API is a standard defined by a standards committee in the USA - last definition in October 1994.
The standard is specified to represent quality features and standardisation for the petrochemical industry.
Version 675 is applicable to dosing pumps.
Only piston diaphragm dosing pumps and piston pumps are permissible, not diaphragm pumps.
The standard mainly describes process pumps for high system pressures, in particular with respect to materials, connections and tests.
Individual agreements are basically permissible between customer and manufacturer, since the standard is understood to be rather a guideline.
