Submersible Turbine Pump And Its Advantages & Disadvantages

Submersible Turbine Pump

  • A submersible turbine pump is one in which the pump and the electric motor are placed below the water surface of a well. Delivery of water to the surface is through a riser pipe on which the assembly is suspended.
  • The characteristics of the pump unit are similar to a conventional vertical turbine pump.
  • They have been used in wells over 4000 meter deep. Units with more than 250 stages have been used.
 Submersible Turbine Pump


  • It eliminates the long vertical shaft from the ground surface to the pump which reduces bearing friction and provides an unobstructed pipe for delivery of water to the surface.
  • It can be used where the installation is flooded or where an above ground pump house would be inconvenient, unsightly or hazardous.


  • Operating parts are inaccessible and difficult to inspect.
