What is Submersible Pump?
A submersible pump is a mechanical equipment that works by pushing the water toward the surface instead of pulling it. It has a hermetically sealed motor connected to the pump body that helps to push the fluid toward the surface. It is a most famous type of the centrifugal pump. A submersible pump mainly uses to pump the water from the wells. This type of pump pushes water toward the surface by changing the rotatory motion (speed) into kinetic energy, and diffuser blades further convert this K.E into pressure energy.
The significant benefit of this pump is that it can prevent the pump from cavitation – these pumps are known as submersible pumps because these submerge entirely in the water. Therefore, the principal purpose of these pumps is to pump water out of the tanks, wells, or other vessels by submerging into the water or other fluids. These pumps also use in hot water-heavy oil applications where pressurized liquid from the ground is used to power a hydraulic motor in wells instead of an electric motor.
In 1928, Armais Arutunoff discovered 1st submersible pump. He was an engineer in the Armenian oil transportation system. The design of this pump was determined by Pleuger Pumps in 1929. Typically, this pump doesn’t require priming because it completely submerges in the fluid. However, this high-quality pump creates complexity and cannot function properly without problems, so it is never taken out of the water. These pumps are a good choice in many situations as they prevent cavitation in the pump. There are many applications of submersible pumps in different industries. For example, single-stage submersible pumps use for industrial, sewage, and drainage purposes, and multi-stage pumps are preferred for industrial, commercial, municipal, and residential purposes.
