Are External Pond Pumps Better?

  • External pond pump parts
  • Variable speed pond pump
  • Waterfall pump

It’s a fact that most pond keepers and water garden builders prefer a submersible pump over an external pump. Submersible pumps are usually easier to install, which is why we generally recommend them to most beginners.

However, external pond pumps still have their very distinct advantages, especially if you have built a larger pond or plan on keeping more significant numbers of fish. Some of the biggest benefits that external pumps have over submersible pumps are listed below.

  1. External pumps save more energy than submersible pumps

    One of the most significant advantages that external pumps have over their submersible brethren is that they are far more energy-efficient than submersible pumps. The difference in your monthly energy bills isn’t going to be massive, but you will notice a difference.

    This is especially true with larger ponds. If you have a pond with more than 8,000 gallons of water, you will begin to notice a significant difference between an external pump and a submersible pump.

    The energy efficiency of a well-made external pond pump will more than make up for the difference in price over the course of a few years. For ponds under 1,000 gallons in size, you may not necessarily see a difference, but the pump will still be more energy-efficient.

  2. External pumps have more potential for your pond

    External pumps can flow more water than submersible pumps. That’s a given. However, external pumps are also able to remain more energy efficient while flowing higher volumes of water. They come with a higher level of customization, too.

    An external pond pump does not have the same limits that submersible pond pumps have so that you can use them in ponds of all sizes. Submersible pumps are, in general, designed to be used in ponds that are smaller than 10,000 gallons in size.

    As you’re required to move more significant amounts of water at higher pressure levels, the pump is going to need to work harder to meet the demands being placed on it. As your volume requirements increase, the amount of power required to move that water increases, too.

    External pond pumps do not face these issues because they sit above the water’s surface level so that the flow ratings can be significantly higher for the same (or less) energy. Many external pond pumps are rated using the horsepower model instead of the standard gallons-per-hour.

    That means the external pumps are rated at higher power levels and can easily be adjusted down, allowing you to purchase more pump than you need for the same price as a similar submersible model.

  3. External pumps are easier to clean and maintain

    Another benefit and probably one of the greatest you’ll find is that external fish pond pumps are significantly easier to clean and maintain. Since the pumps are located outside of your pond, accessing them for maintenance is simple to do.

    You’re not going to find yourself wading through the water, fighting through floating debris, or risking damaging your plumbing and electrical wiring while trying to get to the pump. With an external pump, everything you need to access is right in front of you.

    Because external pumps are not always surrounded by floating debris, you also do not have to worry about them getting clogged with the same floating debris. Instead, the debris makes its way into the filtration system, rather than your pump.

    If maintaining your filtration system and the pump is low down on your list of favorite hobbies, an external pump is going to be a blessing in disguise. When you want to keep your maintenance schedule to a minimum, external pumps are the best choice you can make.

How To Choose Right Right External Fish Pond Pump

Whether you’re looking for a 5,000 GPH external pond pump or something significantly smaller, like a 500 GPH external pond pump, there are certain factors you’re going to need to consider.

We’ve used each of those factors to help us while building our list of the best pond pumps above. Each will determine the size, type, and style pump you need for the kind of pond you’ve built and your end-goal for what you’re looking to achieve.

  1. Energy Consumption

    The amount of energy your pump consumes is going to determine the size of your electricity bills each month. As your pond grows in size, the amount of electricity being used significantly increases with each additional jump in the flow rate on the pump.

    Higher quality external pumps are going to be designed for higher levels of energy efficiency than lower quality pumps. In general, the more you spend on the pump, the more access you’re going to get to technology that improves the efficiency of your pump.

    Understanding a pump’s rated wattage requirements will help you dial in exactly what the pump is going to cost you to operate. Lower wattage ratings require less power and will reduce your monthly electricity bills.

  2. Flow Rate

  3. When you’re looking at external pumps, you’re going to encounter two different types: high head heights with a powerful flow rating and low head heights with a stronger flow rating.

    The difference between each type of pump and which one you should choose greatly depends on how you intend to install the pump in your pond.

    External pumps that utilize lower head heights are perfect for keeping your water circulating through the system but are not usually able to power water features, such as waterfalls. This is true even for the smallest water features. They will put the pump under too much stress.

    Pumps that utilize a higher head height with a stronger flow rating are a better choice if you’re trying to move large amounts of water through multiple water features. If you’re planning on installing a fountain or a waterfall, for instance, the higher head height and higher flow rating will provide enough pressure to keep your water features flowing without stressing the pump.

  4. Variable Flow

    Some of the external pumps you’ll come across will offer a feature called variable flow. This feature isn’t usually found on submersible pumps. It’s a feature that dramatically improves how you’re able to use your pump and save on your energy costs while you do it.

    Some pumps will only feature two different settings, either a high setting or a low setting. Other pumps will allow you a full range of control that is adjustable via a knob or flow control valve. If you are looking for a high-end model, you may get full digital control over the pump’s flow rate.

    While having control over your pump’s flow isn’t necessarily a requirement, many consider it a bonus that opens up new opportunities and ways to save energy. You can use the flow control to more accurately dial in power being delivered to your water features.

    To give you an example, you can increase the power of your pump during the warmer summer months when your fish require more oxygen. During the warmer months, the oxygen levels in your pond will be reduced.

    On the other hand, during the colder months, you can dial the power back to conserve energy while letting nature supply more oxygen to the colder water. Fish spend less time moving around during the cooler months, so they do not require the same amount of circulation.

    If you want to save money while still having control over the flow rate of your pump, you can also install a ball valve inline with the pump. This ball valve will let you dial in the pressure and flow of the pump and often costs less than pumps with variable controls built into them.

  5. Input Voltage

    Something else you’re going to need to consider before purchasing a new pump is the input voltage levels required. Some pumps will operate on 115 volts, while others will require 230 volts. These two ranges cover nearly every pump currently available.

    Lower powered pumps will operate on 115 volts, while higher-powered pumps will require 230 volts. For larger ponds, operating at 230 volts will reduce your energy costs by allowing the pump to work at increased efficiency.

    Smaller ponds, between 1,000 to 5,000 gallons in size will typically use pumps rated for 115 volts of power. However, you will need to look at the wiring you’re able to run to the pump’s installation site before you make the purchase.

    If you only have 115 volts running to the installation site, you may be required to install 230-volt wiring to support the larger pump. This could be a massive investment on your part if you don’t already have the ability to handle 230-volt pumps.

    When you’re comparing both types, instead of comparing voltage requirements, focus your efforts on the gallons-per-hour rating. It’s always going to cost less to operate a more powerful 230-volt pump at a lower gallon-per-hour rating than a 115-volt pump at the same rating.

  6. Suction vs. Self-Priming

    You’re going to see two more features while looking at different external pumps. The first is a flooded suction pump, and the second is a self-priming pump. The type you choose could affect the price tag you’re going to pay.

    Pumps will require being primed before you are able to use them. If you aren’t familiar with the term, it means filling their internal compartments with water so they can efficiently flow more water through the inlet.

    Without priming your pump, you are going to be attempting to move air instead of water. Physics will keep water from entering the pump. Without having water inside the pump, it could overheat and live a short lifespan.

    Self-priming pumps will prime themselves, as the name implies, while suction pumps will require being primed before using them. Self-priming pumps are typically more expensive than suction pumps, but they’re also less work to get up and running.

What Is The Best External Pond Pump?

After extensive research, we have found that the best external pond pump for most pond keepers is the Little Giant Direct Drive Waterfall Pump. It’s powerful, quiet, energy-efficient, and built to last with a warranty that keeps your investment safe.
