Submersible pond pumps run on a fairly basic principle when broken down. An electric motor is used to drive an impeller. As the impeller turns, water is drawn in one side of the pump, and is expelled out the other. … The larger the impeller, the more water can be pumped.

Do pond pumps need electricity?

Since these pumps are solar powered there is no need for mains electricity, so they can be installed anywhere around the pond.

Where do you put a pond pump?

The pump should be positioned at the bottom of the pond yet within easy reach for maintenance. A top tip is to attach cord or rope to the pump so it can be easily lifted out of the pond – never lift a pump by its electrical cable as this is dangerous.
