3.1.3.2 Temperature limits of pump type FC
Depending on the design, different maximum pumping media temperatures are
permissible for pumps of the FC series.
If the pumping media temperatures are not specified in the documentation, the
lower value is permissible.

FPC pumps in which an occasional occurrence of explosive gas
atmospheres within the pump is permissible (category 2; IIB; EPL Gb /
Gc; additional marking on rating plate X), the following must be
observed:
- Explosive atmospheres within the pump with the temperature
class assignment T4, T5 and T6 are not permitted.
- The max. permissible pumping media temperature for the EPL
Gb / Gc; T1-T3 is T
