3.2 Conforming Utilization
TRIVAC
®
T pumps can pump gases and vapours, and evacuate vessels or
vacuum systems in the fine vacuum range.
The pumps are suited for pumping water vapour within the specified water va-
pour tolerance limits. Avoid vapours that can condense into liquids when being
compressed inside the pump, if these substances exceed the vapour tolerance
of the pump. In the case of wet processes we recommend the installation of
liquid separators upstream and downstream of the pump as well as the use of
the gas ballast.
3.2.1 Non-conforming Utilization
The TRIVAC
®
T is NOT suited for pumping of:
■ radioactive and toxic substances
■ pyrophorous and explosive substances or gases
■ corrosive gases
■ oxygen (or other highly reactive gases) at concentrations exceeding
that of the atmosphere (> 21 % for oxygen).
Pumping of dust or much contaminated media
The pumps are not suited for pumping of liquids or media which carry
large quantities of dust. Corresponding protection devices need to be pro-
vided.
The standard pump is not suited for pumping of hazardous gases or va-
pours.
When cleaning a system in which a TRIVAC
®
pump has been integrated,
all parts in contact with the medium need to be compatible with the clean-
ing agent so as to prevent a chemical reaction. Residues of the cleaning
agent within the pump must be avoided.
