1 Technical description
The Mini forms part of UTIFORM’s long trajectory in manufacturing mixing pumps for
bagged material. These machines mix the material to a homogenous consistency while also
allowing the hydro-mechanical transport of the material by means of a perpetual screw pump.
The Mini pump is loaded with bagged material. Compared to the traditional systems, this pump
has a more functional structure, while requiring less maintenance, and is particularly suitable for
mixing and conveying prepared mortars and dry premixed material such as adhesive for tiles,
structured mortars and plaster as well as mortar for plastering. The Mini is ideal for those
situations where an immediate availability of material is more important than the pumping
capacity.
The machine itself comprises a dry material deposit which has the mixing tube
connected to it at the bottom. At the top of the dry material deposit there is a motor reductor with
its corresponding cover which activates the mixing beater by means of a stop shaft. The
transversal bar of this then activates the perpetual screw of the mixing pump eccentric situated at
the bottom of the mixing tube.
The mounted perpetual screw pump comprises an auto adjustable and fixed (stator)
cover for the perpetual screw, and a perpetual screw for the eccentric (rotor) made of a material
highly resistant to wear and tear. With this system the nuisance of having to adjust and retighten
the stator screw is avoided.
To avoid damage during transport the machine’s chassis is installed with both the
electronic control panel and other control devices as well as the valves to regulate the exact
amount of water in the mix.
2 Operating mode
The operating mode is similar to that of a mixing pump. The dry material deposit is
loaded with the bagged material. The dry material falls into the dry area of the mixing tube and
the motor reductor makes the mixing beater turn. The mixing beater has spiral screw threads
which bring the dry material to the wet area of the mixing beater. A small joint provides a
continuous jet of water which can be regulated with precision. The dry material and the water are
mixed together in the shortest possible time and are transformed into a mass which can be
pumped and is ready to use.
The single screw pump installed at the bottom of the deposit transports the mixture
through the flexible pipe with a pumping capacity of up to 20 l/min, and brings it to the
projecting lance. The pump can be activated or deactivated by means of a remote pneumatic
control installed in the projecting spout. The pressure control valve in the water measuring
device makes the machine stop if the water pressure is insufficient. To enable ease of transport
the machine has two rubber-encased wheels that turn and two fixed ones, which makes it easier
to manoeuvre on a building site.

4 General safety guidelines
In order to make working with the Mini easier and safer we have listed here the most
important safety regulation which should be followed to avoid any danger when working with
the machine.
INSTRUCTIONS FOR USE
1.- The MINI is designed to mix, convey and spray mineral building materials. The
machine should only be used for the tasks for which it has been designed and the manufacturer’s
User Manual should be followed at all times.
2.- The machine should only be used by experienced personnel (machinery operators)
who have been previously instructed in the operating procedures and maintenance. They should
be familiar with its workings and have read the User Manual thoroughly.
3.- The machine should be positioned firmly on the site and secured so that there are no
unwanted movements.
4.- Machines that run on electricity need to be connected to a suitable feeder socket (one
that has a protector switch in the case of defective electrical currents).
5.- The machine must be installed at a safe distance from high scaffolding and should be
protected against any possible damage from falling objects.
6.- The conveying pipes must be fixed in such a way that any strain is absorbed by
adequate filtration points (hooks for pipes). This is especially important for pipes in a raised
position.
7.- The conveying pipes must also be positioned in such a way that no damage will
occur. If they cannot be laid completely straight and must be laid with a curve, then the radius of
the curve should be no less than six times the exterior diameter of the pipe.
8.- Use only original UTIFORM high pressure pipes for materials. These come with
built in couplings.
9.- Before switching on the machine you should check that nobody will be put in danger
by doing so.
10.- When the machine in used you must check that the conveying pipe has sufficient
prelubrication, that is, that the material used can be easily pumped and that there are no points
left unsealed at the joints of the pipe.
11.- Both in the case of activation or failure of the security devices, the machine must
be stopped until the problem has been eliminated.
12.- Before opening the conveying pipe system or any other component of the
conveying system that is under pressure, you must first check that there is no pressure in the
system.
