Emec VMS MF - Material and Chemical Compatibility

55
Solenoid driven metering pumps are widely used to dose chemical fluids and it is important that the most suitable material in
contact with fluid is selected for each application. This compatibility table serves as a useful help in this respect. All the informations
in this list are verified periodically and believed to be correct on the date of issuance. All the informations in this list are based
on manufacturer’s data and its own experience but since the resistance of any material depends by several factors this list is
supplied only as an initial guide, in no way EMEC makes warranties of any matter respect to the informations provided in this list.
