Become thoroughly familiar with the instructions in the documents consigned with the product. This will enable you to work in complete safety and to
obtain the best performance the product is able to offer.
The following instructions apply to the standard version of the electric pump operating in normal conditions. Special versions, shown by the product
code, may not fully comply with the instructions herein (when necessary, the manual will be supplemented with additional information).
As it is out policy to continually improve our products, the data in the documentation and the product itself may be subject to modi cation without the

GB
Failure to comply with the instructions in this manual, improper use of the pump or unauthorized modi cations to the product shall void all forms of
guarantee, while the manufacturer shall not be held responsible for any deriving damages to persons, animals or property.
Never allow the pump to operate dry as the bearings are lubricated by the pumped uid. The internal hydraulic part of versions HF
ATTENTION
and HV18÷50 in thermoplastic resin would be damaged.
Before working on the product in any way, always check that the electrical parts of the system on which work is to be carried out are
not connected to the electricity main.
The product described in this manual is designed for industrial purposes, use in aqueducts, for irrigation or similar. As such, it may only be handled,
installed, operated, serviced, repaired and dismantled by specialized personnel possessing the necessary quali cations and equipped with
adequate tools. Such personnel shall have previously become fully familiar with the contents of this manual and any other documentation supplied
with the product. Always comply with all the safety, accident-prevention and anti-pollution instructions in the manual during each individual operation,
together with all the more restrictive local provisions in force.
During operation, take care of the smooth spinning shaft in the stuf ng box zone. It could catch on clothing, long hair or other.
The motor and pump, when this operates with hot water, can reach surface temperatures which could scorch the skin. Take due care.
Do not use water for extinguishing purposes if the electrical equipment catches re.
For safety reasons and to ensure compliance with the warranty conditions, the purchaser must not use the pump should this become faulty or in the
event of a sudden variation in the performances of the pump itself. Installation must be such as to prevent contacts with the pump unit which could
represent a hazard for persons, animals and property. Inspection and servicing procedures must be organized in order to prevent all form of risk
should the pump unit malfunction.
Consult the "Handling and storage" chapter for safe handling and storage.
The electric pumps have one or more centrifugal impellers in series, turning in an clockwise direction (viewed from the delivery side). They are
directly coupled to special enclosed electric motors with IP55 protection degree or in an optional protected version, with protection degree IP23 (in
compliance with EN 60034-5 standards). They are available in a vertical version HV, to reduce the size of the installation, and in a horizontal version
HF, to optimize the suction capacity even at maximum ow rates. When the product is installed according to the instructions given in this manual
and in compliance with the diagrams, the acoustic pressure level issued by the machine reaches the cautionary values in dB(A) given in the table in
chapter 11 "Technical data, dimensions and weights".
In particular:
- the noise was measured according to ISO 3746;
- according to Directive 98/37/EC, the gauging points were 1 meter from the reference surface of the machine and 1.6 meters from ground or
access platform level;
- the maximum value is on the fan side of the electric motor;
- the values have a ± 3 dB(A) tolerance;
- the pump values were gauged at maximum ef ciency point;
- the motor values were gauged during no-load operation.
If requested, binding noise values may be supplied when the equipment is ordered.
The standard version of the product has been designed to pump clear water from accumulation tanks or to raise the pressure in boosters.
The standard product is not suitable for:
- dry operation;
- pumping uids other than clear water;
- pumping liquids containing a concentration of solids exceeding 0÷20 g/m
"Technical data, dimensions and weights");
- pumping liquids with a temperature exceeding 70÷90 °C (158÷194°F)(consult the "Operating limits" table in chapter 11 "Technical data,
dimensions and weights");
- pumping in ammable uids;
- operation in places liable to explosion hazards;
- closed valve operation for longer than 3÷6 minutes (consult the "Operating limits" table in chapter 11 "Technical data, dimensions and weights");
- operation with frequent stops/starts (consult the "Motor Table" in chapter 11 "Technical data, dimensions and weights");
- operation at altitudes exceeding 1000 m (may vary according to the installed electric motor);
- operation at ambient temperatures exceeding 40 °C (may vary according to the installed electric motor);
- at a suction pressure less than the required NPSH (consult the technical documentation of Caprari S.p.A.);
- at an operating pressure exceeding 13÷30 bar (consult the "Operating limits" table in chapter 11 "Technical data, dimensions and weights").
Remember to check that the product conforms with any pertinent local regulations.
