Electric deep well submersible pumps are multistage centrifugal pumps operating in a vertical position, also Liquids, accelerated by the impeller and lose their kinetic energy in the diffuser where a conversion of kinetic to pressure energy takes place and This is the main operational mechanism of radial and mixed flow pumps.
Also submersible pumps shaft is connected to the gas separator or the protector by a mechanical coupling at the bottom of the pump and Fluids enter the pump through an intake screen and are lifted by the pump stages and other parts include the radial bearings (bushings) distributed along the length of the shaft providing radial support to the pump shaft, also An optional thrust bearing takes up part of the axial forces arising in the pump but most of those forces are absorbed by the protector’s thrust bearing.
