Note: Order the two stickers together.
Several liquids have a high expansion coe cient. In some cases its volume can rise with
consequent damage to hoses, ttings and cause uid leakage.
When the pump sucks liquid from a closed container, ensure that air or suitable gas can
enter the container to avoid a vacuum being generated in the container itself. Thus a
negative pressure is avoided. The vacuum could implode the container (squeeze) and can
cause it to break. The container would leak and the liquid would ow out.
The pressure ratio is 1:1. Therefore the pressure generated by the pump is equal to the
input air pressure.

4.2.8 NOISE RISK
4.2.9 MATERIAL CHEMICAL COMPATIBILITY
4.2.10 EMERGENCY STOP
4.2.11 TIGHTNESS CHECK
4.2.12 MAINTENANCE
Make sure that the pump's construction materials are chemically compatible with the uid
to be pumped. A wrong choice can cause harm to persons (as a result of the in uence of
harmful products and products which irritate skin) as well as polluting the environment,
along with premature damage to the pump and its hoses.
To quickly stop the unit in case of an emergency, close the air cut-o valve or the pressure
regulator to interrupt the air supply to the pump’s motor. The cut-o valve is not supplied
with the pump. It must be provided and properly installed by the user.
Caution: The pneumatic pumps' delivery circuits can remain pressurized, even when the air
cut-o valve is closed.
When using the pump after a long period of inactivity, check tightness of all parts subject
to pressure.
Depending on the type of use and the substances used, the user has to check for the
presence of deposits on the pump as well as check its cleanliness at regular intervals and
the state of wear of the components and proper operation of the pump assembly.
The operation must be carried out in conformity with what is written in this manual.
4.2.7 EXPLOSION HAZARD
Never use chloride or halogenated solvents (such as trichloroethane and methylene
chloride) with units containing aluminium or galvanized and zinc-plated parts. They may
react chemically thus producing an explosion danger.
Read the classi cation and information lea et concerning the product and solvent to be
used.
In some working conditions, the pump can be particularly noisy: for example when the
compressed air supply is high and when there is no pressure or a very low pressure in the
pumped uid (free ow operation). In these cases, all personnel working next to the pump
shall wear adequate individual protections and/or use valves and seats in plastic material,
provided the working conditions and the compatibility with the pumped uid allow it.

4.3.3 MAXIMUM SURFACE TEMPERATURE
4.3.4 MAXIMUM SURFACE TEMPERATURE EXOTHERMIC REACTIONS
4.3.5 CONNECTION PIPES
4.3.6 PUMP PROTECTION
Avoid running the pump sucking air (without uid inside). The air, combined with the
vapor of ammable uids, can generate internal areas with an explosion hazard.
Periodically check that the pump is working regularly, paying special attention to the
presence of air in the pumped uid, which may be caused by a breakage in the pump.
Avoid operating the pump with damaged diaphragms.
The maximum surface temperature of the pump depends on the temperature of the
pumped uid, that must not exceed the values indicated in the "Technical Data" chapter.
Fluids incompatible with the pump’s materials or particularly reactive mixtures of products
with several components may cause exothermic reactions and develop dangerous
temperatures or pressure.
Connection pipes must be made of conductive material and properly grounded.
If the pumping uids contain solid particles, install a lter on the intake circuit. This
prevents particles, that are large enough to damage the internal parts of the pump, from
entering. Refer to the Technical Data chapter to verify the maximum size of solids that can
be pumped.
Keep metal surfaces clean. Electric conductivity of the surfaces is essential for explosion
protection.
Frequently clean the equipment so as to prevent insulating substance residue from
accumulating.
Do not use rusted parts or metal tools that may cause sparks of a mechanical origin inside
the explosion hazard area.
