A Submersible Pump has sealed motor, which is closely coupled to the pump body and pushes water to the surface. The whole assembly is underwater or submerged in the fluid that needs to be pumped. The primary advantage of this pump is the prevention from the pump cavitation, which occurs due to the rapid changes in the liquid pressure. The major areas where cavitation could occur is the pump, propeller and impellers.
As opposed to the jet pumps that pull the fluid, submersible pump push fluids to the surface. There are two types of submersible pumps:
- Submerged pump type with submersible motor
- Submerged pump with a dry motor, which is connected to the pump through a long shaft or tube
Submerged is always used for anything which is underwater. These submerged pumps are normally used for an uninterrupted water supply including fresh drinking water, irrigation and for various industrial applications. A Submersible pump can be connected to a riser pipe with a non-return valve, or it can be connected to a flexible hose. It has two versions known as single-stage and multi-stage, and multi-stage is most commonly used.
If the submersible pump and its motor are not installed correctly then overheating will damage the whole equipment.
