(1) | This subclass covers non-positive-displacement pumps for liquids, for elastic fluids, or for liquids and elastic fluids whether rotary or not having pure rotation. |
|
(2) | This subclass does not cover combinations of non-positive-displacement pumps with other pumps, which are covered by subclass F 04 B, except that the use of such other pumps for priming or boosting non-positive-displacement is covered by this subclass. |
|
(3) | Attention is drawn to the Notes preceding class F 01, especially as regards the definition of "pump". |
