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. (EN 60335-1 : 02)
2. APPLICATIONS
Multistage centrifugal pumps indicated for booster
sets for water systems of small, medium and large
utilieties. They may be used in various fields of
applications such as:
 for fire-fighting and washing systems,
 for supplying drinking water and feeding
autoclaves,
 for feeding boilers and circulating hot water,
 for conditioning and chilling systems,
 for circulating and industrial processing plants.
3. PUMPED FLUIDS
The machine has been designed and built for
pumping water, free from explosive substances and
solid particles or fibres, with a density of 1000 kg/m³
and a kinematic viscosity of 1 mm²/s, and chemically
non-aggressive liquids.
Small quantities of sand, up to 50 ppm, are
accepted.
