It’s fairly stunning what one of these machines can do. The ones pictured above operate in different ways – the blue one sits in a dry place, all snug and warm and “pulls’ the water from somewhere, conducting it on through itself to another destination. The other onet sits in water and pumps the water straight out into a pipe for wherever it is destined. The one on the right is called a “submersible pump” and its role in landscaping has just exploded.
In landscaping, the “indoor” pump requires a dry setting- the same as any swimming pool pumps sits. It being electrical and not waterproofed per se, obviously it operates out of a room or constantly dry cavity, constructed solely for the purpose. The submersibles sit on the bottom of a water pool and function in what results in the same product – running water outward and almost always upward.
Here is a splendid look at two pumps in one water feature, both submersible and both performing separate functions:

What we see in this lower level of a water feature is a blue pump, dedicated to feeding a large pipe, routing the water far to the top and giving the waterfall its overall rate of flow. The smaller pump, as is evidenced by the rock through which a smaller, clear tube is inserted, is what landscapers call a “bubble rock”. These smaller features are for any number of purposes, from enriching the overall look of a water feature such as this one, to providing bubble rocks at anywhere in a landscape to create the sound and motion of water as well as to provide a diverting highlight, featuring the colors and structure of a pretty stone.
In the finished look below, we see the results of the two pumps, doing what they are designed for:
Often, we see smaller submersibles used in other bubble rock features as well.
Nor do “bubble rocks” simply need tiny pumps. Some are downright humongous:
Large waterfalls can be run by those water pumps driven by larger machines – even diesel engines, such as this one at Microsoft Campus in Seattle:
Whatever the effect desired, one can bet there is a pump designed for just that use. Any more, designs are based around the gallons needed, then the proper pump is ascertained. There is literally no limit on what is possible. The effects of this marvelous bit of machine insight has massive effects on landscaping and is very much the cause of the burgeoning installation of waterfalls and small water features now enhancing yards at homes all over the world.
