Submersible Borewell


"PEW" submersible pumps are vertical, multi stage, centrifugal pumps with motor at the bottom & pump at the top. The water enters at the bottom of the pump and flows upwards through many stages.
The stainless steel/bronze impellers rotate inside the diffusers with inherent guide vanes. The diffusers direct water leaving each impeller towards the suction opening of the next impeller. Such a flow through each stage of impeller and diffuser combination adds pressure at each stage and finally water under high pressure is discharged through outlet at the top.

FEATURES
  • Upper Housing, Lower Housing, Adaptor, Motor Base, suction and NRV are made of C.I. FG-220 Grade.