13.- Blockages in the pipes must be eliminated following the instructions in this User
Manual. The person in charge of carrying out this operation must position himself where he will
not be reached by spraying material. Nobody else should be in the surrounding area.
Mini Pump 7
14.- Security and accident prevention devices should not be removed or modified, and
these must be handled correctly.
15.- Whenever the machine is being cleaned or repaired it should be turned off at the
mains switch, otherwise the pneumatic remote control could start up the main motor by itself.
16.- Before starting the machine the operating safety of this must be checked. As soon as
any faults are detected, or even indications of these, they should be eliminated immediately and
the personnel supervisor notified. In the case of finding any faults that may endanger operating
safety, use of the machine must be interrupted.
17.- If an accident happens as a result of not having respected the safety measures given
here, or the safety measures in the work place as established by professional associations or by
the insurance company with relation to civil responsibility or your country’s legislation, or
caused by negligence, then the legislator will hold the machine operator responsible or, in the
case that this person could not be held responsible due to lack of training or basic knowledge,
then the personnel supervisor will be held responsible.
For all these reasons, when you are working with the Mini, please do so with caution and bear in
mind the safety measures that apply in each case (safety measures for the association of
construction professionals relative to conveyors and spraying machines).
Below you will find some brief safety instructions to be followed for the correct
use of this machine onsite.

Mini Pump 10
5 Start-up
5.1 Installation of the machine
The Mini pump must be installed on the flattest surface possible and secured by
activating the two wheel brakes. The compressor and driving motor connectors must be
connected to the electricity sockets supplied for this purpose on the electronic control panel.
There can be no confusion because the connecting sockets and cable lengths are different.
The main motor switch must be placed in the “0” position. The additional cleaning
connection and release valves on the water valves must also be closed. Also check that the
material stop valve is closed.
5.2 Electricity supply point
Use only a special three-pole 3*2.5 mm
construction work. In order to avoid voltage losses, the electricity cable must always be unreeled
completely!
To ensure proper operation of this machine, it is very important that the power supply is
230 V at the machine’s power supply inlet.
5.3 Water supply point
The water hose, which is resistant to creases and high pressures, must be completely
unreeled; it must have a minimum interior diameter of 3/4”. It must be connected to a suitable
tap and any air inside the hose must be eliminated. The water pressure gauge needle must
indicate a minimum pressure of 3.5 bars; this can be achieved by installing a pre-fitted pump to
increase water pressure between the water supply network and the machine.
2
section and 1 KV electricity cable for
WARNING!
5.4 Product hose placement and lubrication
The Mini pump is equipped with an original factory-supplied hose fitted with quickfitting couplings. The hose distance must be as short as possible. We recommend moistening or
lubricating the hose interior to prevent it from becoming blocked. To do so, a coupling is
connected to the machine to establish the hose cleaning connection; the hose is filled with water
and the water is allowed to run out of the end.
5.5 Connection of the air hose and spraying lance
Unreel the 3/8” air hose, which is resistant to pressure and creases, next to the product
hose and connect it to the machine air outlet. When this is done, the compressor hose must be
connected to the air pressure gauge and the connection plug to the corresponding electricity
socket on the electronic control panel. The spraying lance is connected to the other end of the air
hose and the air spray gun is adjusted (the diameter of the product hose nozzle is equal to the
distance of the air gun on the spraying lance).
5.6 Checking the rotation direction
- Lower the head motor and remove the beater. Put the motor back in its vertical
position.
- Disconnect the water hose from the mixing tube.
- Activate the head motor, compressor and, finally, main switch (red and yellow).
- The motor must rotate in the direction indicated by the arrow on the protective part of
the motor fan (anti-clockwise, i.e. to the left).
Mini Pump 11
- If it rotates in the wrong direction, the phases on the lower part of the electricity input
plug must be rotated.
WARNING! If the plug is changed or a main cable extension cable is not used, check
the rotation direction again.
5.7 Loading of air into the water regulator
Disconnect the water hose from the mixing tube and leave it in the bucket. Press the
electrovalve release button until no bubbles appear in the flow metre.
5.8 Adjustment of the water regulator
While the water valves are being loaded with air, regulate the desired amount of water by
pressing the electrovalve release button. Open the water control valve until the buoy reaches
approximately 400 l/h.
