CPV code 42124230 designates Parts of rotary positive-displacement pumps in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
42124230 is a leaf code — the most specific level of its branch — so it can be used directly as the main CPV code of a contract notice. If it does not quite fit, check the neighbouring codes under 42124200 (Parts of pumps or liquid elevators).
