WARNING: the use of dampeners for flammable liquids is forbidden if they are made of non-conductive materials that
charge statically (plastic materials) and without suitable grounding danger of explosion caused by static charges
WARNING: Aggressive, toxic or dangerous liquids may cause serious injuries or damage health, therefore it is forbidden
to return a dampener 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
WARNING: dampeners 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 explo-
sion caused by a chemical reaction
WARNING: the PDA dampeners cannot use with Acetylene, Hydrogen, Carbon disulfide
WARNING: the components of the pneumatic exchanger, including the shaft are made from materials that are not spe-
cifically resistant to chemical products. In case the diaphragm break, replace these elements completely if they have
come into contact with the product
WARNING: avoid using lubricated and/or un-dried air
WARNING: ascertain that no anomalous noises can be heard during operation. If they occur, stop the dampener imme-
diately
WARNING: ascertain that the fluid at the delivery side does not contain gas. Otherwise stop the dampener immediate

WARNING: periodic controls must be made to ensure that there is no powder and/or deposits on the external and inter-
nal surfaces of the dampener and, if necessary, clean them with a damp cloth
WARNING: removal of the air supply pipe must be done when free from powder. Before restarting the dampener, ensure
that no powder has entered the pneumatic distributor
To replace worn parts, use only original spare parts
However five general elements are important:
A- all the operations must be carried out by skilled personnel or monitored by qualified personal as appropriate
B- implement personal protection works (when the dampener is installed in places involving more than occasional visits)
against splashes of fluorescent fluid for accidental breakage and conveying works (always) of possible fluid leakages
towards collection tanks
C- wear acid-resistant clothing and protection whenever operating on the pump
D- make sure that the Intake and delivery valves are correctly closed during the disassembly
E- make sure that there is no supply to the pneumatic circuit during the disassembly
It should be noted that it is very important to realize systems with pipes well arranged, identifiable, suitably equipped
,with shut-off valves, with comfortable compartments and passages for operators who must inspect their status (since
the pressure developed by the pump may promote failures to the system if it is of defective construction or worn).
INSTALLATION AND START-UP PERSONNEL
Interventions allowed only to specialised personnel who may eventually delegate to others some operations depending
on specific evaluations (technical capability required: specialisation in industrial plumbing or electric systems as nee

ded).
MAINTENANCE AND OPERATIONAL PERSONNEL
Interventions allowed to general operators (after training on the correct use of the plant):
dampener starting and stopping
•
opening and closing of valves with the pump at rest
•
emptying and washing of the pump body via special valves and piping
•
cleaning of filtering elements
•
Interventions allowed to qualified personnel (technical capacities required: general knowledge of the mechanical, elec
