415, Rotary Kinetic Fluid Motors or Pumps, appropriate subclasses for rotary fluid pumps.

416, Fluid Reaction Surfaces (i.e., Impellers), appropriate subclasses for specific features of fluid pump impellers. 417, Pumps, appropriate subclasses for subject matter relating to the pumping of fluids. Class 417 takes subject matter relating to the pumping of slurries, fluent material and the like if handled in a manner not inconsistent with the handling of fluids.
