Translation guide
An impeller is a rotating component in a pump or compressor that moves fluid by centrifugal force. In Japanese, the term is primarily technical and used in engineering contexts.
The rotating part that transfers energy to a fluid, commonly found in pumps, turbines, and compressors.
The most common direct loanword from English, widely understood in technical and industrial settings.
The impeller of this pump is made of stainless steel.
A native Japanese term literally meaning 'blade wheel,' used in engineering and technical documents.
Please adjust the rotation speed of the impeller.
An alternative loanword spelling, less common than インペラ.
We changed the design of the impeller.
A rotating device used to stir or mix liquids, similar to an impeller in a washing machine or blender.
Both mean impeller, but インペラ is more common in spoken technical Japanese and product manuals, while 羽根車 appears in formal engineering documents and patents.
Do not use インペラ to refer to fan blades, propellers, or turbine blades in non-pump contexts. For fans, use ファンブレード; for propellers, use プロペラ.
