At A Glance: Our Top 5 Water Pumps For Hydroponics

5 Best Water Pumps For Hydroponics

We’ve spent 36 hours researching and reviewing the water pumps below to come up with what we believe are suitable choices for hydroponic growers of all abilities.

1. Hydrofarm Active Aqua Submersible Water Pump, 400 GPH

The Hydropfarm Active Aqua is our top pick hydroponic water pump. While the unit is compact making it ideal for small systems it’s surprisingly powerful and at 400 gallons per hour (or 25-liter per minute) it should be good enough for most small domestic setups.

One thing we really like is how easy maintenance is, even for non-technical folks like myself it’s quick to strip down, clean and put back together. Plus it’s oil and BPA free meaning you don’t need to worry about anything contaminating your system.

2. EcoPlus 396 GPH (1500 LPH, 20W) Submersible Water Pump

Another great entry into our list of the best hydroponic water pump category, the 36 watt motor on the EcoPlus pump has the ability to push out up to 396 gallons per hour with an air lift of around 6.5 feet.

3. VicTsing 80 GPH (300L/H, 4W) Submersible Water Pump

If you’re looking for a solid water pump for your first hydroponics system then you can’t go far wrong with this one from VicTsing. The 4W motor has a maximum flow rate of 80 gallons per hour and can be adjusted using the to your requirements using the control knob.

4. Aquastore 400GPH 25W Submersible Water Pump

If you hate the noise that some water pumps make then you’re going to want to take a look at the Aquastore 400GPH 25W Submersible Water Pump. Not only does the pump run quieter than most other water pumps but it comes with an adjusting knob so you can tailor the flow rate to your system requirements.

5. Hydrofarm Active Aqua AAPW250 Submersible Water Pump, 250 GPH

We’re big fans of Hydrofarm pumps here at Authority Gardening so you shouldn’t be surprised to see another Hydrofarm Active pump on our list, this time it’s the AAPW250. This super reliable unit has a 250 gallon per hour flow making it ideal for those setups with a 25-gallon reservoir and with a maximum lift of 4.5 feet, it’s going to be suitable for the majority of home hydroponic systems.

What To Look For When Buying A Hydroponic Water Pump

With so many products on the market, we know it can be tricky to know the good products from the cheap Chinese imports that are going to break after a few hours of use. That’s why we’ve put together the quick guide below to help you get exactly what you need without getting ripped off.

In fact, this is the same criteria we used to pick and rank the products above.

How Big Is Your System?

So the most important question is – how big is your hydroponics system? If you’re a hobbyist then a pump capable of pumping 80-100 gallons an hour (gph) is more than capable, however, if you’ve got a larger setup then you’re probably going to want something with a minimum flow rate of 250 gallons per hour.

A good rule of thumb is to multiply your nutrient reservoir size by 10 and you’ll have a good gauge to choose the right flow rate – if you have a 30-gallon reservoir then you’ll want a pump with a flow rate of roughly 300 gph.

Air Lift

Within most the hydroponics systems such as Nutrient Film Technique or Ebb and Flow your reservoir will sit below the grow table, this is where you need a pump capable to pumping water up which is known as the air lift height. Again, the air lift hight will depend on your setup but this is something worth considering as a pump is useless if it can’t push the water from one container to another.

Wattage

Our final consideration is around the power required to run the pump. Hydroponics can get expensive once you consider that often you’ll be using lights, pumps, fans and humidifiers which is why we believe that the power required to run the pump should be taken into account.

The Bottom Line

So there you have it, our list of what we consider to be the 5 best water pumps along with a few things to watch out for when you’re shopping for your next pump.
