Pump:
Multistage centrifugal pump with radial and mix flow impeller direct coupled to motor. The section intermediate is fitted with strainer. The stage casing are connected to each other with stud and nuts,in some model the casing are strapped with tie bar to ensure prefect sealing and to absorb the torque. The pump bearing are water lubricated and screened against the ingress of sand. The motor cables run alongside the pump and protected against mechanical damages by metallic cable sheaths.
Motor:
"Sabar" submersible motors are 2 pole squirrel cage induction motor has water lubricated bearings. It's winding lies in water and is therefore intensively cooled. The motor is protected against the entry of well water and sand etc. The excess pressure due to the heating up of the winding and water filled in is compensated by pressure equaling rubber diaphragm provided in the bottom most side of the motor. The axial thrust if the pump is taken care by titling thrust bearings which is designed for untoward thrust load. The pump shaft and motor shaft are rigidly connected sleeve type coupling.
