A submersible pump is a device that operates while fully submerged in the fluid it pumps. Learn how it works and when to use one.
A submersible pump is a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation — a problem associated with a high elevation difference between pump and the fluid surface.
Submersible pumps push fluid to the surface as opposed to jet pumps which create a vacuum and rely on atmospheric pressure. They are used in many applications including drainage, sewage pumping, general industrial pumping, and slurry pumping.

How It Works:
When electricity is supplied to the motor, the motor drives the impeller. The impeller rotates and creates centrifugal force, pushing water from the inlet (bottom) upward through the discharge outlet. The hermetic seal prevents water from entering the motor housing.
