Please note that these are recommended standard values only which might vary depending on the specific application. I.e. the maximum allowable filtration temperature amongst others depends on filtration pressure, chemical composition of the slurry, cycle time, choice of materials etc.
Our qualified expert team will assist you anytime in determining the right materials for your specific application.
