Fluid Temperature Range
* The maximum temperature listed is based on the ATEX standard for T4 temperature classification. If you are
operating in a non-explosive environment, FKM fluoroelastomer’s maximum fluid temperature in aluminum pumps is 320°F
(160°C).
NOTICE
Temperature limits are based on mechanical stress only. Certain chemicals will further limit the fluid operating tem-
perature 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.
