Attention:

All the information in this chemical compatibility 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.
