A Submersible Pump (or sub pump, electric submersible pump(ESp)) is a device which has a hermetically sealed motor close-couped 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. Submerssible pumps push fluid to the surface as opposed to jet pumps having to pull fluids. Submersibles are most efficient than jet pumps.
Applications: They 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 pond filiters. Multiple stage submersible pumps are typically lowered down a borehole and most typically used for residential, commercial, municipal and industrial water extraction (abstraction), water wells and in oil wells.
Other uses for submersible pumps include sewage treatment plants, seawater handling, fire fighting (since it is flame retardant cable), water well and deep well drilling, offshore drillings rigs, artificial lifts, mine dewatering, and irrigation systems. Special attention to the type to the type of submersible pump is required when using certain types of liquids. Pumps used for combustible liquids or for water that may be containminated with combustible liquids must be designed not to ignite the liquid or vapors.
