the pump. When shipping the contaminated pump for servicing,
please also state the type of hazard. For this you must use a form
which we have prepared for you.
7 When cleaning a system in which a TRIVAC pump has been integrat-
ed, all parts in contact with the medium need to be compatible with
the cleaning agent so as to prevent a chemical reaction. Residues of
the cleaning agent within the pump must be avoided.
8 Contaminated parts can be detrimental to health and environment.
Before beginning with any work, first find out whether any parts are
contaminated. Adhere to the relevant regulations and take the neces-
sary precautions when handling contaminated parts.
0.5 Danger of ignition
1 Only those pumps which are equipped with an ATEX certified motor
are suited for operation in the explosion hazard areas approved for the
pumps.
2 The standard version of the TRIVAC B is not suited for operation in
explosion hazard areas.
3 The TRIVAC pumps including the accessories are fundamentally not
suited for pumping of combustible and explosive gases or vapours.
The pump including accessories is only suited within the scope of the
ATEX guideline for pumping of explosive gases and vapours. Mixtures
of substances may, regarding the fire and explosion risk be critical or
uncritical. The operating company is under the commitment to analyse
this and rate the hazard potential accordingly so as to therefrom derive
the necessary safety measures which must be introduced.
4 Provided ignitable or pyrophorous substances are present in the
equipment you must:
■ ensure that no air can enter into the equipment,
■ ensure that the system is leak-tight,
■ with an inert gas purge (with dry nitrogen, for example) dilute all ignit-
able gases or vapours which may enter into the pump through the
pump’s inlet and/or with an inert gas purge reduce the concentration
of ignitable gases or vapours in the pump and in the exhaust line to
less than a quarter of the lower explosion limit (LEL) published for the
respective gases.
0.6 Hazard caused by noise
The noise level produced by the pump less than 60 dB(A). Suitable
hearing protection measures must be introduced.
