TYPE OF PUMP:
BELTED WITH TROLLEY
COAXIAL
-MECHANICAL VARIATOR
-ELECTRONIC VARIATOR

The self-priming electric pump with rubber impeller is suitable for the transfer of delicate food liquids even in the
presence of suspended bodies (such as wine, milk, oil, de-stemmed grapes, fruit juices), and a wide range of
chemical substances.
The electro pump is able to work in both directions of rotation. The pump body is made entirely of AISI 304
stainless steel, while the impeller is made entirely of rubber for food use (Certificate N° 2218 del 05/11/98; N°
2218/b del 05/11/98; N° 2844 del 30/11/98 in accordance with D.M. del 21/03/73 e D.M. n° 220 del 26/04/93).
In the COAXIAL and with INVERTER models the pump is connected directly to the crankshaft, while in the
"BELT TRANSMISSION" models the pump is connected to a pulley connected to the engine with transmission
belts; on the MECHANICAL VARIATOR and REDUCER models the pump is connected to a cardan shaft.
In each model the pump can be easily opened to allow ordinary cleaning and maintenance operations to be carried
out by the qualified staff.
The models EURO 20, EURO 30, EURO 40, EURO 50, EURO 60 can be provided with BY-PASS: a valve in
stainless steel AISI 304 is placed externally to the body pump, which allows you to adjust the pressure as you like.
It is not to be used to regulate the flow, but it allows to close the outlet pipe and let the product recycle for a few
seconds avoiding overloads to the engine (ATTENTION max 10 sec. to avoid problems of overheating and / or
damage to the product).
The electric pump consists of the following components:
-ENGINE
-TROLLEY (optional in the coaxial models)
- MOTOR PULLEY (where provided)
-PUMP PULLEY (where provided)
- BELT (where provided)
-PUMP SUPPORT
-RUBBER IMPELLER
-MECHANICAL SEAL
- STAINLESS STEEL DISC
- STAINLESS STEEL SHAFT
-ELECTRICAL PANEL
The electric pump must be positioned firmly in a stable and horizontal position with respect to the ground (operate
the brake of the wheels in the models provided with them), and the level of the liquid to be transferred must be at a
maximum depth not exceeding 5/6 meters from the axis of the pump, and the aspiration system must be below the
liquid level of at least 10-15 cm.
Checks before installation: before connecting the machine, make sure that the motor voltage (shown on the plate)
corresponds to that of the mains and that the switch is set to the "Zero" stop position. The electrical safety of this
machine is allowed only if it is connected to an effective earthing system, performed according to current electrical
standards. The verification and possible installation of the appropriate electrical components must be carried out by
qualified staff. Furthermore, the use of multiple sockets or adapters is not recommended; if their use is
1. DESCRIPTION
2. POSITIONING, CHECKS AND INSTALLATION

indispensable, it is necessary to use only products that comply with current safety standards, respecting the flow
limit in current value and maximum power.
Pipe connection: the pipes must be rigid and reinforced, and must be fixed to the pump by means of special
clamps, avoiding the formation of bottlenecks that could prevent the regular flow of the liquid.
IMPORTANT: never start the machine when empty (in the absence of liquid). The first time the machine is
started, it is necessary to carry out a preliminary washing in order to remove any manufacturing remains.
The EURO self-priming electric pumps are driven by an electric motor (made in compliance with all current safety
regulations), whose switch, when the machine is off, must always be positioned on the "central zero".
To start, the switch must be set to the desired speed, or to position "1" for models with only one speed. The mouth
of the pump which will suck the liquid is determined by the direction of rotation of the impeller, which can be
controlled by observing the rotation of the van on the back of the engine.
STARTING:
the starting mode varies according to the model purchased.
SINGLE PHASE COAXIAL MODELS:
On this type of pump, the electrical panel is equipped with a double condenser: one for commissioning (standard
on all single-phase motors) and a special boost condenser to guarantee additional power during start-up.
In addition to the "0" stop position, the rotation inverter also presents position 1 (clockwise rotation), position 2
(counter clockwise rotation) and position with AVV spring start, indicated both after number 1 and number 2.
To start the machine, turn the switch in the required direction for 2 seconds in the AVV position, which must be
released as soon as the pump starts running.
CAUTION: Do not insert the switch in the AVV position, otherwise you risk damaging the internal boost
condenser. FOR THE EURO 20 MODEL an electric solution is provided.
The AVV position is not present, but after the pump has been stopped, it needs to wait for 5 seconds before a new
start.
If the pump is supplied with automatic stop and start systems (for example pressure switch or flow switch), in
single-phase coaxial versions, it is not possible to invert the direction of rotation (except for the EURO 20 model).
THREE-PHASE COAXIAL MODELS, WITH INTEGRATED PANEL:
3. FUNCTIONING

