The document outlines electrical submersible pumps (ESP), including their main components of motor, seal, and pump. It describes the motor parts of stator and rotor, types of seals, causes of seal failure, how centrifugal pumps work by spinning fluid within an impeller and diffuser, and sizes of pumps manufactured by Alkhorayef Company. It concludes with an overview of the functions of the motor, seal, and pump in ESP systems.
23. What are the most causes of seal failure ?
• Bad selection
• Leakage
• Down & Up thrust
• Impurities ( foreign particles )
• Vibration
24. Pump
• Submersible pumps Lifts the fluid through the tubing to the surface.They
are a multi-staged centrifugal pumps. Each stage consists of a rotating
impeller and stationary diffuser.
25. Pump
• A Centrifugal Pump is a machine that moves fluid by spinning it
within a rotating impeller.
The impeller has a central inlet and a tangential outlet and
rotates inside a stationery diffuser
26. Pump
The impellers rotate with the shaft and spin at the RPM of the motor.
Pumps are assembled by stacking stages on a shaft and compressing the
stack in a housing.
A stage will produce a given amount of flow and lift (head) at the motor
RPM.
27. Pump
• The Impeller change the fluid
velocity through a number of vanes.
• This motion causes a vacuum area
to be created which draws more
fluid into the impeller.
28. Pump
The diffuser turns the fluids
kinetic energy into a potential
energy while passing to the next
stage.
29. Pump Sizes in Alkhorayef Company

• 513 SER 5.13DIA 1000 SER 10.00 DIA
• 538 SER 5.38DIA 1100 SER 11.00 DIA

30. FactoryTour
In five days , I’ve learned:
Motor stages of manufacturing as well as how to collect seal and pump
equipment. Finally I’ve got an idea about service equipment and how to repair
it.
31. Conclusion
Equipment Function
Motor Transfer electrical energy to mechanical energy to
move the shat to enable the pump to do its duty
Seal Protect the motor , mechanical connector and
provide an extra area for motor fluids
Pump Suck the oil from the well and lift it to the surface
by tubing.
