Air lift pump - Kihou Pump (English name) Bubble pump; air lift pump

Japanese: 気泡ポンプ - きほうポンプ（英語表記）bubble pump; air lift pump

Also called an air lift pump or air lift. A pump that uses the difference in specific gravity between the water outside the pipe and the air that is lighter than water by blowing compressed air into the bottom of the pipe and creating a mixture. Although compressed air is required, it has the advantage of having no mechanical moving parts and being less likely to break down. Disadvantages include low efficiency, the need to submerge the pipe deeply, and susceptibility to water pressure pulsations. Some pumps use inert gas as the gas and are used for lifting oil.

Japanese:

空気揚水ポンプ，エアリフトともいう。揚水管の一部を水中に入れて，その下端に圧縮空気を吹込み，水よりも軽い混合物をつくり，揚水管外の水との比重差を利用して揚水するポンプ。圧縮空気を必要とするが，機械的な可動部分がなくて故障のおそれが少い利点がある。欠点は効率が低いこと，揚水管を深く水没させる必要があること，水圧脈動の影響を受けやすいことなどである。気体として不活性ガスを用い揚油用に用いるものもある。
