When the temperature limits are reduced because of internal materials selection, the
maximum allowable surface temperature T
temperature class, the same way as in case of D, dust protection.

For T5 (100°C) and T6 (85°C) classes and if ambient temperature exceeds the range
-20°C / +40°C contact your distributor.
1.6.3 II 2(G)D allowable temperature TG GS, GP, GM, H and SRT
The maximum surface temperature (T
T is determined as the lowest temperature derived from following equations:
max
• T = temperature limits of selected internal materials (i.e. pump selection).
max
• T = T
max
• T = 2/3 x T.

TG GS, GP, GM, can be used in a temperature range between -20ºC and +40ºC.
•
TG H in stainless steel execution can be used in a temperature range between -40ºC
and +40ºC; materials other than stainless steel can be used in the temperature range
between -20ºC and +40ºC.
