Graco 312877C important safety instructions Fluid Temperature Range, Diaphragm/Ball/Seat Material

Technical Data

Fluid Temperature Range

NOTICE

Temperature limits are based on mechanical stress only. Certain chemicals will further limit the fluid temperature range. Stay within the temperature range of the most-restricted wetted component. Operating at a fluid temperature that is too high or too low for the components of your pump may cause equipment damage.
