WARNING: Read carefully and understand all
INSTRUCTIONS before operating. Failure to follow the safety
rules and other basic safety precautions may result in serious
personal injury.
A. MACHINE DESCRIPTION
PUMP: Self-priming, volumetric, diaphragm pump, equipped with internal by-pass valve.
MOTOR: Asynchronous motor, single-phase, 2 pole, closed type (protection class IP55 in conformance with
EN 60034-5-86 regulations) self-ventilated.

C. OPERATING CONDITIONS
C1. ENVIRONMENTAL CONDITIONS
TEMPERATURE: Min. -10oC（14℉） / Max. +60oC(140℉)
RELATIVE HUMIDITY: Max. 90%
ATTENTION!
The temperature limits should be adhered to, to avoid possible damage or malfunction.
C2. ELECTRICAL POWER SUPPLY
Depending on the model, the pump must be supplied by a single-phase alternating current line whose
nominal values are shown in the table in Paragraph B1 – ELECTRICAL SPECIFICATIONS.
The maximum acceptable variations from the electrical parameters are:
Voltage: +/-5% of the nominal value
Frequency: +/-2% of the nominal value
C3. WORKING CYCLE
The pumps are designed for continuous use under maximum back pressure.
ATTENTION!
Functioning under by-pass conditions is only allowed for brief periods of time (2-3minutes
maximum).

C4. FLUIDS PERMITTED
PERMITTED
• Chemical products: Urea, weak acid & weak alkaline fluid etc.
• Water
D. MOVING AND TRANSPORT
Given the limited weight and size of the pumps (see overall dimensions), moving the pumps is simple and
does not require the use of lifting devices.
E. INSTALLATION
E1. DISPOSING OF THE PACKING MATERIAL
The packing material does not require special precautions.
Refer to local regulations for disposal.
E2. PRELIMINARY INSPECTION
• Check that the pump has not suffered any damage during transport or storage.
• Clean the inlet and outlet openings, removing any dust or residual packing material.
• Make sure that the motor shaft turns freely.
• Check that the electrical specifications correspond to those shown on the identification plate.
ATTENTION!
THE MOTORS ARE NOT ANTI-EXPLOSIVE TYPE. Do not install them where inflammable vapours can
be present.
E3. CONNECTING THE TUBING
• Before connection, make sure that the tubing and the suction tank are free of dirt and thread residue that
could damage the pump and its accessories.
• Before connecting the delivery tube, partially fill the pump body with Adblue to facilitate priming.
• Do not use conical threaded joints that could damage the threaded pump openings if excessively tightened.
SUCTION TUBING:
- Minimum recommended nominal diameter: 3/4”
- Nominal recommended pressure: 10bar / 145psi
- Use tubing suitable for suction pressure
DELIVERY TUBING:
- Minimum recommended nominal diameter: 3/4”
- Nominal recommended pressure: 10bar/145psi
ATTENTION!
It is the installer’s responsibility to use tubing with adequate characteristics.
Loosening of the connections (threaded connections, flanging, gasket seals) can cause serious
safety issues.
Check all the connections after the initial installation and before each use.
Tighten the connections, if necessary.

F. DAILY USE
a. If using flexible tubing, attach the ends of the tubing to the tanks. In the absence of an appropriate slot,
solidly grasp the delivery tube before pumping.
b. Before starting the pump, make sure that the delivery valve is closed (dispensing nozzle or line valve).
c. Turn the ON/OFF switch to ON. The by-pass valve allows functioning with the delivery closed only for brief
periods.
d. Open the delivery valve, solidly grasping the end of the tubing.
e. Close the delivery valve to stop dispensing.
f. When dispensing is finished, turn off the pump.
ATTENTION!
Function with the delivery closed is only allowed for brief periods (2-3 minutes maximum).
After using, make sure the pump is turned off.
G. PROBLEMS AND SOLUTIONS
PROBLEM POSSIBLE CAUSE CORRECTIVE ACTION
The Motor is not turning
The motor turns slowly when
starting
Low or no flow rate
Lack of electric power Check the electrical connecting
Motor Problems Contact the Service Department
Low voltage in the electric power
line
Low level in the suction tank Refill the tank
Filter clogged Clean the filter
Excessive suction pressure
High loss of head in the delivery
circuit (working with the by-pass
open)
By-pass valve blocked
Air entering the pump or the
suction tubing
A narrowing in the suction tubing
Low rotation speed
The suction tubing is resting on
the bottom of the tank
Cavitation occurring Reduce suction pressure
Bring the voltage back within the
anticipated limits
Lower the pump with respect to
the level of the tank or increase
the cross-section of the tubing
Use shorter tubing or of greater
diameter
Dismantle the valve, clean and/or
replace it.
Check the seals of the
Connections
Use tubing suitable for working
under suction pressure
Check the voltage at the pump.
Adjust the voltage and/or use
cables of greater cross-section
Raise the tubing
Increased pump noise
Leakage from the pump body Diaphragm damaged Check and replace the diaphragm
Irregular functioning of the
by-pass
4 OF 6
Dispense fluid until the air is
purged from the by-pass system
H. MAINTENANCE
All models are designed and constructed to require minimal maintenance.
In any case, always bear in mind the following basic recommendations for maintenance:
- On a weekly basis, check that the tubing joints have not loosened, to avoid any leakage.
- On a monthly basis, check the pump body and keep it clean of any impurities.
- On a weekly basis, check and keep clean the line suction filter.
- On a monthly basis, check that the electric power supply cables are in good condition.
I. NOISE LEVEL
Under normal working conditions the noise emission from all models does not exceed the valve of 75 db at a
distance of 1 meter from the pump.
J. DISPOSING OF CONTAMINATED MATERIALS
In the event of maintenance or demolition of the machine, do not disperse contaminated parts into the
environment. Refer to local regulations for their proper disposal.
