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.
