As the name suggests, a submersible pump, also known as an electrical submersible pump, is a water pump that is completely submerged in the water and can be used for a variety of applications. The electric motor used in the process is hermetically sealed and also close-coupled to the pump. One of the major advantages of a submersible pump is that it does not require priming because it has already been submerged in the liquid.
Such pumps are also highly efficient and do not require you to spend energy on moving the water inside the pump. Certain submersible pumps can handle solids well, while others are only effective with liquids. These are quiet as they are underwater, and also, since there is no spike in pressure with the water flowing through the pump, cavitation is never a problem. Now that the basics are clear, let’s learn more about the submersible pump working principle.
