** Pumps with Acetal fluid sections are certified:
II 2 GD
Ex h IIC 66°...135°C Gb
Ex h IIIC T135°C Db
ATEX T-code rating is dependent on the temperature
of the fluid being pumped. Fluid temperature is limited
by the materials of the pump interior wetted parts.
See Technical Data for the maximum fluid operating
temperature for your specific pump model.
