2. APPLICATIONS
16
Multistage centrifugal pumps indicated for booster
16
sets for water systems of small, medium and large
16
utilieties. They may be used in various fields of
16
applications such as:
16
 for fire-fighting and washing systems,
16
 for
16
supplying
16
autoclaves,
 for feeding boilers and circulating hot water,
16
 for conditioning and chilling systems,
16
17  for circulating and industrial processing plants.

3. PUMPED FLUIDS
17
The machine has been designed and built for
18
pumping water, free from explosive substances and
18
solid particles or fibres, with a density of 1000 kg/m³
18
and a kinematic viscosity of 1 mm²/s, and chemically
20
non-aggressive liquids.
20
Small quantities of sand, up to 50 ppm, are
20
accepted.
