Глубина всасывания насосов. Подробно с примерами. С какой глубины станция может поднять воду?

In this video, I'll use examples to explain the maximum suction depth of surface pumps (including pumping stations). This topic usually raises the most questions when choosing a pump, because on one hand, the instructions state that the pump can lift water from a depth of no more than 8 meters, while your neighbor, for example, says this isn't true and that his pump lifts from a much greater depth. In this video, I'll explain why my neighbor is wrong and what exactly he's doing wrong.
