3.1 SAFETY RULES
The Original Instructions must always be available to operators. Dangerous or hazardous practices or
practice not complying with the Safety Rules and with the recommendations contained herein, may cause
material damage, serious injuries and in extreme cases even death for which the Manufacturer cannot
be held responsible.
3.1.1
All pumps undergo functional tests and are tested with water at 20°C before being shipped to the Cus-
tomer, therefore, tap water residues can be found inside them.
CAUTION
:
risk of chemical reactions to water
Before installing the pump for use with liquids that react with tap water, it is necessary to open the product
circuit and dry all internal surfaces.
3.1.2
The personnel in charge of installing, inspecting and maintaining the pump must have suitable technical
preparation and knowledge of the product to be pumped and also have specialist knowledge on poten-
tially explosive atmosphere and related risk for uses in ATEX areas.
CAUTION
These instructions are essential for the compliance of the pump with the requirements of Directive 2014/34/EU
so they must be: available, known, understood and used by all Operators.
3.1.3
Use of the pumps in a manner that does not comply with the instructions indicated in the Manufacturer’s
use and maintenance manual will cancel all the requirements for safety and protection against of explo-
sions.
CAUTION
The maximum allowed temperature for process fluids (in zone 1 and zone 21) is equal to 65°C or 80°C
depending on the construction materials of the pump;
if exceeded, compliance with the affixed ATEX
marking is not ensured.
3.1.4
The air supply to the pump must always include the installation of a suitable non-return valve and the
pressure
must never be lower than 2 bar or higher than 8 bar. S

pumps are self-lubri-
cating (no further lubrication required); supply the pump with dry filtered air and DO NOT lubricate. It is
FORBIDDEN to feed the pump with lubricated, unfiltered and/or undried air.
CAUTION
: danger of fluid entering the compressed air circuit and being discharged into the environment.
It is forbidden to install the pump without a non-return valve on the air supply line to prevent the pumped fluid
from entering the pneumatic circuit in the event of a rupture of the diaphragms.
Even in battery installations,
the non-return valve must be installed on each pump.
3.1.5
The air in the pneumatic circuit must always be discharged in a free atmosphere, free of dust and satu-
rated vapours which could damage the internal circuit.
CAUTION:
danger of damage to the internal pneumatic circuit.
For installations with the pump submerged, or operation in environments with a harsh atmosphere (dust,
vapours or saturated vapours), provision must be made for the installation of air fittings and hoses (of
suitable materials), to take the air outlet point outside the working environment/liquid.
3.1.6
In pump installations with high delivery heads, very dense fluids with high specific weight and/or high
counter-pressures, freezing of the pneumatic circuit outlets may occur.
CAUTION
:
danger of air discharge freezing and loss of efficiency and/or pump shutdown.
Provide for the installation of a glycol adder on the air supply line, upstream of the pump.
3.1.7
Where the user presumes that the temperature limits set forth in this manual may be exceeded, a pro-
tective device must be installed on the system to prevent the maximum allowed temperature from being
reached.
ATTENTION:
danger of loss of conformity with the affixed ATEX marking.
It is forbidden to use the pump at temperatures higher than those permitted and specified in the manual;
if the
maximum temperature is exceeded, conformity with the marking is not guaranteed.
