Engines for deep pumps can be water loading or oil loading .
A feature of the design of the deep pump is that the engine and the pump are combined into one and are used to pump and transport water, immersed in underground wells . since the engine is simultaneously plunged into water, there are many structural shapes, including a dry type, a half -dry type, an oil -filled type, a wet type (т.е. водопогруженный тип) и т. д. Кроме того, конструктивная форма погружных электронасосов для глубоководных скважин обычно включает маслопогружной трехфазный асинхронный двигатель, который предназначен для работы в жидкости, водонепроницаем и устойчив к коррозии. This shows that the engine of the deep pump can be immersed in water or oil, depending on the scenario of application and constructive requirements .
