1. GENERAL
Read this documentation
carefully before
installation.
Installation, electrical connection and commissioning
must be carried out by skilled personnel in
compliance with the general and local safety
regulations in force in the country of installation of the
product. Failure to comply with these instructions not
only causes risk to personal safety and damage to
the equipment, but invalidates every right to
assistance under guarantee.
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.
