A submersible pump (or electric submersible pump (ESP)) is a device which has a
hermetically sealedmotor close-coupled to the pump body. The type is normally a centrifugal, but positive displacement pumps (such as
progressive cavity pumps) are also available. The whole assembly is submerged in the fluid to be pumped. This type of pump has become increasingly popular, particularly in the
water industry and industry in general for the pumping of water and wastewater, in
boreholes and
water wells, and in
artificial lift stations for pumping crude oil in the oil and gas industry. Small ESPs are widely used for household duties such as dewatering flooded cellars and basements. In the building and mineral industries they are used to pump slurries and sludges.
The main advantages of ESPs include:
No inlet pipework, valves or instrumentation.
Elimination of the associated costs and below-ground hazards of dry well structures in
pumping stations.
Exposure of the body of the pump to the pumped fluid possibly causing corrosion, contamination (of the pumped fluid) and maintenance issues (e.g. sewage and rags adhering to the outside of the pump, lifting chains and cable).
Higher initial capital cost for an ESP compared to a "standard" centrifugal pump.
I don't think true electric submersible pumps are used in aquariums, which are normally only litres in capacity, I think this should be changed to ponds and lakes

Maybe the "use" section should be expanded. AFAIK the two examples I gave in the section title here are only a very small tip of a huge iceberg. Limiting it to oil wells seems to give a wrong impression. Lisa4edit

MICC is a distinct type of cable that is different to other types of cable. Submersible pumps though make demands on cable standards for waterproofing in excess of what's normally required, but this is just a high standard for cable performance, not a fundamentally different type. We can't cover MICC or tinsel in an article on 6242Y, but submersible pump cables could sit perfectly well under an article on NYY cable, whether it's to be submerged or not, whether it's for use with pumps or not.
