OPERATING MANUAL
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. So that a
negative pressure is avoided. The vacuum could implode the container (squeeze) and can
break. The container would leak and the liquid ow out.
The pressure ratio is 1:1. Therefore the pressure generated by the pump is equal to the
input air pressure.

OPERATING 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.
4.2.8 NOISE RISK
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.
4.2.9 MATERIAL CHEMICAL COMPATIBILITY
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.
4.2.10 EMERGENCY STOP
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.
4.2.11 TIGHTNESS CHECK
When using the pump after a long period of inactivity, check tightness of all parts subject
to pressure.
4.2.12 MAINTENANCE
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.

VERSION 12/2012ORDER NUMBER DOC 2330426
OPERATING MANUAL
4.3.2 OPERATION WITHOUT FLUID
Avoid running the pump sucking air, without uid inside. The air, combined with the
vapour of ammable uids, can generate internal areas with an explosion hazard.
Periodically check that the pump is working regularly, paying special attention to presence
of air in the pumped uid, which may be caused by a breakage in the pump.
Avoid operating the pump with damaged diaphragms.
4.3.3 MAXIMUM SURFACE TEMPERATURE
The maximum surface temperature of the pump depends on the temperature of the
pumped uid, that must not exceed the values indicated in the section "Technical Data".
4.3.4 MAXIMUM SURFACE TEMPERATURE EXOTHERMIC REACTIONS
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.
4.3.5 CONNECTION PIPES
Connection cables must be made of conductive material and properly grounded.
4.3.6 PUMP PROTECTION
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 paragraph Technical Data to verify the maximum size of solids that
can be pumped.
Keep the metal surfaces clean. Electric conductivity of the surfaces is essential for explosion
protection.
Frequently clean the equipment so as to prevent residue of insulating substances from
accumulating.
Do not use rusted parts or metal tools that may cause sparks of a mechanical origin inside
the explosion hazard area.
