Submersible pump is the name given to one of the pump types operating in the liquid or medium to be processed. The motor is mounted adjacent to the pump body. Since the submersible pump is in direct contact with the liquid, the motor is equipped according to some technical specifications. One of these technical features is its waterproof housing. It is also filled with oil that will prevent any liquid that may cause a short circuit from entering and protect it against damage. Thanks to submersible pump oil, leakage of liquid is prevented and possible dangers are prevented to a great extent. Connection points are designed to be air and watertight. We can say that one of the features that makes submersible pumps so useful and advantageous is that they are designed to operate without exposure to external factors.
