Having a pond inside your own garden will be very appealing, but it also requires a lot of work for maintenance. So with this you should choose the proper pump.
Pond pumps helps the circulation of water inside your pond furthermore it helps you to conserve water and good for your fish and plants.
If you want to get a good pump, there are several things to consider.
Your Pond’s Water Flow
Ideally, the flow should be half of your pond’s volume. For example, if you have 1,500 gallons of water in your pond, the flow should be at least 750 gallons per hour (GPH).
This may also varies in waterfalls. Let’s say your waterfall’s width is about 10 inches, then it would need to have at least 100-150 GPH per inch.
Having fish in your pond may also requires to increase the flow of water of your pond. In this scenario, the water flow must be doubled. So if you have 1,500 gallons of water in your pond, then 1,500 GPH should be flowing.
Thus one of the things to consider is how capable that pump could provide a good water flow inside your pond.
The Size Of Your Pond Pump
The performance of your pump may vary depending on the pressure and resistance it’s pushing against. The total dynamic head, which refers to the elements that add pressure to your pump such as piping, elevation and water flow, is an important factor to take into consideration.
The more pressure or resistance your pump meets, the stronger it needs to be. Basically, if you have a 2,000 GPH pump, it is maxed out at just 2,000 GPH. If your total dynamic head is high, you would need to have a bigger or higher-capacity pump.
To determine the ideal size of your pump, you should measure your pond’s total dynamic head. To do so, just follow this formula:
- If you have a waterfall, add one foot of head pressure for each foot of vertical lift.
- Add a foot of head pressure for each 10 feet hose or pipe.
- Add two feet of head pressure for each 90 degree fitting.
- Add a foot of head pressure for every other type of fitting.
Once you have the total feet of your head pressure determined, you’ll be able to decide which pump is ideal for you.
A flow chart is often included by manufacturers for you to reference the rates of the pump’s GPH and total head pressure. Make sure to check out these charts before buying a pond pump to ensure that you’re getting the right one.
Kind Of Pond Pump
Another thing to consider , is it beneficial? Since its for maintenance it would cost you a lot? so before buying as well you have to know the use and the difference between the kinds of pumps that you will be using.
Submersible pumps can be more affordable. It would also be easily hidden from view as it’s placed under the water. If you wouldn’t mind regularly cleaning the pump, a submersible type may be a good choice.
External pumps have more longevity and are more energy-efficient. They may involve more complicated plumbing compared to the submersible types, and may have more noise. You might also want to hide the external pumps to keep your garden’s aesthetic appeal.
Regardless if you choose a submersible or external pump, one major factor to consider is the product’s warranty.
If your pond has fish, the pump will have to run 24/7 so a good warranty system should be in place.
The Type Of Pipe And Plumbing
Choosing the proper plumbing can also be a factor when selecting the right pond pump. Using an incorrect type of pipe can cause friction and may reduce the water flow your pump can produce.
If your water flow is higher than 4,500, you may want to use a 2-inch diameter pipe. Otherwise, your water flow might be disrupted by the pipe itself.
It is also recommended that you use a flexible PVC pipe. Why? First it is easier to install, it can also handle all the twists and turns, and it will provide more water flow.
Since the pump will be running during the most of the day, you have to consider the electricity costs as well.
Most pumps indicate the amount of wattage it uses. Alternatively, you can look for how high the voltage or amps used by each pump. Amps can then be converted to watts by multiplying the amps by volts.
This formula can be used to calculate your operational costs:
Watts divided by 1000 x kWh x number of hours a day x 30.4 days per month.
Checking on reviews (online) about pond pumps also needs to be considered. This will give you ideas what type or kind you should use and will give you some sort of advices based from their experiences of using those types of pumps.
To help you choose a pump that is suitable for your needs, we’ve rounded up 5 top-rated pond pumps.
