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.

The appliance is not intendend for use by persons
17
(including children) with reduced physical, sensory or
17
mental capabilities, or lack of experience and
17
knowledge, unless they have been given supervision
17
or instruction concerning use of the appliance by a
17
person responsable for their safety. Children should

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

2. PUMPED FLUIDS
22
The machine has been designed and built for pumping
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 5-10 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.