Note: The amount of water actually required by the product that is being mixed is
regulated later by the machine during operation until the desired product consistency is
obtained.
5.9 Pressure test of the perpetual screw pump (stator- sleeve)
The Mini pump is equipped with a maintenance-free pumping element (according to
customer’s request); its pumping pressure is optimally adjusted to the conditions at the work site
(according to both material consistency and composition and hose length and diameter).
Normally, the pumping elements not requiring maintenance are used until they reach their limit
of wear, i.e. until the supply flow is reduced substantially or the consistency of the material
ranges between thick and fluid. In these cases, the pump elements must be replaced.
If the wear of the maintenance-free set of pumps has to be controlled or if retensionable
sets of pumps are used, pump pressure is calculated as follows:
WARNING! The water hose is connected to the upper connection of the mixing tube,
the pump motor is lowered and the beater is removed from the mixing chamber. Activate
the electrovalve release button and let water enter the mixing chamber until it covers the
top of the perpetual screw (rotor).
In order to ensure that the water level in the mixing chamber does not continue to rise
while the pressure is being adjusted, disconnect the water hose from the mixing tube.
The process described below would be performed in the case with the option of the
pressure regulator:
After placing the mixer back in the tube and repositioning the head motor fixed with the
safety valve, connect the hydraulic pressure regulator to the sleeve outlet with the release valve
open. After briefly starting the head motor (approximately 1 or 2 seconds), the air is eliminated
from the pressure regulator. The release valve is then closed and the head motor is reactivated for
a few seconds; at the same time, monitor the oscillation of the pressure valve indicator needle.
The upper oscillation value of the pressure valve corresponds to the regulated pressure of
the pump!
Mini Pump 12
Hydraulic check rule: if flat plaster is applied using a Dn 25 pipe measuring up to 10 metres in
length, the pressure valve must read 15 bars.
5.10 Amount of water required
Immediately before starting the work, make sure that sufficient water is in the mixing
chamber (covering the rotor head). If this is the case, introduce water into the mixing chamber
following the instructions described in the previous point; if this is not done, dry material may
penetrate the sleeve.
WARNING!: Failure to comply with the foregoing will lead to premature wear and
tear or even breakage of the sleeve in a fraction of a second when the pump motor is
started with dry material and without water.
5.11 Machine start-up
Activate the main switch and start the pump motor by pressing the green start button. Set
the motor speed using the speedometer inside the control panel display. Regulate the speed
according to the machine’s input voltage; if the voltage is low (around 200-210 V), we
recommended setting the speed to approximately speed position Nº 4 i.e. 40 Hz. working speed.
Use the control valve to regulate the consistency of the material by adjusting the water
flow until you achieve the desired working conditions.
Stop the main motor and connect the product hose to mixing tube outlet. Control the
consistency of the material at the end of the hose. With the machine stopped, connect the
spraying lance to the product hose. Regulate the water level until you achieve the desired
consistency.
WARNING!: When regulating the amount of water, bear in mind that any changes in
consistency due to hose length will only be reflected in the corresponding delay that occurs in
the spraying lance.
Mini Pump 13
5.12 Spraying
The material (mortar or plaster) is applied continuously and horizontally, line by line. The
prior condition necessary for continuous work is that there must be sufficient material in the
hopper at all times. The level of dry material in the hopper must never fall below the perpetual
screw pump axle.
Continuous spraying may be achieved by using the correct rubber nozzle on the spraying
lance (diameter 14 mm.). The distance between the spraying lance and the wall must be
maintained at between 15 and 30 cm. The pump must be placed in a position that ensures the
shortest possible hose length (10 metres). Hose extensions produce greater pressure in the
transportation of the hose and consequently greater wear and tear of the pump parts.
6 Speed Variator
This machine incorporates a speed variator or single-phase frequency converter (2.2 kW).
The incorporation of this device on the Mini pump provides a machine input power of 230 V,
allowing the pump’s main motor to operate at 230 V (three-phase).
When the variator is powered on the power elements together with a certain number of
control components are connected to the power supply.
After disconnecting the variator power, wait for one minute before reusing the device.
