The Boyu Submersible Water Pump is perfect for use in hydroponic systems that require the movement of nutrients to-and-from container areas, such as flood and drain, run to waste-systems, dripper systems, etc. To use this pump, screw one of the outlet attachments into the top of the unit and connect your tubing. Place the unit in your desired position and secure it into place using the suction pads on the underside. Always keep the 3-pin plug well away from any liquids! Ensure that any water-flow is well away from electrics before plugging the unit in and turning on at the mains.

How big of a water pump should I get is one of the most asked questions by new hydroponic growers. But the fact is there just isn’t a specific answer that fits for everybody. There are just too many variables in how people can design their hydroponic systems for there to be a clear cut answer that would be able to apply to every situation. The only answer that would apply across the board is get a bigger pump than you think you will need, because you can always reduce the water flow, but you can’t do anything to increases its maximum water flow.
However it’s actually much easier than it might seem to figure out what pump size you need than you might think. All you really need to know to do that, is know a few things about the hydroponic system your building first, and a couple things about submersible water pumps. Then you’ll be able to tell at a glance if a pump will work for your situation or not.
What you want to know about your hydroponic system first
Water volume and how high you need to pump it
Flood and Drain systems (Ebb & flow)
First you are going to want to know how much water your going to need to pump. It doesn’t mater what your using for the growing chamber, or how many of them you have, it’s the same simple process to calculate the water volume. If the container doesn’t have the gallon size written on it, just fill it up with water to the water level you want, but just make sure to keep track of how many gallons it takes. That gives you the water volume you need to fill/flood it.
If you plan to have multiple growing chambers, just multiply how many growing chambers you plan to have by the water volume in the one you tested. That will give you the total water volume you need to fill the entire system.
After you know the water volume you need to pump, you will need to figure out how high it will need to pump it above the water line in the reservoir. For that you will need to know where your going to be putting the system and reservoir. As an example, if your putting the system (growing chamber) on top of a table, and the reservoir on the ground near it, the system will probably be somewhere between 2 and 3 feet above the water line in the reservoir. If your mounting the system along a fence or wall, the height could be much different. Knowing how high the pump will need to pump the water up from the reservoir is a very important aspect of picking a pump (probably even the most important thing to know).
Once you know those two things about your hydroponic system, then you can go ahead and pick a good pump for your system. For more on picking the right pump, scroll down to the section on “What you should know about water pumps for Hydroponics.”
While drip systems are simple in nature, there are hundreds of different ways to construct them. But that also means there is almost no end to the variables that could affect the water flow from the water pump. However the same two things you need to know to pick a pump for a flood and drain systems are ultimately the same for all systems (including drip systems), “Water volume and how high you need to pump it.”
Naturally deciding on how much water (GPH) you want/need to run through your drip system is more difficult to calculate than a flood and drain system. It’s not as important because your not flooding a system in a specific time period, your just giving the plants a gentle soaking that can last 15 min, hours, or even 24/7. And you can easily adjust the soaking time with a timer.
Because of things like the size of your plants, how many plants your growing, the type of growing media your using, how much growing medium there is for each plant, how you built your system, if your using a timer to control the watering cycles, as well as how long between the watering cycles, even humidity levels, the amount of water volume you want to reach each plant per hour (GPH) can vary drastically. So there is no easy or set formula to go by for that. But as mentioned earlier, as long as each plant is getting a steady amount of dripping, you can adjust watering/wetness with a timer.
When considering a water pump for a drip system, water pressure will be the key to it working well. The more plants and dripprs you have, the more water pressure you will need. Submersible pumps used for hydroponics don’t give pressure ratings (psi). They only give gallons per hour (GPH) and “head height” (max height it can pump). The the higher the head height, the more water pressure the pump will have. Scroll down to read more about it in the section “What you should know about water pumps for Hydroponics.”
With a NFT system you don’t need to fill the system (growing chamber), you just need a constant flow 24/7 to all the plants. The water depth is shallow, only a few millimeters (¼ inch or so). So you don’t need a large volume of water to be pumped through it. Typically NFT systems are constructed using long tubes that are angled so the water flows downhill as it flows through the tube. The angle of the tube will control the water depth, as well as the speed in which the water flows through it (not the pump). The pump just needs to be able to keep up with how fast the water is flowing out of the tubes.
