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
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.
Explosive gases
The diaphragm pumps of the series MPC are certified according to ATEX guidelines
2014/34/EU, device category 3, valid for the gas contacting parts (interior) of the pump.
The diaphragm pumps of the series MP are not certified according to ATEX guidelines
2014/34/EU.
Aggressive gases
The MPC series is designed for extracting contaminated gases!
The use of diaphragm pumps of the series MP cannot be recommended for such cases of
application!
Especially aggressive gases have to be explicitly checked for material resistance as de-
scribed in chapter 3.6 and, if necessary, modified.
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, e.g. mercury, getting into the diaphragm pumps.
Fulfil the requirements, for example:
German Hazardous Substances Regulation (GefStoffV) of 01. December 2010
Regulation 2016/1179/EU
(Classification, Packaging and Labelling of hazardous substances),
Manufacturer's safety data sheets on hazardous substances.
2.5

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.
+ 40 °C for the environment, and
+ 60 °C for the gas to be pumped.
The motor for single phase alternating current is protected against overload by an integrated
motor protection switch.
