Hazardous Substances
ACHTUNG !
The operating company bears the responsibility for the use of the WOB-L
®
Piston
Pumps.
Hazardous substances in the gases to be pumped can cause personal injuries and
property damage. Pay attention to the warning notices for handling hazardous sub-
stances.
The local regulations apply in foreign countries.
Combustible, aggressive and explosive Gases
Don’t pump combustible, especially aggressive or explosive gases or vapors or operate this
pump in an atmosphere containing combustible or explosive gases or vapors.
Examine before switching on whether that can form gas combustible gas/air mixtures which
can be promoted! Consider the regulations of the guideline 1999/92/EC.
The WOB-L
®
Piston Pumps are not certified according to ATEX guidelines
2014/34/EU
.
The WOB-L® piston pumps are not recommended for pumping acidic, basic or organic va-
pors.
Poisonous Gases
Use a
condensate
separator
(eg. Woulff bottle)
when pumping poisonous or harmful gases.
Prevent such substances from leaking out of the appliance or pump. Treat these
substances according to the applicable environmental protection regulations.
Test the strength and leak-tightness of the connecting lines and the connected apparatus.
Prevent environmental poisons, e.g. mercury, getting into the pumps.
Fulfil the requirements, for example:
German Hazardous Substances Regulation (GefStoffV) of 01. December 2010
Regulation
2016/1179/EU
(
c
lassification,
p
ackaging and
l
abelling
of hazardous substances),
Manufacturer's safety data sheets on hazardous substances.
2.5
High Temperatures
The WOB-L
®
Piston Pumps may heat up as a result of the temperature of the gas being
pumped and through compression heat.
Prevent the following maximum permissible temperatures from being exceeded.
+ 40 °C for the environment, and
+ 60 °C for the gas to be pumped.
The electric motor has a thermal overload protection.
