Chemical Compatibility guide
Attention:
All the information in this chart is only approximate and should only be used for an initial choice
of the type of materials best suited for the customers’ pumps. The data comes from various
highly reliable sources. Despite this, GemmeCotti itself did not carry out the relative tests, and is
not responsible for the preciseness of the data. Therefore, GemmeCotti takes no responsibility
for possible malfunctions or damages of any type caused by the incorrect selection of
construction materials and/or of the incorrect choice of pump size if it is not made by
GemmeCotti itself after having received all pertinent information regarding the application and
the characteristics of the pumped liquid.
