MAINTENANCE
Make sure that the pump's construction materials are chemically compatible with the fl uid
to be pumped. A wrong choice can cause harm to persons (as a result of the infl 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-off valve or the pressure
regulator to interrupt the air supply to the pump’s motor. The cut-off 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-off 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 classifi cation and information leafl 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 fl uid (free fl 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 fl uid allow it.
