WARNING: the air supply pressure must never be over 7 bar or below 2 bar
WARNING: when using the pump with aggressive or toxic liquids or with liquids that may
represent a health hazard you must install suitable protection on the pump to contain, collect and
signal any spills: DANGER OF POLLUTION, CONTAMINATION, INJURIES AND/OR DEATH.
WARNING: the pump must not be used with fluids that arc not compatible with its construction
materials or in a place containing incompatible fluids
WARNING: 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
WARNING: 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
WARNING: 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, respect of the maximum temperature marked cannot be guaranteed
WARNING: 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
WARNING: 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