This time corresponds to the electric discharge time constant of the condensers.
Do not touch these elements: they are extremely dangerous.

7 Interruptions in Operation
7.1 Brief interruptions
In order to transfer the machine from one place to another, simply disconnect the machine
using the spraying lance cut-off valve. This will stop the head motor automatically. Turn off the
main switch and stop the material conveyor so that no moisture penetrates the dry material
hopper.
WARNING!: Remember that in the event of work interruptions during operation, the
spraying lance must always be placed with the material nozzle facing downwards,
otherwise the material that continues to run out will obstruct the air diffuser.
7.2 Long interruptions in work and completion of work
In the event of interruptions in work that exceed material setting times (end of spraying),
the following procedure may be performed to clean the mixing chamber and material hoses
thoroughly:
- Stop the head motor by placing the switch to the “0” position.
- Remove the beater from the mixing tube and replace it with the cleaning tool.
- Briefly start the head motor and various times and then introduce the cleaning scraper
in the mixture tube. This will eliminate material remains deposited in the mixing tube
and allow them to be pumped through the product hose.
- Check that the material hose has no pressure. To be safe, disconnect the hose (look
away and use protective glasses!) from the pump outlet.
- After removing the cleaning tool, clean, dry and replace the mixture tree. Dry
material may stick to the beater (mixer) if this is moist when activated and
may cause faults.
- Remove the rubber nozzle from the spraying lance and wash it thoroughly with water.
- Connect the cleaning adapter to the product hose and introduce the rubber ball under
pressure. This ball is pressurised through the hose by the thrust of the water, thus
cleaning the hose. The rubber ball remains trapped in the spraying lance diffuser.
- After closing the cleaning connection, disconnect the spraying lance from the hose
and then remove the hose from the cleaning connection.
WARNING!: In order to prevent foreign bodies from entering the hose, connect both
hose end couplings after you have unreeled the hoses. This will prevent faults caused by
foreign bodies from occurring.
Mini Pump 21
- Once the air diffuser has been removed from the spraying lance, the rubber ball may
be removed. Clean the air diffuser using the nozzle cleaning tool and running water.
Clean the spraying lance with water. Make sure that the material nozzle housing is
completely clean and that the nozzle is not pressurised by the pressure of the material
in the spraying lance.
- During longer pauses in work, and as a minimum whenever work has been completed,
water must be removed from the regulator, particularly when there is danger of frost
forming (cold areas); this can be done by opening both release valves. Air must also
be injected into the water valves; connect the compressor to the machine water inlet,
disconnect the water hose from the mixing tube and with the release valves open,
inject air using the electrovalve release button. The compressor is activated using the
main switch.
WARNING!: By removing water in both summer and winter you will have no
unpleasant surprises due to frost!
- Particularly when working with smooth plaster, clean the pump outlet at least once a
day; otherwise material may be deposited in the pump outlet that can cause higher
pressure and, consequently, greater wear and tear of pump components. By loosening
both fastener screws, the sleeve support device on the mixture tube can be easily
disassembled in order to clean the chamber thoroughly.
- The dry material hopper only has to be cleaned when working with a different class of
dry material or when the machine is prepared for use during prolonged periods of
time.
7.3 Stoppage of the machine
If the Mini pump is not used for prolonged periods, e.g. during winter, we recommend
that you unscrew the sleeve rotor and perform the cleaning work described in the previous point.
In this way, sleeve contour deformations are avoided and the rotor is prevented from becoming
stuck.
Mini Pump 22
8 Service and maintenance
Make sure that the machine is not turned on accidentally when maintenance work and
repairs are being performed (disconnect the current entry).
The Mini pump has been built in such a way that it requires only minimum maintenance.
However, in order to ensure perfect operation, the mixing tube, beater and material hopper must
be free of hard material remains at all times.
The electronic control panel must be kept dry and free of dust inside. Whenever
necessary, remove dust from the control panel using a vacuum cleaner and after disconnecting
the pump from the mains. We do not recommend blowing compressed air since dust lifted as a
result is deposited on the connection contacts and may render these unusable.