On EURO 20-30-40-50-60 coaxial models with integrated electrical panel, the pump has an inverter installed on
the electric motor. In addition to the stop position "0" on the rotation inverter, position 1 (clockwise rotation) and
position 2 (counter clockwise rotation) are also indicated.
To start the machine, simply turn the inverter in the required direction.
THREE-PHASE COAXIAL MODELS WITH SEPARATE PANEL:
The three-phase coaxial models with separate panel show up with a control panel installed on a trolley.
In addition to the rotation inverter, they have a magnetic protection switch, which must be activated after
connecting the pump to the mains. To activate it, simply press the BLACK button.
Then to start the pump, turn the inverter to the required position. On these models it is possible to stop the machine
either by positioning the inverter on "0" or by pressing the emergency stop button.
CAUTION: after pressing the emergency stop, to reactivate the pump, turn the button in the direction of the turn
signal and activate the magnetothermic switch again.
DOUBLE SPEED MODELS WITH BELT TRANSMISSION:
On these models a separate control panel is installed, complete with magnetothermic protection and multipolar
rotation inverter. The inverter has a central "0", three positions on the left (102) and 3 positions on the right (102).
The number 1 indicates the minimum speed in both directions. The number 2 indicates the maximum speed in both
directions.
For operation of the magnetothermic protection see paragraph "Three-phase coaxial models with separate panel".
SINGLE-PHASE MODELS WITH BELT TRANSMISSION:
These models have an integrated control panel on the electric motor. For operation, see paragraph "Single-phase
coaxial models".

MODELS WITH MECHANICAL SPEED VARIATOR:
This type of pump is available only with THREE-PHASE motorization, and has a separate control panel installed
on the trolley. For the operation of the panel, see paragraph "Three-phase coaxial models with separate panel".
Attached to this manual there is a specific section dedicated to the operation of this type of pumps.
MODELS WITH ELECTRONIC SPEED VARIATOR:
See specific paragraph at the end of the manual.
In addition to the above models, the pumps can have the following special control panels:
1) CONTROL PANEL WITH AUTOMATIC PRESSURE SWITCH:
Available on all three-phase models (except for the EURO 20 pump) and on models with electronic variator (both
three-phase and single-phase).
The pump is equipped with a special fitting consisting of a non-return valve, buffer tank (in some cases it is not
supplied) and a pressure switch panel. This fitting is installed on the pump in the liquid delivery direction (check
the direction of the turn signal indicated on the non-return valve, which must coincide with the liquid direction).
The power supply is given by the pressure switch panel, which in turn is connected to the mains. Inside the
pressure switch panel there are the adjustment screws to set the pressure for insertion and disconnection of the
pressure switch circuit.

