Hazardous Substances
The operating company bears the responsibility for the use of the diaphragm pump.
Hazardous substances in the gases to be pumped can cause personal injuries and property
damage. Pay attention to the warning notices for handling hazardous substances.
The local regulations apply in foreign countries.
Combustible Gases
The user must assess the process in accordance with Directive 1999/92/EC (ATEX 137) for
the extraction of explosive gas/air mixtures inside or outside a similar environment. In accor-
dance with the requirements indicated by this assessment, a suitable device must be se-
lected which fulfils the specifications of Directive
2014/34/EU
.
Aggressive gases
The MPC series is designed for extracting aggressive gases.
Please ensure that the substances used and/or arising are compatible with the stability of the
pump materials that come into contact with the gases.
Poisonous gases
Use a separator 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 escaping.
Fulfil the requirements, for example:
German Hazardous Substances Regulation (GefStoffV) of 01. December 2010
Regulations

High Temperatures
The diaphragm pump 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
.
Pumps with motors in Ex design do not have an overload protection switch. The user must
install them permanently in the terminal box in the course of protective measures complying
with the currently valid regulations.
