Asynchronous threephase submersible electric motor with squirrel cage rotor, class F insulation (max. 155°C / 310°F), IP68 protection degree according

to IEC 529 standards or IP58 according to EN 60034-5 standards, designed for continuous or intermittent service. The values pertaining to intermittent

service S3 are not supplied for this series of submersible motors. This is because the model equipped with cooling jacket must be installed if the motor

is liable to become uncovered during operation.

The power draw indicated on the data plate is slightly higher than the value given in the technical documentation supplied by Caprari as it also

accounts for the differences created by mass production of the electric pump.

The tolerance values established by standard IEC 34.1 (CEI - EN 60034-1) are valid for all the electric pumps. The hydraulic performances are

established by ISO 9906 cl.II standards.

The data measured may also differ owing to inaccuracies in the measuring instruments used for checking and/or to electricity mains with

characteristics (voltage/frequency/unbalances) differing from those indicated.

It is essential to comply with the minimum head value to ensure the motor is correctly cooled.

cooling jacket (please always check NPSH) (see indication on page 115).

When the electric pump is installed according to the instructions given in this manual and in compliance with the diagrams, the acoustic pressure

measured according to ISO 3746 standards and the gauging points, 2006/42/UE, were 1 m from the reference surface of the machine and 1.6 m from

ground or access platform level.

FORBIDDEN USES

To ensure correct and completely safe operation, never exceed the characteristics listed in paragraph 10 or the maximum performance characteristics

given on the electric pump data plate.

SAFETY REGULATIONS

Only specialized technicians equipped with adequate tools and fully familiar with the instructions in this manual may be allowed to work on the electric

pump.

Always comply with the rules of hygiene, accident prevention and safety provisions when installing a new pump or during maintenance operations, and

comply with the local provisions and regulations in order to prevent accidents. The purchaser shall be responsible for compliance with these safety

provisions and instructions.

contaminated equipment or liquids.

1.2. - The technicians working with the pumps must be vaccinated against the possible illnesses that could be caught following injury, contact or inhalation.

1.3. - Before proceeding with any work on the pumping station, check that all electrical cables entering the tank are disconnected from their relative

power supplies.

- that anyone lowered into the tank is equipped with safety harness;

- that there is always a worker outside the tank (never ever work alone even in optimum conditions) able to immediately act on the harness lifting ropes;

- that the area is adequately restricted by barriers and signs;

preventing goggles, rubber gauntlets, mask and a waterproof apron when carrying out these operations.

any operation;

- if the electric pump is dismantled, always wear work gloves when handling the parts;

- the temperature of the external surface of the motor can exceed 80°C. Take the necessary precautions to avoid burns.
