Use of Water Garden Pumps

Pond pumps are also called fountain pumps or water garden pumps, and serve four primary purposes:

  1. Pond filters– A pond filtration system removes toxins from water and keeps it clean and safe to use as water passes through it. It in the process maintains a clean and pleasant smelling pond.
  2. Circulation-Pond water has to be circulated to maintain healthy aquatic life by preventing water stagnation. You, in fact, need to install a pond water pump to your pond even if you don’t have a waterfall or fountain in it to keep the water moving.

Moving water oxygenates the water to help reduce algae growth. It also prevents mosquitoes from laying eggs on the water surface by mimicking natural water flow in the pond. It also distributes nutrients around the water to fish, plants and other aquatic creatures in it.

  1. Aerator-Pond air pumps prove useful where the water needs only oxygenation and not any water flow like during pond winterization. The pump provides a constant stream of oxygen and gas exchange in the water without any flowing water that only makes the pond water colder.
  2. With water features– You need a water fountain pumps to provide flowing water to water features like waterfalls, pond fountains or statutory fountains which circulate, aerate and may also filter your pond water.

Types Of Garden Water Pumps

There are various types of pond pumps, divided into two main categories:

Submersible pumps:

This is a better pump for smaller ponds or with water features needing less than 4,000 gallons of water per hour (GPH). These units are entirely installed under water, generally in the pond’s deepest part, and its unobtrusiveness is its significant benefit. Besides, it also runs without much noise as it’s underwater. It doesn’t spoil the pond’s look and is also easy to install as long as its cord length is long enough.

Its disadvantage is that it needs removal from the pond for cleaning and maintenance reasons. They cost more to operate when compared to external fountain pumps, and as some have oil, it may be risky for your fish or plants if there’s an oil leak. It’s also not useful for bigger ponds exceeding 5,000 gallons.

External pond pumps:

External pond pumps are better for large and medium-sized ponds, and as its name suggests, it’s installed outside the water. They can handle large water flows ranging from 4,000 to 10,000 GPH and are cheaper to use.

Its other advantages are that external fountain pumps are easy to maintain, have a longer life as they operate in dry conditions and it’s easy to replace parts as they are not resin-encased like submersible pumps.

However, they are disadvantageous as they take more time and effort to install, are quite noisy in function, have to be covered and are more expensive than submersible pond pumps.

Water fountain pumps are also divided into two, based on the type of drive the pump uses:

Magnetic drive pumps:

Magnetic drive pumps are oil-free and safe to use in ponds with fishes. They instead use an electromagnetic field to power the pump’s impeller. An electric charge generates a magnetic force on the impeller which has a magnet.

The magnet in turn moves, and makes the impeller cycle around. The pumps are thus energy efficient, and though it may be a bit expensive when compared to direct drive models, they make up for the expense with it’s reduced energy consumption.

They are also the quietest of all types of submersible, garden and fountain water pumps and are the easiest to repair.  However, they are not meant to be used with high head water features like fountains as they can’t generate enough force to pump water so high vertically.

Direct drive pumps:

Direct drive pumps are a better choice for powering fountains and waterfalls as they can reach higher heights. They are however cheaper than mag-drive pumps and are self-priming enough to draw water to them.

However, their dependence on only electricity makes this pump a bit more expensive to operate. Some models also contain oil that’s harmful to pond animals and plants if it leaks. The pumps are also generally sealed, making it difficult to maintain and repair the pump.

Pumps For Ponds are Further Divided into:

Air pumps

Air pond pumps do not generate water flow but instead only draw air to the pump and diffuse it into small bubbles. They are perfect for pond winterization as they oxygenate the water and exchange gases without creating any water flow.

Solar powered water fountain pumps

Solar powered garden water pumps are environmentally friendly and cost-effective and work as efficiently as their powered competitors. There’s no need to plug the pump into a power source, and you save money in the long run as it’s powered 100% off grid.

It is perfect to use in remote locations where power sources are a rarity. The better solar water pump for fountains even switches off at night once its solar charge is used up, so there’s no worry about noises at night.

However, all this is possible only if the panel is rightly positioned to get as much direct sunlight as possible. Its low power capacity also makes it a better choice for smaller ponds, but its initial purchase and setup costs are more than mains powered pumps.

And as the pump’s power and operation depend on sunlight, it may lie dormant in some regions during winter months. Not recommended for ponds needing more filtration like Koi ponds as the pump doesn’t work at night.

In-line pumps

These are external pumps located outside the pond. These pumps suck and feed water using the help of a hose running between the outer pump and pond.

Tips For Choosing The Right Pond Pumps

These are the various features to take into consideration while selecting the right water garden pump for your pond.


Safety is an important feature, so make sure you have the right hardware to install and use the pump safely. It should be powered by an outdoor power outlet with a Ground Fault Interrupter (GFI) connected to it. GFI is commonly seen on bathroom outlets as they break the circuit if and when water comes in contact with an electrical device.

The pump should also be at a suitable distance from the pond. While 6 feet is desirable, a distance of 10 feet is even better as it ensures the outlet doesn’t meet water when you work on the pump or filters.

Water quantity

Garden water pumps are categorized based on the amount of water they can move at a time, which is measured as GPH or gallons per hour. It defines how much water the pump can lift to a specified height in an hour. The approximate height to which the water is carried is called ‘head height,’ and maximum GPH attained is at zero head.

The head height is the average distance the water travels both horizontally and vertically from the pump to the top of the waterfall. While vertical distance is calculated using a ratio of 1:1, the horizontal distance is calculated using a ratio of 10:1.

So if the water fountain pump’s horizontal distance from the waterfall is 40 feet, its head height is 4 feet. And if its vertical reach to the top of the waterfall is 9 feet, it means it has a head height of 9 feet.

