OPERATING MANUAL
VERSION 12/2012 ORDER NUMBER DOC 2330426
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
In some working conditions, the pump can be particularly noisy: for example when the
air feeding pressure 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.
Make sure the materials employed in manufacturing the pump are chemically compatible
with the uid to be pumped. A wrong choice can cause harming people (as a result of
prosection of noxious and irritant products) as well as polluting the environment, besides
prematurely damaging the pump and its hoses.
To quickly stop the unit in case of emergency, close the air cuto valve or the pressure
regulator; to interrupt the air supply to the pump’s motor. Cuto valve is not supplied with
the pump. It has to be provided and properly installed by the user.
Caution: delivery circuits of pneumatic pumps can remain pressurized, even when the air
input 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 periodically check
for presence of deposits as well as its cleanliness, the state of wear of the components and
proper operation of the pump assembly.
The operation has to be carried out in conformity with what is written in this manual.
4.2.7 EXPLOSION HAZARD
Do not ever use chloride or halogenated solvents (such as trichlorothane and methylene
chloride) with units containing aluminum or galvanized and zinc-plated parts. As 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.