With the water depth being just a few milometers, you only need to pump a few gallons per hour through each tube. It doesn’t need to flow fast, but you definitely don’t want it to be stagnate. Stagnate water will become depleted of oxygen and nutrients quickly. Flowing water will provide a continues supply of both.
The water depth and flow rate will be the biggest factors in the gallons per hour you will be pumping. As an example, with a water depth of ¼ inch deep, and 4 inch wide tube, a 10 foot long tube will hold about ½ gallon of water. If you want to recirculate that half gallon of water every 5 minutes, that would give you 6 gallons per hour through each tube.
If you wanted the flow rate to be faster and changed the angle of the tube so it was recirculating that half gallon of water every 2-½ minutes instead, then you would be pumping twice as much water at 12 gallons per hour. The length of the tube in your NFT system isn’t really important, and wont affect the flow rate or GPH you need to pump. It will only affect the total amount of water needed in your system, but not how fast you recirculate it.
Now that you can figure out the GPH you will need to pump through each tube in your NFT system, just multiply it by the amount of tubes you plan to have in your system to get the total minimum GPH. But always get a pump that can pump more than you need. And don’t forget to take into account how high it needs to pump it. For more about pumps, scroll down to the section on “What you should know about water pumps for Hydroponics.”
There are two types of aeroponic systems. The true aeroponic system uses high pressure (60-90 psi). However most people refer to low pressure spraying systems as aeroponic systems as well.
High pressure aeroponic systems don’t really use a water pump due to the numerous cycle (on/off) times needed. They usually consist of a two sided tank with a rubber divider. The nutrient solution is in one side. And air in the other. Then an air compressor is used to pressurize the tank. A water line from the nutrient solution side runs to the misting heads, and a solenoid is used to open and close a valve in the water line at precise times using a cycle timer.
Low pressure aeroponic systems are what most people are referring to when they mention aeroponics. Low pressure systems use standard submersible water pumps, but still need a good amount of water pressure or the water will just trickle out of the sprinkler/mister heads. The more sprinkler heads your using, the more water pressure you will need. Unfortunately submersible pumps don’t give a psi rating to compare. They only give you GPH and head height, and GPH is a measure of volume, not pressure. Your best indicator of water pressure is the “head height” rating. It takes pressure to pump water up, so the more GPH it can pump higher, the more water pressure it will have.
What you should know about water pumps for Hydroponics
The water pumps used for hydroponics are just simply submersible fountain and pond pumps that you can get at most home improvement stores. Some manufactures also package them specifically for sale at hydroponic supply stores.
Once you know the minimum number of gallons you need to be pumped through your system, it’s easy to choose a pump. But we would recommend to make sure you choose a pump that can pump at least twice as much water than the minimum gph of what you need. That will allow you some flexibility in how you set things up, changes in the future, as well as make sure the pump doesn’t fall short of your expectations.
You can always easily reduce the water flow from a pump if you need to, but you cant ever make it pump more than it was designed to. Most pumps will have a flow restrictor built in, it’s just a cover that slides/pivots over the opening for the water inlet to reduce the water inlet opening size.
If you need to reduce the water flow even further, the easiest way to do it is just install a “T” connector in the tubing going to your plants, just above the pump and still inside the reservoir (like in the picture on the right). Then install a short piece of tubing on it so half the water goes straight back into the reservoir. If you want to fine tune the water flow even more, you can also add a valve on the end to adjust how much water goes back into the reservoir.
“A well made and powerful pump with separate pipes. One which is flexible and will easily attach to a sprinkle bar system, and another which attaches to a separate outlet to blow thousands of tiny bubbles into the aquarium to give excellent oxygenation. Choose the power unit to suit the size of you tank. A very good buy indeed.”
“Works a charm! Does the job and does it well.”
“Very quick delivery and a great pump. Very well packaged and with no issues.“
