APPLICATIONS
Single-stage stub shaft type centrifugal motor-driven pumps with a spiral body, dimensions in accordance with DIN 24255 -
EN 733 and flanged DIN 2533 (DIN 2532 per DN 200). Designed and built with advanced characteristics, they are
outstanding for their particular performances which ensure maximum yield while guaranteeing absolute reliability and sturdy
construction. They cover a wide range of applications, such as water supply, circulation of hot and cold water in heating, air-
conditioning and refrigerating systems, transfer of liquids in agriculture, market gardening and industry. Also suitable for use
in fire-fighting sets.

PUMPED FLUIDS
The machine has been designed and built for pumping clean, pure and aggressive fluids, on
condition that in the latter case the compatibility of the pump construction materials is checked
and that the motor used has sufficient power for the specific gravity and the viscosity of the
fluid.

MANAGEMENT
5.1.
Storage
All the pumps/electropumps must be stored indoors, in a dry, vibration-free and dust-free environment, possibly with constant
air humidity. They are supplied in their original packaging and must remain there until the time of installation, with the intake
and delivery mouths closed with the special adhesive disc supplied. In the case of long storage, or if the pump is stored after a
certain period of operation, only the parts made of low-percentage alloy materials, such as cast iron GG-25, GGG-40 which
have been wet with the pumped fluid, should be kept in the special preserving mediums available on the market.
5.2.
Transport
Avoid subjecting the products to needless jolts or collisions.
To lift and transport the unit, use lifting equipment and the pallet supplied
standard (if applicable).
Use suitable hemp or synthetic ropes only if the part can be easily slung, as
indicated in fig.5.2. If an eyebolt is provided on the motor, it must not be
used for lifting the whole assembly.
5.3.
Dimensions and weights
The adhesive label on the package indicates the total weight of the electropump. The dimensions are given on page 119/127.

WARNINGS
6.1.
Skilled technical personnel
It is advisable that installation be carried out by skilled personnel in possession of the technical
qualifications required by the specific legislation in force.
The term skilled personnel means persons whose training, experience and instruction, as well as their
knowledge of the respective standards and requirements for accident prevention and working conditions, have
been approved by the person in charge of plant safety, authorizing them to perform all the necessary activities,
during which they are able to recognize and avoid all dangers. (Definition for technical personnel IEC 364).
The appliance is not intendend for use by persons (including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsable for their safety. Children should be supervised to ensure
that they do not play with the appliance.
