2. APPLICATIONS
18
Multistage centrifugal pumps indicated for booster
18
sets for water systems of small, medium and large
18
utilieties. They may be used in various fields of
18
applications such as:
18
for fire-fighting and washing systems,
18
for
18
supplying
18
autoclaves,
19
for feeding boilers and circulating hot water,
19
for conditioning and chilling systems,
19
for circulating and industrial processing plants.

3. PUMPED FLUIDS
19
The machine has been designed and built for
19
pumping water, free from explosive substances and
20
solid particles or fibres, with a density of 1000 kg/m³
20
and a kinematic viscosity of 1 mm²/s, and chemically
20
non-aggressive liquids.
21
Small quantities of sand, up to 50 ppm, are
21
accepted.
