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.
