Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If rotary vane or gear displacement mechanism
Rotary positive displacement pumps have separate classification from reciprocating types.
If specifically designed as parts for internal combustion engines
Fuel injection pumps for engines are classified with engine parts in heading 8409.
If for medical applications like infusion therapy
Medical pumps for liquids, even reciprocating, fall under medical/surgical appliances.
