Submersible Pump | Applications & Working

Submersible Pump

  • Each submersible pump means a device that becomes a hermetically (airtight) sealed motor close-coupled into the pump body.
  • That whole assembly is submerged into the fluid to be pumped.
  • The significant main advantage of this type of pump means that it prevents pump cavitation, some problems compared with some high elevation differences within the pump also the fluid surface.
  • Submersible pumps push fluid upon the surface as opposed to jet pumps having to pull fluids. Submersibles mean higher efficiency than jet pumps.

Working Principle 

  • Electric submersible pumps continue multistage centrifugal pumps operating in a vertical position.
  • Liquids, accelerated with the impeller, lose their kinetic energy into the diffuser anywhere a conversion of kinetic through pressure energy takes place.
  • This is a unique main operational mechanism of radial also mixed flow pumps.
  • This pump shaft does connect to some gas separator or this protector with some mechanical coupling about this bottom from the pump.
  • Fluids enter the pump through an intake screen also lifted by the pump stages.
  • Different parts include some radial bearings (bushings) distributed along each length of every shaft providing radial support into the pump shaft.
  • An unforced thrust bearing takes up part of this axial force arising within the pump but most of those forces remain absorbed by this protector’s thrust bearing.


Submersible pumps exist found in many applications

  • Single-stage pumps remain used during drainage, sewage pumping, general industrial pumping including slurry pumping
  • Both mean are also popular including pond filters
  • Multiple-stage submersible pumps remain typically lowered down some borehole more most typically applied during a residential advertisement, municipal including industrial water extraction [abstraction] water wells further in oil wells.
  • Submersible pumps include sewage treatment plants, water well extremely deep good drilling, irrigation systems, firefighting {since that is flame retardant cable}, off-shore drilling rigs, artificial lifts, mine dewatering, also seawater handling.
  • Pumps in electrical hazardous locations used toward combustible liquids or toward the water that may mean contamination including combustible liquids must do designed not to ignite the liquid or vapours.
