Sometimes pumps, such as beam pumps and electrical submersible pumps (ESPs), are used to bring the oil to the surface these are known as artificial lift mechanisms.

16. Pumps and wells to improve water coverage in rural areas

After the necessary commercial contracts had been drawn up, ITT refused to allow its products to be sold to Acueducto Sur.

An aspirator, is a type of ejector jet pump, that produces vacuum by means of the Venturi effect.

Impoverished farmers should receive a free package of seeds, fertilizers, and low cost equipment (such as pumps for irrigation).

The Victorians understood this concept, and in the United Kingdom they built pumping stations with water pumps, powered by steam engines to accomplish this task.

For maintenance or replacement, submersible pumps are raised by a chain off of the duckfoot and up the two guide rails to the maintenance (normally ground) level.

There were rural infrastructure projects designed to produce labour savings for women, for example, by replacing hand drawing of water with boreholes and pumps.

Power of shape here's a whale. We've seen that the fins of this whale have tubercles on them. And those little bumps actually increase efficiency in, for instance, the edge of an airplane increase efficiency by about 32 percent.

So, on the top, we had these beautiful rainforests and an ocean, and underneath we had all this technosphere, we called it, which is where all the pumps and the valves and the water tanks and the air handlers, and all of that.

Still, the agency experienced other infrastructural problems, such as damaged pumps and broken water lines, which caused water outages and pressure problems throughout the island.

Pipelines which move petroleum products from places like Houston to areas of the east coast have had their flows interrupted because power outages shut down the pumps that kept materials flowing.

UNOCI has collaborated with United Nations agencies and ICRC on several projects to increase the number of functioning pumps, particularly in the north, and to establish water purification and distribution systems.

Features may include controls for fully automatic operation a high level alarm indication, in the event of pump failure and possibly a guide rail auto coupling pedestal system, to permit easy removal of pumps for maintenance.

In this configuration pumps are installed below ground level on the base of the dry well so that their inlets are below water level on pump start, priming the pump and also maximising the available NPSH.
