in an improper manner. Refer to the
local regulations for their correct disposal. When demolishing the machine, the identification plate and all other documents

13. HANDLING AND TRANSPORT
Transport and storage are carried out using a metal pallet with packaging on the side and a wood cover.
The pump is fixed on a metal pallet that permits safe handling with a transpallet or fork lift truck. The metal pallet was designed
to be installed in the plant. It has four Ø 14 mm holes suitable for fixing to the floor.
14. PRECAUTIONS FOR USE
The warnings about the risks involved in using a pump for lubricants must be read.
The operator must understand its operation and clearly understand the hazards connected to pumping pressurised grease.
Therefore we recommend the following:
•Check the chemical compatibility of the material with which the pump is built with the fluid to be pumped (see chap. 4). An
incorrect selection could cause, in addition to damaging the pumps and pipes, serious risks for people (spillage of irritating
products that are harmful to health) and for the environment.
•Never exceed the maximum operating pressure permitted for the pump and the components connected to it. In the case of
doubt, refer to the data specified on the machine plate.
•Only use original spare parts.
•If components must be replaced with others, make sure they are suitable for operating at the pump's maximum operating
pressure.
Note: Personnel must use protective devices, garments and tools in compliance with current standards with regard to the location
and the use of the pump both during work as well as during maintenance operations.
Electric current
Do not carry out any work on the machine before disconnecting it from the electrical power supply and making sure that no one
can reconnect it during the operation. All the installed equipment (electric and electronic), tanks and basic structures must be
connected to the ground line.
Inflammability
The lubricant used in the lubrication circuits is normally not an inflammable liquid. It is however necessary to adopt all the
possible measures to prevent that it comes into contact with very hot parts or open flames.
Pressure
Before each operation, make sure there in every branch of the lubrication circuit that there is no residual pressure that could
cause oil to spray when disassembling fittings or components. After long periods of inactivity, check the seal of all the parts
subject to pressure. Do not subject the fittings, pipes and pressurised parts to violent impacts. Damaged flexible pipes or fittings
are DANGEROUS and must be replaced.
Only original spare parts should be used.
Noise
Under normal operating conditions, noise emission does not exceed 70 dB “A” at a distance of 1 metre (39.3 inches) from the
pump.
Lift the equipment according to the direction shown on the cardboard package.
The machine components can support storage temperatures between
-20 to + 65 °C; however, to prevent damage, the machine must only be started up after the machine has reached a
temperature of +5 °C.
ATTENTION:The warnings about the risks involved in using a pump for lubricants must be read. The user must understand
its operation using the user and maintenance manual.
ATTENTION! Never try to stop or deviate any leaks with your hands or other body parts.
NOTE:
The pump was designed to operate with lubricants with a maximum rating NLGI 2.
Use lubricants that are compatible with NBR gaskets.
Any internal residual lubricant used for assembly and testing purposes is NLGI 2 oil

18
A comparison table is provided between the classification of NLGI lubricants (National
Lubricating Grease Institute) and the ASTM classification (American Society for Testing and
Materials) for greases for the values that concern the pump.
For further information about the technical specifications and the safety measures to adopt,
refer to the product safety sheet (Directive 93/112/EEC) relative to the type of lubricant
selected and supplied by the manufacturer.
15. GUIDELINES FOR USE
Compliance with the essential safety requirements and the provisions specified in the machine directive was checked by filling
out prepared check lists that are contained in the technical file.
Two types of lists were used:
•Risk assessment (UNI EN ISO 14121-1).
•Compliance with the essential safety requirements Machine Directive –EC 06/42).
The risks that were not completely eliminated, but considered acceptable, are specified below:
•Electrocution: this can only occur in the case of serious user incompetence.
•Use of unsuitable lubricant: the types of fluids that are not compatible with correct pump operation are listed below. *
•Contact with harmful fluids.
FLUIDS THAT ARE NOT PERMITTED