So the total head height here is 13 feet. The GPH tends to reduce as the head height increases. This is why waterfall pumps come with flowcharts displaying the GPH at increasing head heights.

Solar pumps are only used to power pond fountains as they are not that powerful. The pump’s power is measured in horsepower, which the manufacturer provides through charts to help you decide which unit is best for your pond.

Above water or submerged

You have to decide if you want to install your pond pump above or in water as both has it’s advantages and disadvantages. Pumps installed above water are easier to maintain and have fewer chances of underwater pollutants like sand and plant matter hampering its performance. However, these units are expensive and noisy.

Submersible pumps are favorites in small ponds where they are placed directly in water and work silently. However, there’s the hassle of pulling them out of the water to repair it and the risk of the pump breaking down without your knowledge. Besides, they are exposed to water contaminants.

There are two types of submersible pumps; pumps that work with magnetic engines which are better than the older ones that run on oil and coolant. This is because any failure in its working can lead to the oil and coolant ending up in water, to interfere with oxygen exchange and end up poisonous to underwater life.

Magnetic drives don’t have this drawback which is why they are a popular choice. They are also simple in design, where there are minimal chances of anything going wrong with the devices.

Size of pond

The pond size is essential in making your pump choice as too small a pump for a pond only leads to poor circulation and stagnant regions in the water. This in turn leads to low oxygen levels, poor water quality, and sludge accumulation.

Calculate the size of the pond by multiplying its length by the width and average depth, with 7.5 to find out how many gallons of water it holds. You can accordingly determine the right sized water garden pump that can circulate that the pond’s volume of water at least once every two hours or every hour if you have more fish in the water.


You are to choose your garden water pump based on its anticipated usage like if you plan to use it for filtration purposes or as a water features pump. If it’s expected to power a waterfall, find out how long, tall and broad the waterfall is. The cascading water here hits the pond surface to generate lots of bubbles and oxygen.

If you plan to use it as a water pump for fountains to create a fountain, it has to pump water through a fountainhead to create a pleasing display. The water fountain pump thus adds substantial oxygen to the pond as all the propelled water falls back down and breaks the pond surface. It’s also possible to use filter pumps to perform both tasks by pushing water up a filter which then returns via a waterfall after filtration.

Presence and type of aquatic life

Make your selection based on the fish or plant life living in your pond. This is important as some pond pumps are not safe for use in ponds with aquatic life. You also have to decide based on the type of fish you will be hoarding in the water. For example, if you have Koi fish in your pond, you need a larger pump with better and maximum filtration abilities to provide for maximum oxygenation that keeps your fish healthy.

Pump Specifications

Your garden water pump choice is best made based on the pump specifications. For example, decide based on the size of hoses the pump needs, it’s cord length and if it has the best pre-filter solution for protecting your pump.

Dynamic head pressure

This is the back pressure the pump faces while forcing water through its pipe to reach your waterfall, filter or stream. Factors affecting it are waterfall height, length, and diameter of the pipe where every 10 feet adds one inch of head dynamic pressure. Even the number of fittings like elbow and ball valves existing in the pipe affects the pressure as every 90° elbow and reducing fitting used adds an inch to the head dynamic pressure.

Width of waterfall

The pump should provide the right flow to give the perfect waterfall look. No point using a small pond pump for a waterfall as it only trickles water over the rocks and will not create a gushing flow of water.

Large garden water pumps are a better choice. You can make your choice by making calculations based on the look you want to achieve and the waterfall width. The general rule of thumb water circulated at the rate of100 GPH per inch of waterfall width creates a trickle, 150 GPH per inch creates a medium flow while 200 GPH per inch provides a steady stream of water for the waterfall.

So measuring your waterfall width in inches and multiplying it with these numbers help decide the power of the pump needed to create the look you want.

Operating costs

Most people don’t keep this in mind while determining the pump’s rates. You will be using pumps 24 hours a day except in winter. So if you have old direct drives, it’s better to buy a new one as the old pump consumes more electricity, and increases your electricity expenses.


It’s apparently better to buy a fountain pump with a more extended warranty as it means the manufacturer backs the product, and that the pump will give you years of dependable service.


The water garden pump should preferably have two filters. One is the prefilter which keeps the pump running smoothly by cleaning the water, without affecting water clarity or your fish health. It needs cleaning when there’s a noticeable drop in the pump’s water flow.

The second primary filter is usually a bio-filter that’s incorporated in a waterfall or stream. It breaks down fish waste to keep the pond safe and water clean. It should be run 24 hours a day if the water is 50 degrees hot as all it takes is a few hours of power disruption to kill the good bacteria in the bio-filter. These filters need an annual cleaning in the late fall or early spring when they have more bacteria.

Some pumps have pressurized filters, ideal for small and medium ponds. They are placed partially underground near the water and efficiently supplies water to the pond. Most filters can be connected to a backflush or drainage hose to backflush the filter for improved efficiency.

UV clarifiers or ultraviolet clarifiers help tackle the problem of green water as algae are too small to get trapped by filters and just pass through the filtration system. The UV clarifier uses UV radiation to clump together microscopic algae which are then trapped in the filter’s pre filter or bio-filter. It also helps kill harmful pathogens in the water.


So it’s proven that water fountain pumps are an essential addition to your water body, be it a pond, stream or aquarium. It keeps the water clean with its filtration system that filters large dirt particles and most also have UV clarifiers that prevent the formation of mold that makes the water green.

And as there are so many kinds and brands of garden water pumps available, you need to make an informed choice while buying one. The buying guide above and the many pond pump reviews below should prove helpful in making the right decision.
