Submersible Pumps

As the name suggests, submersible pumps are designed to be fully submerged in liquid to be pumped. This is due to the pumps hermetically (water tight) sealed motor close-coupled to the pump body. The main advantage of this pump type is that it prevents pump cavitation, a problem associated with a high elevation difference between the pump and the fluid surface. Submersible pumps push fluid to the surface as opposed to self priming jet pumps having to lift and pull fluids.

Submersible pumps are found in many applications:
►Single stage pumps are used for drainage, sewage pumping, general industrial pumping and slurry pumping.
►Multistage submersible pumps are typically lowered down a well or borehole and used for water abstraction or rain water harvesting.