The reducer motors are lubricated for their entire working lives. However, if any grease is
expelled, it must be replaced with ENERGREASE or a similar lubricating substance. If this
happens, make sure not to exceed the specific amounts. Also, make sure that no material is stuck
to the stator refrigeration wings or ventilator.
The York absorption valve of the water hose from the drum to the machine must be
cleaned daily before starting work and the pressure reducer filter must be cleaned once a week;
in order to perform this last operation, use the special valve supplied with the machine.
WARNING!: When assembling the filtering deposit, make sure that the ring seal is
correctly positioned.
Whenever necessary, use a damp cloth to clean the water metre indicator tube. If the
indicator tube has turned dark in colour due to interior adhesions, remove the tube by loosening
both joint screws and clean it inside using a cloth. Never use a metallic brush or similar device!
In order to ensure that the air diffuser can move freely inside the spraying lance tubing at
all times, grease this slightly after cleaning.
Before performing any maintenance or cleaning work on electrical equipment,
remove the plug from the mains.
and apply a little grease to the contacts. This will ensure the proper functioning of the connectors
and prevent the contacts from burning.
Remove and shake the filter disks on the extraction side of the membrane compressor and
on the other side at least twice a week when cleaning the interior and every 14 days when
cleaning the exterior. In this respect, make sure that the filters with thick soft surfaces are placed
outwards and the thin hard surface filters inwards.
From time to time, remove the electrical connectors from the control panel
Mini Pump 23
9 Faults and corrective actions
Faults in the Mini pump can be eliminated very simply by performing a small number of
operations. When eliminating these faults, it is essential that you comply with the following
rules:
1. Before opening the control panel door, disconnect the machine from the mains!
2. Whenever working with moving parts of the machine, turn off the main switch or
remove the plug from the power supply socket!

working.
The consistency of
the material is too
liquid or varies at
irregular intervals.
The water rises in the
mixing chamber
when the machine is
not being used.
The machine cannot
be stopped using the
pneumatic control
and/or the
compressor does not
stop during pauses in
work.
Regulate the water slowly by reducing the water
level until achieving the desired consistency.
The parts of the pump are
worn.
With free maintenance pumps, assemble new parts
and if necessary use a pump with a greater supply
pressure.
The material hose is
blocked.
Not enough dry material is
being fed into the pump.
Eliminate any obstructions in the hose.
Refill the material tank with dry material (the level
of dry material must never be below the perpetual
screw pump axle)
Excessive water affluence.
Regulate the water slowly by reducing the water
level.
Material is stuck to the
mixing beater.
Stop the machine using the main switch, lower the
head motor, remove the mixing beater, clean, dry
and reassemble.
Faulty electrovalve. Unscrew the upper part of the electrovalve and
remove it carefully, since it has pretensioned
springs inside. Clean the control drill as well as the
membrane and reassemble the electrovalve.
Leaking air valve.
Check the air tightness of the air hose and the
connections and change defective parts.
Defective compressor.
Check the pressure of the compressor on the
pressure valve of the water input by connecting the
compressor to this. If a minimum of 3 bars of
pressure is not achieved, the compressor must be
repaired at the Service workshop.
Badly set pressure valve
(air pressure valve).
Ask the Service workshop to check the operation
of the pressure thermostat and reset this if
necessary (start = 1.1 bars; stop = 2.5 bars)

10 Accessories
You may extend the scope of application of the pump with original Mini pump
accessories and thus improve the handling of your equipment.
In numerous applications of the Mini pump, material is loaded by pneumatic conveyor
equipment from either a static or pressurised silo. In these cases, an airtight insufflation hood is
placed on the dry material recipient of the device in order to channel the dry material and also
filter dust from the supplied air. The dome of the hood is capped by a large filter, and also has an
inspection hatch that can be closed, as well as a rotating vaned probe with a socket for
connecting the control cable for the pneumatic conveyor equipment for static silos, or a device
for pressurised silos. Four eccentric locks are fitted to the sides of the machine, fastened by
hooks under the profiled moulding of the machine’s material recipient, and which securely fasten
the insufflation hood, rendering it fully dust-proof.
You can find many more accessories and all necessary spare parts in our catalogue,
including details of prices, tools and spare parts.
Use only original spare parts and accessories for purchased equipment!
