In the oil and gas industry, electric submersible pump (ESP) systems are probably best known as an effective artificial lift method of pumping production fluids to the surface.
What is oil submersible pump?
An oil-filled pump is defined as having the motor cavity filled with oil, usually to cover the upper bearing and windings. … This more efficient heat transfer method, versus a dry-mounted pump, results in a lower operating temperature for the motor and its internal components, and it helps extend the life of the motor.”
Which pumps used in oil and gas industry?
A centrifugal pump is the most common type of pump used in the oil & gas industry. It comprises one or more impellers, which move fluids by rotation and draw them into the suction end of the pump and then, through centrifugal force, push the fluid out from the discharge end.

What is the major disadvantage of submersible pumps?
There are a few disadvantages with submersible pumps, and two have to do with the seal. The seals can become corroded with time. When that happens, water seeps into the motor, rendering it useless until it is repaired. Also, that seal makes the submersible pump a bit difficult to get into for repairs.
How long can a submersible pump run dry?
