Pumps

What type of pond pump do I need?
The type of pond pump you need depends on the specific requirements of your pond. If you’re looking to power a waterfall, fountain, or filtration system, a higher flow rate pump will be necessary. Submersible pumps are ideal for small to medium-sized ponds and sit underwater, whereas external pumps are better suited for larger ponds or setups that require easy maintenance. Make sure to choose a pump that matches the size of your pond and the volume of water you need to move to ensure optimal performance.

How do I calculate the right size pond pump for my pond?
To select the right size pump, it’s important to calculate your pond's water volume. For general circulation, your pond pump should be able to move the total volume of water in the pond once every two hours. For example, if your pond holds 1000 litres of water, a pump with a flow rate of at least 500 litres per hour is recommended. For ponds with additional features like waterfalls or filtration, you may need a pump with a higher capacity to handle the extra demand. If you need some help with calculating the correct size pump please see our pump and filter calculator.

How do I maintain my pond pump?
Proper maintenance of your pond pump is key to extending its lifespan and ensuring efficient operation. Regularly clean the pump’s filter to prevent debris build-up, which can reduce flow or cause the pump to overheat. In colder months, it may be beneficial to remove and store your pump, especially in regions that experience freezing temperatures. Make sure to periodically check the impeller and other moving parts for signs of wear, and replace components as needed to avoid malfunctions. Many modern pumps come with energy-efficient motors that require minimal upkeep, but still benefit from routine checks.
