Centrifugal pumps

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Radial-flow pumps specially adapted for elastic fluids, e.g. centrifugal pumps; Helico-centrifugal pumps specially adapted for elastic fluids > Centrifugal pumps

CPC:

Radial-flow pumps, e.g. centrifugal pumps; Helico-centrifugal pumps (F04D21/00 takes precedence) > Centrifugal pumps

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
