How to say "pump" in Japanese

Choosing the right word
  • ポンプJLPT N1approx.Common
    nounCovers the noun: the pump as a device or piece of equipment, such as a water pump. Use it when English 'pump' names the machine rather than the action of pumping.
    ポンプはちゃんと動うごかなかった。↗
    The pump didn't work properly.
  • 汲むくむJLPT N2approx.Common
    godan verb, transitive verbMatches 'pump' as a verb in the sense of drawing water up; its basic meanings are to ladle, dip up, or scoop up liquid, so it describes the act of taking water, not the device.
    彼かれは井戸いどへ行いって水みずをくんできた。↗
    He fetched some water from the well.

Use 「ポンプ」 for the noun — the pump as a device — and 「汲む」 for the verb when pumping means drawing or scooping up water; 「汲む」 also covers ladling and dipping, so it is broader than pumping alone.
