CAUTION:
risk of premature wear and/or diaphragm breakage.
It is forbidden to close or choke the sectioning valves of the product suction duct during pump operation.
Changing the general performance and head of the pump
and/or subjecting the diaphragms to strong stress affects their duration.
3.1.24
The components of the internal pneumatic circuit (including the shaft) are made of materials which are not
specifically resistant to chemicals and corrosive products; in the event of a rupture of the membranes, the
fluid may enter the internal pneumatic circuits and the environment and damage the components.
WARNING:
damage to the central insert.
If the diaphragms are ruptured and come into contact with corrosive fluids, the central insert and shaft
must be completely replaced.
3.1.25
The presence of dust and/or deposits on the external and internal surfaces of the pump can negatively
affect the process temperatures. In environments with a potentially explosive atmosphere, it can even
compromise safety and cancel the requirements envisaged by the affixed ATEX marking.
The pumps must not be installed and/or exposed to sand and/or pressurised abrasive material that could dam-
age the external plastic parts.
CAUTION
risk of overheating and/or fire
It is necessary to periodically verify the absence of dust and/or deposits from the external and internal sur-
faces of the pump and, if necessary, remove and clean with a damp cloth. It is forbidden to use the pump for
pumping powders and dehydrated and/or solid materials of any kind (flammable or not).
3.1.26
Disassembly of the compressed air supply/discharge pipes and fittings must be carried out in a dust-free
manner. Before disassembling, clean the outside of the pump to prevent deposits and impurities from
entering the air circuit.
CAUTION
: risk of damage to the central insert.
Before refitting the compressed air supply/discharge fittings and hoses to the pump, make sure that
there are no deposits of dirt or dust that could enter the pump's internal circuit.
3.1.27
In severe conditions, the pump can reach significant external temperatures (Max 70°C) during its intended
operation, in these cases it is necessary to provide a suitable guard and/or suitable marking to signal the
residual risk.
CAUTION
: risk of high temperatures and/or burns.
Before working on or coming into contact with the external surfaces of the pump, it is recommended to wait
for cooling and/or wear protective gloves.
3.1.28
Before disassembling the pump, always relieve the residual pressure in the internal pneumatic circuit as
described in
Section "5.2 PUMP SHUTDOWN"
.
CAUTION
: risk of internal back-pressures and projection of components during disassembly.
In abnormal conditions (incorrect installation and/or shutdown and/or standstill conditions), residual pressure,
which is not discharged, may be generated inside the pump. Before opening and disassembling the pump, it
is necessary to secure the pump casings with suitable ratchet straps.
3.1.29
Aggressive, toxic or dangerous fluids can cause serious physical injuries and/or dangerous harm to health.
Always flush and
empty the internal circuit of the product and wash and treat the pump before disassem-
bling, storing and/or shipping it to the manufacturer.
CAUTION
:
risk of injuries or harm to health.
It is forbidden to disassemble, store, and / or return the pump with residues of aggressive, toxic or dan-
gerous product, or not properly washed and decontaminated to the Manufacturer or a Service Centre.
Always complete and affix the flushing form
(see 5.1.4 PUMP FLUSHING FORM)
to the pump after
treatment and before dispatch; absence of the form or failure to complete it will result in NON-CON-
FORMITY in acceptance.
In addition to their primary function, the components of S
CUBIC and
S
BOXER
pumps are designed and
manufactured to fulfil important functions that affect the overall safety of the pump;
only use original
spare parts when replacing worn parts.
Failure to comply with the above may result in dangers for the Operator, Technicians, people, the
pump and/or the environment in which it is installed, for which the Manufacturer is not responsible.
