A Sewage Submersible Dewatering Pump (or sub pump, Electric Submersible Pump) 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, a problem associated with a high elevation difference between pump and the fluid surface.

Sewage Submersible Dewatering Pump push fluid to the surface as opposed to jet pumps having to pull fluids. Submersibles are more efficient than jet pumps


Sewage Submersible Dewatering Pumps are used in applications, including sewage treatment plants, seawater handling, groundwater pumping, fire fighting (since it is flame retardant cable), borehole drilling and pumping, water well and deep well drilling, offshore drilling rigs, artificial lifts, mine dewatering, irrigation systems, and water supply systems.

Special attention is required when using certain types of liquids. Pumps used for combustible liquids or for water that may be contaminated with combustible liquids must be designed not to ignite the liquid or vapors.

Use in Oil Wells

Sewage Submersible Dewatering Pumps are used in oil production to provide a relatively efficient form of "artificial lift", able to operate across a broad range of flow rates and depths.

By decreasing the pressure at the bottom of the well (by lowering bottomhole flowing pressure, or increasing drawdown), significantly more oil can be produced from the well when compared with natural production. The pumps are typically electrically powered and referred to as Electrical Submersible Pumps.
