1.

GENERAL

Read this documentation carefully before installation. It contains fundamental instructions to be followed during installation, operation and
maintenance.
The pump may be installed in either horizontal or vertical position, as long as the motor is always above the pump.
2.

APPLICATIONS

Multistage centrifugal pumps particularly suitable for constructing booster sets to supply water for small, medium and large users. They may be
used in various fields of applications such as:
•
for supplying drinking water and feeding autoclaves;
•
for sprinkling and irrigation systems;
•
for fire-fighting and washing systems;
•
for conveying condensate and cooling water;
•
for feeding boilers and circulating hot water (see "Liquid temperature range");
•
for conditioning and chilling systems (see "Liquid temperature range");
•
for water treatment plants;
•
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.