To operate the pump, after making the electrical connection, position the rotation inverter at position 1 in the
desired flow direction. The pump will start running. When the delivery circuit is closed (usually with a tap or
dispensing gun), the pump will continue to run for a few moments until the set pressure is reached.
CAUTION: When first used, open the valve located above the buffer tank to allow all the air in the circuit to
escape and avoid foam problems.When the circuit is reopened, for a few moments the liquid flows out due to the
push of the internal pressure and then the pump is activated.
The two adjustment screws located inside the pressure switch allow to establish the stop and restart time of the
pump.
CAUTION: for models equipped with an electric variator, a connection is provided between the pressure switch
and the control panel. The power supply on these models is always supplied to the general panel and not to the
pressure switch. On the general panel there is an AUTOMATIC / MANUAL selector to select operation with the
pressure switch or in manual mode.
MAKE THE ADJUSTMENTS IN THE FOLLOWING ORDER:
1) INSERTION: To increase the insertion point when the pressure decreases, screw the calibration nut
(1)
2) DISINSERTION: To increase the operating point when the pressure increases, screw the differential
adjustment nut (2)
CONTROL PANEL WITH FLOW SWITCH: ("Dry Stop")
This is an accessory available on all three-phase models (except EURO 20) and on all versions with electronic
variator (both single-phase and three-phase). The pump is supplied with a special stainless steel fitting on which
the flow sensor is installed. The fitting must be installed on the delivery pipe of the product, making sure that the
turn signal on the sensor corresponds to the direction of the product. In the absence of liquid, the sensor stops the
pump. To activate the pump on the control panel, in addition to a manual / automatic selector, there is a BY PASS
button. In case of automatic operation, it must be pressed to allow the pump to start and fill the pipes, temporarily
interrupting the flow switch sensor control. Once the pipes are filled, the button must be released and the pump
will continue to work, stopping in the absence of the liquid.

3) CONTROL PANEL WITH ON / OFF RADIO CONTROL:
This is an accessory available on all three-phase pump models (except EURO 20). On models with electronic
variator, a specific radio remote control is provided. The ON / OFF radio remote control simply allows the pump
to be switched on and off remotely, even if the direction and speed can not be changed. On the control panel there
is a selector for the operation of the machine with radio control, or with local commands. The direction of travel
and speed (on models with mechanical or double speed variator) must be set on the control panel.
In the case of a pump with an electric variator, the remote control has the function of switching on, switching off,
varying the speed, changing the direction of rotation. On the pump control panel there is a selector to control the
machine remotely or with the commands on it.
The maximum distance of use varies according to the rooms in which it is used. It is advisable to perform signal
tests before using the pump.
4) PANEL WITH SETTING TIMER:
Available on all models with three-phase motorization.
FUNCTIONING:
After starting the engine, priming takes place after a few moments; if more than 10/13 seconds pass, turn off the
engine and disconnect the power cable, check the correct fixing, and the lack of holes in the supply pipes as they
can cause air infiltration. If the machine is provided with by-pass, it is possible to act on this valve in order to
increase (valve closed) or decrease (valve open) the flow rate as you want.
IMPORTANT: the by-pass must be closed at the beginning of processing and for the suction of solid parts.
To switch off the machine, simply position the engine switch on the "center zero".
In the event of an emergency stop, it is necessary to restart the machine in the reverse direction of rotation, and
immediately reverse the rotation, thus allowing the elimination of any bodies that prevent the rotation of the
impeller.
After the use, it is necessary to wash the machine in order to preserve its mechanical and hygienic characteristics.
It is necessary to run the machine for a few minutes with clean water, proceeding then with the complete emptying
of the liquid contained in the pipes and in the pump body. For sanitization, use warm water with clinical solutions
for washing and sanitizing, with concentrations compatible with the rubber components of the machine.
If a lasting stop of the machine is expected, it is advisable to introduce a few drops of glycerine oil into the pump,
then reactivate the pump for a few seconds.
Maintenance: all the pump components are checked and adjusted in the factory before shipping. So the machine
does not need any special maintenance, but only regular checks over time, which also increase the duration of the
machine.
IMPORTANT: These checks must be carried out by qualified personnel and with the machine disconnected
from the power supply.
The checks to carry out are the following:
Check the impeller wear
4. CLEANING AND MAINTENANCE

Check the transmission belts wear
Check the sealing gaskets. For replacement, remember to clean both surfaces of the seal with alcohol to
remove oil and grease remains
Check the bearing
Check the lubricating oil in models with speed variator.
In case of any repair operations it is necessary to use the original spare parts by contacting the retailer or directly
the manufacturer.

