METALLIC PUMPS can operate past 212°F (100°C). However, if you are
operating above these limits, consult the factory for assistance.
PLASTIC PUMPS can operate to the following temperature limits:
• ACETAL 32°F (0°C) to 220°F (104°C)
• POLYPROPYLENE 32°F (0°C) to 175°F (79°C)
• PVDF 10°F (-12°C) to 225°F (107°C)
NOTE: These are average temperatures. Chemicals and solvents can have an
effect on temperature limit
