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

 

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)

Uses

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)
