Choosing a Pond Water Pump
A reliable pond water pump is one of the most important pieces of equipment in a well functioning ecosystem pond. Not only does the pump drive the filtration system, which is vital to keeping your pond healthy, but it also makes waterfalls, rivers and streams possible. The pump needs to be reliable enough to run 24 hours a day, 7 days a week without having problems or needing to rest. It also needs to be energy efficient so that the electricity costs to run the pump remain reasonable.
Choosing a pump happens to be one place that people often go wrong - either picking an incorrectly sized pump, a pump that’s unreliable, or a pump that’s an energy hog. Often people will try to save some money up front when choosing a pump, but it’s usually a big mistake since the running costs of a pump can far exceed the initial price of a pump over time. The most important features of a pump are reliability and efficiency. Once you've chosen a pump below, you can run our Pump Electrical Cost Wizard to calculate the running costs of a pump. Keep reading past our pump recommendations below to learn more.
Submersible Pumps We Recommend
Below you will find our Pond Water Pump Recommendations by Flow Rate. After running the pump selection wizard above, use the calculated flow rate numbers to choose a pump below! We only recommend the most reliable, energy efficient submersible pumps. Submersible pumps are meant to be placed directly in a pond, or in a pond skimmer, submerged in water.

4) Priming Pots / Strainer Baskets for External Pumps
Sequence Priming Pot / Strainer Basket - priming pots greatly simplify the process of priming an external pump. As well, each unit contains a strainer basket to filter out leaves and other debris from entering the pump. A priming pot is only needed when the pump is placed in a location that is higher in elevation than the pond surface. The priming pot allows the pump and lines to be filled manually with water before beginning operation.

Pump Vaults & Pump Socks
Although hiding a submersible pump inside a skimmer is our preferred way to install a submersible pump, sometimes it's not desired or possible to use a pond skimmer. In these cases, pump vaults and pump socks are great ways to conceal a submersible pump in a pond, while keeping debris, solids and fish from being sucked into the pump.
Submersible or External?
A submersible pond water pump is actually placed inside of the pond, below the surface of the water, usually inside of a skimmer. This is traditionally the most popular method of plumbing decorative ponds, mainly because of ease of installation. Just plop the pump in water and turn it on with no priming necessary. However, what submersible pumps make up for in simplicity, they loose in efficiency. A good external pump, which sits outside of the pond on dry land, can often pump the same amount of water as a submersible pump, but will use less electricity doing it. To calculate the cost of running a given pump per month, see our Pump Electrical Cost Wizard. We can’t stress enough how important an efficient pump is! External pumps are usually a little more expensive to purchase initially, but after looking at the energy savings, the money can easily be made back over time. Therefore, if your pumping requirements are over about 2500 gph, then we would recommend getting into a good external pump, like the Sequence 4K series mentioned above. Do you have less than 2500 gph? Go for a quality submersible like the Alpine Cyclone or the ShinMaywa. To learn more, see the pond water pump recommendations above, or see our page on submersible pond pumps or external pond pumps. Need to power your pump in a remote location nowhere near a power outlet? Maybe you need a portable generator from our friends at Johnny's Generators.
How much Flow do you Need?
The first step in choosing a pond or water garden pump is deciding how much water you need to pump per hour. As a minimum for proper biological filtration, your pond water pump should be able to pump the entire contents of your pond in one hour. That means if your pond contains 2000 gallons of water, as a minimum you’ll want 2000 gph (gallons per hour) flowing through your filter.
If you’re planning on having a waterfall in your pond, it’s important to consider the flow requirements of the waterfall as well. As a general rule, we recommend a minimum of 100 gph per inch of waterfall width. So if you have a 24” waterfall, that would equal 2400 gph. For a waterfall with more punch, try increasing the flow from 100 gph per inch up to 200 gph per inch.
Calculating Pond Head Pressure
Before choosing a pond water pump, it is very important to know what kind of head pressure you’re dealing with first. Head pressure is the combination of forces your pump must overcome to pump water from one end of the system to the other. For example, having a 5 foot rise in elevation (in the case of a 5 foot waterfall for example), will add 5 feet of 'head' to the system. Other things that increase head pressure include the length of pipe, pipe fittings, and equipment like filters and UV units. As you can see in the head pressure charts for the pumps above, the flow rate of the pump DECREASES as the head pressure increases. If you don’t take head pressure into consideration, the actual amount of flow coming out the end of your pumping system could be much lower than you initially planned for. For more detailed information on calculating head pressure, click here.
If you plan on keeping fish in your ponds, you may want to read our page on fish pond pumps, which outlines a few extra requirements for your swimming friends. Another more specialized type of pump is a solar powered water pump, which we currently have mixed feeling about due to reliability.
A pond water pump is also commonly referred to as a garden pond pump or water garden pumps.
