Submersible fish pond pumps are capable of producing a fixed amount of pressure (energy) that is used to pump water through the pond system, and in some cases to also lift water to the top of a waterfall. These two factors are closely related and are respectively known as Pond Pump Head and Pond Pump Flow. As each submersible garden pump can only produce a predetermined amount of energy then as a larger percentage is given to the flow then the amount of lift will reduce and vice versa. To be able to specify a pond-pump correctly you need to know how much water is to be pumped and to what height.

Submersible garden pumps can be purchased to operate:

  • Using mains power (110 – 240 volts) - The most common form for the vast majority of garden pond situations.
  • Using low voltage (12 or 24 volts) - Ideal for safety conscious environments where there are young children such as shopping malls.
  • As a solar powered pump - Only recommended in climates with lots of sunshine and as a back up pump. They can cause several problems within the garden pond, particularly if they are used to supply a biological pond filter.
