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.
ENGLISH
The appliance is not intendend for use by persons

(including children) with reduced physical, sensory or
17
mental
capabilities,
17
knowledge, unless they have been given supervision or
17
instruction concerning use of the appliance by a person
17
responsable for their safety. Children should be
18
supervised to ensure that they do not play with the
18
appliance.

1.1 Safety
20
Use is allowed only if the electric system is in
20
possession of safety precautions in accordance with the
20
regulations in force in the country where the product is
21
installed (for Italy CEI 64/2).
1.2 Responsibility
21
The Manufacturer does not vouch for correct
21
operation of the machine or for any damage that it
21
may cause if it has been tampered with, modified
21
and/or run outside the recommended work range or
22
in contrast with other indications given in this
22
manual.

2. PUMPED FLUIDS
22
The machine has been designed and built for pumping
22
water, free from explosive substances and solid
23
particles or fibres, with a density of 1000 kg/m³ and a
kinematic viscosity of 1 mm²/s, and chemically non-
aggressive liquids.
Small sand impurities of 50 gr./m³ - Ø 1 mm are
accepted.
3. TECHNICAL DATA
3.1 Pump and motor group
The electric pump is a centrifugal multistage pump with
submersible motor and built-in non return valve,
designed to minimize friction losses.
The impellers are dinamically balanced and the shafts
are driven by co-axial bush bearings. The electric pump
is manufactured in two versions, radial flow and mixed
flow.
The radial version features compact axial stages made
of stage casing, impeller and diffuser, allowing the
assembling of a large number of stages to reach higher
delivery heads.
The mixed flow stages features instead stage casings
with built-in diffusers and semi-axial impellers. This kind
of pump is employed in place of radial versions when
higher capacities are required with the same well
diameter.