MECHANICAL MOTOVARIATOR INTEGRATION
The pump is equipped with a mechanical variator, installed on a trolley with a control panel separate from the
motor body.
The manual handwheel with gravitational indicator allows you to vary the speed from 190 to 900 rpm.
Attention: the speed must be changed only with the pump running and not with the engine switched off.
Different operations may cause the variator to break down.
The variator is supplied with lubricating oil and an indicator of the quantity of oil present inside it.
The control panel is equipped with the following components:
Motor protection switch with absorption regulator. When starting the machine for the first time, and
after a power failure, press the black reset button.
Rotation inverter: allows to stop and change the direction of rotation of the pump.
Emergency stop: in case of danger allows the pump to stop immediately.
ELECTRONIC MOTOVARIATOR INTEGRATION
The pump is equipped with an electrical panel for controlling the speed and the various switch-off / switch-on /
inversion functions. The electric motor installed is with separate ventilation (servoventilated). The servoventilated
motor is always powered at 220V single-phase.
The pump has been adjusted to parameters that allow it to work in an optimal speed range: from 0 to 890 rpm.
Inside the electrical panel the inverter display is visible, on which the values of the output frequency of the motor
appear, and at each variation Hz correspond approximately 20 rpm (for example 20 Hz correspond to about 400
rpm; 30 Hz correspond to about 600 rpm).
However, it is possible to see on the display the number of rotations per minute corresponding to the value of the
Hz to which the pump works, entering with the keyboard in the programming system of the inverter and carefully
following the instructions of the "User Manual".
However, it is advisable to keep the inverter parameters on the values set by the factory; and in any case any
variation of the parameters must be carried out by expert personnel. To change the direction of rotation, it is
advisable to set the pump to average speed values, because the machine's starting capacity is reduced if the speed is
too low.
ATTENTION: Models with integrated reducer can work at maximum power at any speed.
The components on the panel are the following:
GENERAL SWITCH: it is used to switch on the pump panel, turning the selector switch to position 1. To
stop the pump completely, set it to 0. The panel switch-on allows the power supply and immediate
activation of the cooling fan installed on the electric motor.

WIRED REMOTE CONTROL: with power selector and reversing and switching commands, it must be
connected to the panel through the appropriate connector. The REMOTE mode must also be selected on the
panel to activate operation with the remote control.
LOCAL / REMOTE control: it is used to set the pump functioning with the remote control (REMOTE),
or with the start and stop commands on the electrical panel (LOCAL).
FAUL INVERTER: it is the warning alarm that indicates a power overload for the electric variator. In
case of lighting, turn the pump off, wait about 30 seconds and restart it. This light can switch on in the
following cases:
oas a result of prolonged use of the pump at very low rotations: simply increase a little the
rotation speed.
oDifficulty in starting: increase a little the starting speed and check the impeller wear.
oDifficulty in reversing the direction of rotation: increase the rotation speed and check the
impeller wear status.
oFailure of the electronic variator: contact the dealer or the manufacturer.
FLOW SWITCH: this accessory must be connected to the appropriate connector on the electrical
panel, and with the appropriate terminals to the outlet port of the pump. The function is to stop the
pump in the absence of liquid. It is activated by positioning the appropriate selector on
FLUSSOSATO. In the first use, to allow the pump to fill the pipes, it is possible to bypass the sensor
by keeping the BY-PASS FLOW SWITCH pressed. As soon as the pipes are filled with liquid, release
the button and the pump will continue to work automatically.
PROBE: the pump is prepared for the connection of a further external probe with open / closed signal
(for example pressure switch or level probe). Position the selector on Probe for automatic operation.
GEAR SELECTOR: allows the pump to start and the direction inversion. On position 0, the pump
stops.
POTENTIOMETER: allows speed adjustment from 0 to 800 (maximum speed set by default). On
some models, in addition to the inverter electric panel, a pre-couple reducer is installed to increase the
engine power in the phase of reduced speed and rotation reversals. On this version the electric motor is
not servoventilated.
