According to the description, this 220V single-phase household submersible pump made of stainless steel has the characteristics of slender appearance, oil-filled motor cavity and leather bowl. However, the specific depth limit for entering water varies depending on the product design and manufacturer specifications, so it is impossible to accurately determine whether its working depth can reach 120 meters underwater.
Usually, the working depth of domestic deep well submersible pumps is relatively small, generally between 30 and 80 meters.
For greater power and professional use, submersible deep well pumps
can reach deeper underwater working depths. Therefore, you should consult the product manual of the specific submersible pump model or consult the manufacturer to understand its professional limits.operating inverter and its scope of application. This ensures that you choose the right submersible pump for your needs.
First we need to determine if it is pure water or water in the general sense?
If it is pure water, it is a poor conductor of water. At that point, if you put 220 V AC into the water, nothing will happen if it is water in the general sense, because it contains water; minerals, it is a conductor of electricity (but the resistance is very high), which generates heat. This is why we use wire or hacksaw blades to make our own "water heater" in winter.
