4. Introduction of pump
 Pump is a machine or mechanic equipment which is required to lift
liquid from low level to high level or to flow liquid from low
pressure area to high pressure area

8. Submersible Pump(ESP)
 In 1928 Russian engineer and inventor
Armais Arutunoff successfully installed
the first submersible oil pump.
 In the mid 1960s the first fully submersible
deep well water was installed.

9. Submersible Pump(ESP) cont.…….
 A submersible pump or electric submersible pump (ESP) is a
device which has a hermetically sealed motor close-coupled to the
pump body. The whole assembly is submerged in the fluid to be
pumped.
 A submersible pump is a pump that is able to be placed underwater
and still carry out its intended purpose.
 A submersible water pump pushes water to the surface, instead of
sucking the water out of the ground.

11. Working principle
 Electrical submersible pumps (ESPs), much like vertical
turbine pumps in design, are typically used to pump liquid.
Essentially, an electric motor drives the pump, and the fluid's kinetic
energy is increased. This energy is then partly converted into
pressure, which lifts the fluid through the pump.
 In video you will clearly see the working principle of ESP

12. Applications
 Submersible pumps are found in many
applications.
 Single stage pumps are used for drainage,
sewage pumping, general industrial
pumping and slurry pumping.
 They are also popular with aquarium
filters.
 Multiple stage submersible pumps are
typically lowered down a borehole and
used for water abstraction, water wells
and in oil wells.

13. Advantages
 It is used in very deep wells where a long
shaft is not practical.
 Unaffected by deviations in vertical
alignment of well.
 More efficient than jet pumps.
 It can be used in wells of diameter as
small as 15cm.
 It is less noisy.

14. Disadvantages
 The largest disadvantage of these pumps is that
you put it in the water. This means it will have a
shorter life because it is sitting in and sucking up
muck from your pond. It is also harder to clean
and maintenance because it is sitting on the
bottom of the pond.
 There is the chance the pump will become
corroded and lose its seals, thus allowing liquid
to penetrate into the motor housing and causing
substantial damage to the unit.
