Buying Guide for the Best Submersible Pump

Whether you’re running a fountain, an aquarium, or hydroponics, you need a high-quality water pump to keep everything flowing. Without this crucial piece of hardware, you won’t be able to enjoy each of these setups as much as you should. However, when it comes to pumps for these applications, the best kind is a submersible pump.

Today we’re going to take a look at the best submersible pumps, as well as go over some of the most critical aspects to pay attention to when buying them. These machines will make your life a lot easier, and they will ensure that you can enjoy your fountain or aquarium for a long time. Let’s see what they have to offer.

What is the Best Submersible Pump?

When it comes to any type of water pump, the action is simple - you’re moving water from one place to another, either with suction or a motor pushing the water through the system. A submersible pump operates the same way; however, it can be submerged in the water it’s moving.

The primary benefit of a submersible pump is that you have much more flexibility in where you can place it. Also, it can be a lot smaller and more accessible because you don’t need a massive motor. Since it’s in the water it’s moving, it works with much more efficiency than a dry pump.

Submersible pumps come in a variety of sizes to work in different conditions. Smaller units are perfect for aquariums and ponds, while larger ones can either work as a sump pump for a septic tank or to remove standing water from a particular location (i.e., after a flood).

How to Choose the Best Submersible Pump

Flow Rate

Because your goal with a pump is to move water through the system, you want something powerful enough to get the job done quickly and efficiently. Thus, you want to pay attention to the flow rate to ensure that you’re on the right track. When looking at pumps, the flow rate can either be listed as gallons per minute (GPM) or gallons per hour (GPH). The former is usually shown for high-powered pumps that can drain pools or flooded areas, while the latter is great for smaller applications, like hydroponics or aquariums. Another thing to look out for is an adjustable flow rate. Many times the pump will only be able to operate at one speed, which can be too fast for some situations. Having an adjustable system will enable you to get just enough power without going overboard.


Because we’re looking at submersible pumps, that means that you will likely be putting them in the areas that need pumping. As such, you want to pay attention to the size of the unit itself, as well as the dimensions of the intake and discharge valves. In some cases, you may need to feed a hose into the water, while other times you want to avoid clogging the motor with debris. Smaller intakes won’t get clogged, but they may not flow as quickly as larger ones.

Vertical Lift

In most cases, you won’t be able to discharge water at the same level from which you’re pumping. Unless you’re operating a pond or an aquarium where the water is staying in one place, lift will become an issue. The vertical lift dictates how far the water will travel upwards - it’s a direct reflection on the power of the motor. The more lift you have, the stronger the pump. Usually, smaller units will have about 6-10 feet of lift, while more massive ones can go up to 30 feet. Think about the area in which you will deploy the pump before getting one with more lift.

Who Needs the Best Submersible Pump?

We’ve been talking about various uses for these devices already, but here are a few different situations where a submersible pump can come in handy.

  • Aquariums
  • Ponds
  • Fountains
  • Flooded rooms/basements
  • Pools
  • Septic tank

If any of these applications sound good to you, then you will want to buy a corresponding submersible pump to ensure that you can make the most of your water usage. Although it can be tempting to get a unit that’s more powerful than what you need, consider the fact that it may move too much water at once, as well as drive up your energy costs.

Final Verdict

Because we’re looking at the best submersible Pump designed for different purposes, we want to provide you with our top pick for both small and large applications. For aquariums, ponds, and fountains, we highly recommend either Kedsum Pump, as they are extra reliable and easy to use. They deploy in minutes and won’t break down quickly. For pools, flooded areas, or septic tanks, you can’t go wrong with the Superior Pump. It has an incredible motor, and it’s built to last, even with continuous operation. No matter how much water you have to move, this is the pump that’s going to get the job done.
