1 INTRODUCTION AND SAFETY
This manual contains basic instructions to be observed during installation, use and
maintenance. This manual must be consulted by the installation personnel and by
all qualified personnel chosen by the installation manager to follow its operation.
Furthermore, the manual should always be at hand in the site where the pump is used.
1.1 Identification of the codified instructions in this manual
WARNING: General danger; failure to observe these safety instructions may
cause personal injury.
WARNING: Electrical hazard; failure to observe these instructions may cause
an electric shock with consequent risk of serious injury or death.
WARNING: Hot surface; failure to observe these safety instructions may cause
personal injury.
Risks deriving from failure to comply with safety regulations
Failure to comply with safety regulations may cause physical injury or material damage
as well as possible environmental contamination. Failure to comply with safety
regulations may lead to the complete loss of warranty rights.
To cite some examples, non-compliance with the said regulation may cause:
•
breakdown of the main functions of the machine or of the installation,
•
compromised maintenance operations,
•
physical damage of an electrical, mechanical nature.
1.1 General Information
This pump has been made according to the most recent and advanced techniques, in
full compliance with current standards and has been subject to strict quality control.
This manual will help you understand its function and learn its possible applications.
The user manual contains important recommendations necessary for correct and
economical operation.
The recommendations should be observed in order to guarantee the reliability, lifespan
and to prevent accidents deriving from improper use.
The pump should not be used outside the limits described in the technical
specifications. It is necessary to observe the instructions regarding the nature, density,
temperature and volume of the pumped liquid, rotation speed and direction, pressure
and motor power as well as all the other instructions contained in this manual or the
documentation attached to the contract.
The data plate indicates the model, the main service specifications and the serial
number. It is important to provide these indications when requesting repairs or support
and for requesting spare parts.
The manufacturer declines all liability for any damage that may, directly or
indirectly, be caused to people or things as a result of failure to observe all of
the provisions indicated in the instructions manual provided and in particular
the warnings concerning installation, use and maintenance of the electric pump
or in conditions other than those specified on the data plate. The warranty
expires definitively in the case of negligence or incorrect use of the product.
WARNING: This equipment must not be used by children or persons with
reduced physical, sensory or mental abilities, or lacking in experience and
expertise, unless supervised or instructed.
WARNING: Children may not use the equipment, nor may they play with the
pump or in the immediate vicinity.
2 PRELIMINARY INSPECTION
2.1 Delivery and packing
The pumps are supplied in their original packing, in which they should remain until the
time of installation. Check that the packing is free from damage.
If the product appears to be damaged, inform the retailer immediately. Take care not
to bend the pump when the packing has been removed: this may cause misalignment
or damage to the pump itself. The pump should not be exposed to needless shocks
or impact.
2.2 Packaging contents
The packaging contains the product use and installation manual. In the case of an
electric pump, the packaging also contains the motor manual.
3 STORAGE AND HANDLING
3.1 Storage:
Storage temperature: from -5°C to +40°C
The pump and the motor must be kept in a dry, sheltered place, away from heat
sources, dirt and vibrations. If the pump has not been packed, it should be kept in
storage vertically, to prevent any misalignment.
3.2Handling:
WARNING: Please observe the current accident prevention standards. Risk of
crushing. The pump may be heavy. Use suitable lifting methods and always
wear personal protection equipment.
Before handling the product, check its weight (see fig. 2) to identify suitable lifting
equipment.
WARNING: The eyebolts supplied with the motors should not be used to
handle the whole assembled electric pump (see fig.1.D).


VERTICAL MULTI-STAGE PUMPS
For handling a pump with a motor of up to 4kW, use the belts wound around the pump
head, taking special care not to damage the side coupling covers in fig.1.A. For pumps
with a motor equal to or over 5.5 kW, use belts or chains attached to the lifting eyes on
the motor flange as shown in fig.1.B.
WARNING: There is a risk that the pump may overturn during handling; make
sure that the pump remains in a stable position during handling.
If there is no motor, use a belt wound around the pump head, paying particular
attention not to damage the side coupling covers (fig.1.E), or the lifting eyes on the
motor flange as shown in figure 1.F, if present. The eyebolts on the motor of the pumps
must be used exclusively to handle the motor alone (see fig. 1.C). Extract the pump
from the packaging and check that it is in good condition. Check also that the plate
data correspond to those required. For any defects, contact the supplier immediately,
reporting the nature of the same.
4 GENERAL DATA
4.1 General description
This product is a non self-priming vertical multi-stage pump, which can be combined
with normalised IEC electric motors. The pump is suitable for pumping hot or cold
water The metal materials in contact with the liquid in the standard versions are:
• stainless steel in the models MVX 3/6/10/15,
• stainless steel and cast iron in the models MVX 30/45/65.
Versions completely in stainless steel are available for the models MVX 30/45/65.
only the pump has been purchased, please refer to power P2, to the number of
revolutions indicated on the data plate and to fig.2 for choosing the correct motor size.

Permitted Use
The pump is suitable for:
•
Civil and industrial water distribution systems,
•
Irrigation,
•
Water treatment,
•
Washing systems,
•
HVAC (heating and cooling)
Forbidden use
The pump is not suitable for:
• Pumping liquids not compatible with the product construction materials.
• Pumping hazardous liquids (for example toxic, explosive, inflammable or corrosive
liquids),
• Pumping food grade liquids other than water (for example wine or milk),
• Pumping liquids containing abrasive, solid or fibrous substances,
• Working outside of the rated capacity field specified on the data plate.
Examples of unsuitable installation:
• Environments with explosive or corrosive atmospheres,
• Outdoor installations without protection from atmospheric agents (e.g. sun, rain,
high or freezing temperatures).
WARNING: Do not use this pump for inflammable or explosive liquids.
Misuse may create hazardous conditions and cause personal injury and
material damage. Misuse of the product may nullify the warranty.
Special use
Contact the sales and support service in the cases below:
• If the pump is used to pump liquids with viscosity or density greater than water (a
motor with a proportionately higher power should be used).
• The water to be pumped has been chemically treated (softened, chlorinated,
demineralised etc.),
• In any other situation other than those listed under permitted use.
4.2 Technical data
4.2.1 Liquid temperature
Pumped liquids must remain within certain temperature limits
•
with EPDM seals (standard versions): from -30°C to +120°C
•
with VITON/FKM seals (special versions): from -10°C to +120°C
4.2.2 Ambient temperature and altitude
In the case of ambient temperatures higher than +40°C, or the installation of the pump
at an altitude higher than 1,000 metres, the motor must not work at full capacity to
avoid the risk of overheating. Excessive ambient temperatures and low air density
reduce the motor's ability to cool down. In these cases, it may be necessary to use
a motor with a higher rated power. Below is a non-binding chart of motor capacity
percentage based on altitude or temperature (see Fig. 6/A).
4.2.3 Maximum number of motor start-ups
The table shows the maximum number of start-ups per hour for the electric pumps
supplied with a standard motor.
