WORKING LIMITS
Warning
- Maximum temperature of pumped liquid
(see pump data sheet).
- The density of the pumped liquid must
not exceed (see pump data sheet).
- 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 pump
data sheet. 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:
together with relative words:
Danger
The pump has been designed to be used with liquids that may be
hazardous to your health. To avoid injuries to your eyes or skin,
comply with the following safety precautions when operating on
the pump:
•
always use safety goggles and rubber gloves;
•
rinse the pump well with a hot water cleaning machine
before servicing it;
•
rinse the different components with clean water after
having disassembled them;
•
wrap a rag around the oil chamber screw whenever you
have to loosen it, to prevent sprays from reaching your
skin or eyes in the event that pressure has built up in
the pump due to infiltration of the pumped liquid.
In the event of contact with toxic chemicals, proceed as follows:
•
eyes: Rinse immediately with running water for 15
minutes keeping eyelids wide open. Contact an eye
doctor;
•
skin: Remove the contaminated clothing, wash skin
with soap and water; if necessary, consult a doctor.
FOLLOW ALL THE OTHER HYGIENIC AND SAFETY
PRACTICES AND LOCAL RULES AND REGULATIONS.
HOISTING EQUIPMENT
Suitable hoisting equipment is necessary for lifting the pump and
lowering it inside the well, if possible without requiring a take-
up.
The minimum distance between the lifting hook and the
trap/floor must be 0.8m to allow for the extraction of the pump
from the well.
Oversized hoisting equipment may cause damage to the pump in
the event that it should get jammed during the lifting operations.
Make sure that the lifting equipment is properly secured.
Danger
ELECTRICAL CONNECTIONS
The entire electric system must be installed by skilled personnel.
Follow local rules and regulations.

- 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.
- Do not overlook dangers to your health;
follow common hygienic practices.
- Be aware of risks resulting from
electrical malfunctions.
- Make sure that the hoisting equipment is
in good condition.
- Install a suitable barrier around the
working area.
- Make sure that a fast easy exit to the
open air is available.
- Use a helmet, safety goggles and
protective shoes.
- All the people working in sewage water
pumping stations must be vaccinated
against any diseases that
transmitted.
- Never introduce your fingers inside the
suction opening as there is a risk of
injuries due to contact with the impeller.
Keep in mind that the pump may stop and
restart
automatically
following
triggering of thermal protections or of
remote control devices; only the power
supply switch may eliminate this risk.
WARNING! Keep clear of suspended
loads.
If the cable must be replaced, for safety
reasons, the earth conductor (yellow-
green) must be about 50 mm longer than
the phase conductors.
