Important Safety Instructions
Read all warnings and instructions in this manual.
Save these instructions.
Refer to the Pump Matrix on page 23 to determine
the model number of your pump.
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.
