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"
submercible 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.
