SAFETY WARNINGS FOR PERSONS AND
EQUIPMENT
These symbols
words: "Danger" and "Warning", indicate the potential
risk deriving from failure to observe the safety precautions
to which they have been associated, as specified below.
Danger Warms that failure to comply with

Risk of electric
electric shock.
shock
Danger Warns that failure to comply with the
safety precaution may result in
damage to person and/or equipment.
Warning Warns that failure to comply with the
safety precautions may result in
damage to the pump or the plant.
GUARANTEE
We will repear under guarantee, eventual failures of sold
products. This is valid only:
1) If the failure is due to manufacturing blemish,
machining or material defect.
2) If failure is communicated to the firm or to one of its
representatives within the guarantee period of the product.
3) If the product is used exclusively under the conditions
described in the instructions for the control and
maintenance and according to expected uses.
4) If control systems incorporated into the product are
rightly connected.
5) If all repair and maintenance works are carried out in
workshops with semi-skilled personnel.
6) If are used original spare HEAD parts. So the guarantee
doesn't cover failures
maintenance, wrong installation, possible repear works
wrongly executed or normal wear.
We doesn't take upon itself any responsibility as about
possible damages caused to persons and/or things or for
economic loss, with the exception of what has been
previously declared.
HANDLING
Warning Use the special lifting eyebolt on the
head of the pump for the handling of
the unpacked unit.
Danger Do not use the electrical cable to lift
the pump.

shock

WORKING LIMITS

Warning - Maximum temperature of pumped
liquid 40 °C.
- The density of the pumped liquid
must not exceed 1200 Kg/m
together with relative
caused from insufficient
3
.
- The size of suspended solids present
in the pumped liquid must not exceed
the free passage through the impeller.
- Minimum liquid level: the pump
may work continuously at full load as
long as the liquid level does not drop
below the midpoint of the stator
housing.
With cooling jacket: the pump may
work continuously at full load, with
dry installation, or with diffuser
completely submerged.
- Immersion depth: maximum 20m.
- The electric pumps cannot be used
for heads below the lowest point in
the characteristic curve show in the
catalogue. Lower heads result in the
motor overload.
Danger The electric pumps must not be used
in environments where there is a risk
of explosions, or for the pumping of
flammable liquids.
NOISE
Not applicable because the pump works submerged in
wells.
By dry version: inferior to 70 db(A).

APPLICATIONS

This series of submersible pumps has been designed for
the pumping of waste water in industrial and civil
installations, pumping of mud and of light agricultural
sewage.
They are available in the following versions:

with lowering device: the electric pump unit
connects automatically with the coupling foot,
which is fitted with two guide tubes to assist the
lowering inside the pit;

with support foot: coupling for flexible tube,
handle and supporting foot.
INSTALLATION
SAFETY REGULATIONS
To avoid the risk of accidents during pump maintenance or
installation, the following regulations should be observed:
Danger - Never work alone. Use safety belt
and rope and also a gas mask, if
necessary. Do not overlook the risk
of drowning.
- Make sure that sufficient oxygen is
available and toxic fumes are present.
- Before welding or using electrical
equipment make sure there are no
risks of explosion.
