This should be in Wikipedia:WikiProject Engineering rather than energy, in the Chemical Process Design & Engineering section, under pumps.Turner chris1 (talk) 13:11, 26 June 2013 (UTC)[reply]

Introduction

I intend to replace the intro text with the text below unless I receive comments.Turner chris1 (talk) 14:22, 25 June 2013 (UTC)[reply]

A submersible pump (or electric submersible pump (ESP)) is a device which has a hermetically sealed motor 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.
Cooling of the pump by the surrounding fluid.
Noise control.
Fewer NPSH and cavitation problems.

Disadvantages include:

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.

Looks like an improvement. Andy Dingley (talk) 13:07, 26 June 2013 (UTC)[reply]

Use in ponds and aquariums

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 Turner chris1 (talk) 11:05, 25 June 2013 (UTC).[reply]

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. Lisa4edit76.97.245.5 (talk) 17:20, 7 January 2009 (UTC)[reply]

Merge of Submersible pump cable

Insufficient independent notability for the cable article. Andy Dingley (talk) 10:18, 17 September 2012 (UTC)[reply]

I disagree on the grounds that submersible pumps have become a field of study unto themselves in today's world of regulations. I would love to know more about their cables, Submersible pump seal systems, Submersible pump motors, Submersible pump coolers, Submersible pump hand pumps, etc. I have added another reference to improve notabilty.

I too have to disagree with the proposed merge. The subject of submersible pump cabling might not be of interest to everyone, but the same can be said for the numerous other articles with cover all sorts of other wiring and cabling. Examples: Category:Electrical wiring, Category:Signal cables, Tinsel wire, Mineral-insulated copper-clad cable, Twin-lead, Ribbon cable, etc. --Tothwolf (talk) 18:18, 30 November 2012 (UTC)[reply]

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.
