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 manufacturer makes warranties of any matter respect to the informations
provided in this list.
