Table 3: Authorised operating conditions for the IL/DL/BL series
The use of solvents is not permissible since elastomers in the gaskets
might be corroded. In turn, this can lead to uncontrolled leakage.
5.3 Operation with flammable liquids
and explosion protection
Observe all relevant regulations when operating a pump with flammable liquids! These
include, in particular:
ƒ
Technical rules for operational safety (TRBS)
ƒ
Technical regulations for hazardous substances (TRGS)
ƒ
Guideline 2014/34/EU for equipment and safety systems intended for use in poten-
tially explosive atmospheres
ƒ
Machinery Directive (2006/42/EC)
ƒ
Industrial Safety Regulations (BetrSichV), in accordance with Guideline 2009/104/EU
ƒ
Explosion protection regulation (11th ProdSV), in accordance with Guideline
2014/34/EU
ƒ
Hazardous Substances Ordinance (GefStoffV)
The possibility of electrostatic charging of the fluid must be taken into ac-
count during utilisation of the pump, as is the case with all circulation pro-
cesses involving flammable liquids. Ignition hazards could arise as a result.
