9.0 CHEMICAL COMPATIBILITY TABLE
Dosing pumps are widely used for dosing chemical products. It is
important to select the most suitable material for the liquid to be
dosed. The CHEMICAL COMPATIBILITY TABLE is a precious aid to
that end.
The following Table must be used as an indicative instrument.
Modifications in the transported fluid composition or particular service
conditions can reduce the resistance of the materials.
