    Deep well pumps are those in which the jet is located at the bottom of the well. The maximum depth for deep well pumps is determined by the inside diameter of and the velocity through the jet. The major advantage of jet pumps for deep well installations is the ability to situate all mechanical parts (e.g., electric/petrol motor, rotating ...

    en.wikipedia.org/wiki/Submersible_pump

    A submersible pump cable is a specialized product to be used for a submersible pump in a deep well, or in similarly harsh conditions. The cable needed for this type of application must be durable and reliable, as the installation location and environment can be extremely restrictive as well as hostile.

  4. Water well pump - Wikipedia

    en.wikipedia.org/wiki/Water_well_pump

    Deep well pumps extract groundwater from subterranean aquifers, offering a reliable source of water independent of municipal networks. These pumps, often submersible and powered by electricity, can access water reserves located much deeper than shallow wells, ensuring a consistent supply even during periods of drought.

    BWR Type 3 (BWR-3, BWR/3): Introduced in 1965, 800 MW (Dresden 2–3). [5] First use of internal jet pumps (single nozzle, 10 per loop, 20 total). 2 recirculation loops, variable speed recirculation pumps (one pump per loop, each pump had a rated flow of 45,200 US gallons per minute (2.85 m 3 /s)). Improved ECCS spray and flood, improved ...

  6. Completion (oil and gas wells) - Wikipedia

    en.wikipedia.org/wiki/Completion_(oil_and_gas_wells)

    Gas lift well: gas is fed into valves installed in mandrels in the tubing strip. The hydrostatic head is lowered and the fluid is gas lifted to the surface. Single-well alternate completions: in this instance there is a well with two zones. In order to produce from both the zones are isolated with packers.

  7. Airlift pump - Wikipedia

    en.wikipedia.org/wiki/Airlift_pump

    (The compressor is on the surface and no mechanical parts are needed in the well). However airlift wells must be much deeper than the water table to allow for submergence. Air is generally pumped at least as deep under the water as the water is to be lifted. (If the water table is 50 ft below, the air should be pumped 100 feet deep).
