Submersible Pumps

Submersible Pumps

A submersible pump (or electric submersible pump (ESP) is a device which has 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.

Submersible pumps are found in many applications. Single stage pumps are used for drainage, sewage pumping, general industrial pumping, and slurry pumping. They are also popular with aquarium filters. Multiple stage submersible pumps are typically lowered down a borehole and used for water abstraction or in water wells.
