What is a Water Garden Pump?

A water garden pump that pushes waterfall or fountain water for oxygenation or just plain looks, needs to have constant water flow above the surface of the water. For this reason a properly chosen water garden pump needs to be chosen to send water above its surface. In the days of Pompeii, before 79 AD when a volcano froze this legendary roman city in time, plumbing was used in all parts of the cities life. Displacing water from one place to another requires momentum, and a pump does this in a practical way, through calculations such as head, pressure, flow and voltage, the proper kind of electrical pump can be chosen. Alternative water garden pumps could use diverse creative do it yourself sustainable projects such as solar or aeolic renewable energy sources, a half adapted siphon system using gravity or even as creative as a ram pump system with a rain barrel harvesting concept that uses collected rain water for waterfall energy production, ideas for sustainable water pumps are diverse.
The origin of the word pump is long lost in etymological history, but obviously the sound of the word Pompeii, translated into water pipe, or conduit in Latin. Modern Dutch inventors were thinking of this when they started using the word “pompe”. Historians know little, but the fact that energy efficiency is the key in any water pump has held true for more than 2,000 years, even before the first aqueduct started carrying water from the mountains into Rome. Moving water with gravity has been known since Archimedes’ Principle first stated; “the impulsion force is equal to the weight of volume of liquid displaced by the body.” In this case gravity was the energy moving water downhill… but a water garden needs it to move uphill, hence the use of pump.
Pumps take water from the water garden and push it uphill in the desired fashion, be that in the form of a majestic water fountain or meditative Japanese waterfall. Normally pushing water out of the aquatic environment is done in order to oxygenate it. This helps keep it in equilibrium with itself such as in the case of the submersed air pump at the bottom of a pond that just does the job of blowing bubbles up to the surface as in aquariums. Electrical pumps are chosen based on the head (height) of the desired point above the water’s surface level and flow pressure. Depending on the energy efficiency of the pump being used and the decision of whether it is to be an underwater pump or external pump will reflect in how much power it consumes (also known as voltage). Power consumption on a monthly $$ basis can really undermine a water gardeners hopes for having a cute water garden in the living room. But as buying an electrical water pump is the most common project solution for water gardens of all sizes, from aquarium pump to submersible pond pump, sustainable energy buffs refer back to renewable energy for capping that monthly $$ basis.
Electric solar water garden pumps work just like any grid driven pump, but usually have their very own photovoltaic or photosynthetic solar power panel rigged up in a discrete place on the side of a statue ornament or something even more creative. Aeolic pumps can be driven in the same manner, but usually work directly on a mechanical energy basis, too much energy dispersion seems to go on when dealing with magnets and electrical fields. Ram pumps use a constant flow of water from somewhere to do a similar job as this, and instead of using wind or solar energy, would use rain water reserve from a cistern, perhaps from the roof of the gardeners, house… In very large water gardens, a sustainable pump system might actually integrate all three systems, who knows?
Water garden pumps are used to both oxygenate with flowing air as well as flowing water and create beautiful effects in the garden such as bubbles (air pumps), waterfalls (water pumps) and fountains (water pumps). If the waterfall is very tall and uses a lot of water, then the pump must be stronger, the same goes for the water fountain if it is to have lots of pressure, they can be located subtly underwater, or hidden away in a pump house externally, size will determine this factor mostly. Water garden pumps are essentially mechanical, making them source quite diverse, from household and city grid energy, solar, aeolic, cistern harvesting, to plain old gravity.
