1.1. Pump description (example):
2. APPLICATIONS
Single-stage standardized centrifugal 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.
3. 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.

If a fuse trips which protects a three-phase motor, it is recommended to change the
other two fuses as well, not only the one that is burnt-out.
5. 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.
