Submersible Pumps

As well as the more common pressure pumps you will frequently see submersible pumps at your local supplier . . . . . So what’s the difference?


Submersible pumps

Characteristics of Submersible Pumps:

Most domestic submersible pumps come with an attached float switch which switches the pump on when the water level rises, and off before it runs dry.

  • They’re Quiet  The surrounding water absorbs any noise.
  • Don’t Need Priming  As the pump sits under the water it doesn’t need to be primed, which also improves efficiency.
  • Rarely Block These are centrifugal pumps, which can pass reasonably large solid particles.
  • Pump From Bottom of Tank/Well Useful  for emptying things, but bad if you need the best water quality (The worst water is typically at the bottom of a tank see: Understanding Tank Water Quality)


Best for transferring water in constant flow rate applications such as:

  • Emptying tanks
  • In a sump to keep basements dry
  • Pumping Storm Water
  • Pumping Grey Water
  • Irrigation systems (make sure there is a filter smaller than any nozzles)


Make sure you get the correct size pump, see: Pump Size
