Specification of

Submersible pump (ESP) is a device that has a tightly closed motor or combined with a pump body. All components are immersed in the liquid / water to be pumped. The main advantage of this type of submersible pump is that it prevents pump cavitation, a problem related to the high elevation difference between the pump and the liquid surface. Submersible pumps push liquids to the surface as opposed to jetpumps to draw liquid. Submersibles are more efficient than jetpump.

A submersible pump pushes water to the surface by converting rotary energy into kinetic energy into pressure energy. This is done by water being pulled into the pump: first in the intake, where the impeller rotation pushes water through the diffuser. From there, he headed to the surface.

The main advantage for submersible pumps is that it must never be considered, because it has been submerged in liquid. Submersible pumps are also very efficient because they don't really have to spend a lot of energy moving water into the pump. Water pressure pushes water into a submersible pump, thus "saving" a lot of pump energy.

In addition, while the pump itself is not versatile, of course the choice. Some submersible pumps can easily handle solids, while some are better only for liquids. Submersible pumps are calm, because they are underwater, and cavitation is never a problem, because there is no "surge" pressure when water flows through the pump.
