Submersible Pumps

To avoid any misunderstanding in choosing the pump, there two kind of submersible pumps:

• Single impeller for drainage and sewage water
• Close coupled multistage impeller for clean water.

Electric submersible pumps have a hermetically sealed motor close-coupled to the pump body. Insulation class F. Protection IP X8 or 68 depending on the pumptype.

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 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.
