the air supply pressure must never be over 7 bar or
below 2 bar.
when using the pump with aggressive or toxic liq-
uids or with liquids that may represent a health haz-
ard you must install suitable protection on the pump
to contain, collect and signal any spills: danger of
pollution, contamination, injuries and/or death.
the pump must not be used with fluids that are not
compatible with its construction materials or in a
place containing incompatible fluids.
installing the pumps without on-off valves on the
intake and delivery sides to intercept the product in
case of spillage is forbidden: danger of uncontrolled
product spillage.
installing the pumps without on-off, three-way or
check valves on the air supply piping to prevent the
pumped liquid from entering the pneumatic circuit if
the diaphragms are broken is forbidden: danger of
fluid entering the compressed air circuit and being
discharged into the environment.
should the user think that the temperature limits
set forth in this manual may be exceeded during
service, a protective device must be installed on the
system to prevent the maximum allowed process
temperature from being reached. If exceeded, re-
spect of the maximum temperature marked cannot
be guaranteed.
the pumps must always be grounded irrespective
of any organ to which they are connected. Lack of
grounding or incorrect grounding will cancel the
requirements for safety and protection against the
risk of explosion.
the use of pumps made with non-conductive
material, which become charged with static, and
without suitable grounding for flammable liquids
is forbidden: risk of explosions due to static charge.
aggressive, toxic or dangerous liquids may cause
serious injuries or damage to health, therefore it is
forbiffen to return a pump containing such products
to the manufacturer or to a service center. You must
empty the internal circuits from the product first and
wash and treat it.
pumps containing aluminium parts or components
coming into contact with the product cannot
be used to pump III-trichloroethane, methylene
chloride or solvents based on other halogenated
hydrocarbons: danger of an explosion caused by a
chemical reaction.
