Atman AT-107 Submersible Water Pump – 3500 L/h Adjustable Flow for Hydroponics & Soil

The Atman AT-107 Submersible Water Pump is the ultimate heavy-duty engine for your irrigation system, designed to deliver a massive, adjustable flow of 3500 liters per hour so your plants never miss a drop of nutrients.

Setting up an automated irrigation system can be stressful when you are constantly worried about uneven watering, weak pressure, or a pump that just can't handle the workload. Relying on cheap, unpredictable equipment leaves you feeling like you are winging it, with zero control over how much water actually reaches your canopy.

That lack of control quickly turns into a grower's worst nightmare. A pump failure or pressure drop means dry spots in your coco, clogged drippers, or a hydroponic system that starves your roots. Instead of chilling and enjoying your grow, you are constantly checking for leaks, stressing over nutrient lockout, and risking a ruined harvest just because your water delivery failed.

With the Atman AT-107, you eliminate those risks and take absolute command of your watering schedule. This powerful, fully submersible pump provides the exact pressure and reliability you need to keep your setup running smoothly, ensuring every single plant gets perfectly fed without you having to babysit the reservoir.

Unmatched reliability, fewer worries

When you drop this pump into your nutrient tank, you are investing in pure peace of mind. Its robust, fully submersible design means it operates quietly underwater, keeping your grow room stealthy and free from annoying vibrations. You won't have to deal with loud humming noises that ruin your chill vibe or give away your indoor garden's location.

Plus, its versatility is a game-changer. Whether you are running a complex Drip irrigation systems setup, a deep water culture, or just feeding a large soil bed, the Atman AT-107 adapts to your needs. The adjustable power lets you dial in the exact flow, so you never overwater or blow out your lines.

Total control over your irrigation

• Adjustable flow rate up to 3500 L/h: Because you can regulate the output, you can perfectly match the water volume to your system's size, which means no more overflowing trays or dry pots.
• Impressive 3.8m maximum head height: Thanks to its strong vertical push, you can easily pump water from floor reservoirs to elevated Grow Table setups, ensuring consistent pressure everywhere.
• Fully submersible design: By operating completely underwater, it naturally cools its motor and dampens sound, which translates to a longer lifespan and a whisper-quiet grow room.
• Multi-substrate compatibility: Because it works flawlessly with soil, coco, and Hydroponic and Aeroponic Systems, you have the freedom to switch up your growing style without buying new equipment.

How to set up and use your pump safely

Getting your Atman AT-107 up and running is super easy, but following a solid routine ensures it lasts for years without a hiccup. Here is how to set it up like a pro:

1. Prep the reservoir: Make sure your water or nutrient tank is clean and free of large debris that could clog the intake.
2. Connect the tubing: Attach your irrigation pipe securely to the pump's outlet nozzle, ensuring a tight fit to prevent leaks.
3. Submerge completely: Place the pump flat on the bottom of your reservoir. It must be fully submerged before you plug it in to prevent the motor from burning out.
4. Adjust the flow: Use the built-in regulator to set your desired water pressure before turning on the system.
5. Test the lines: Plug it in and watch your drippers or outlets. Tweak the flow dial if the pressure is too high or too low.
6. Maintenance: Once a month, unplug it, take it out, and rinse the filter sponge to keep the flow rate at its maximum 3500 L/h capacity.

Benefits of having everything under control

• Absolute calm knowing your plants are watered exactly when they need it.
• Fewer surprises like dry roots or flooded grow tents.
• A solid, automated routine that frees up your time to focus on pruning and training.
• Better nutrient distribution, leading to explosive growth and fatter buds.

Frequently Asked Questions

Can I use the Atman AT-107 outside of the water?

No, this is a strictly submersible pump. It needs to be completely underwater to keep the motor cool and function properly. Running it dry will damage the internal components.

Is it too powerful for a small grow tent?

Not at all! Thanks to the adjustable flow feature, you can dial back the power to suit smaller setups. It gives you the flexibility to use it in a compact tent now and scale up to a larger room later.

How do I clean the pump to maintain the 3500 L/h flow?

Simply unplug it, remove it from the reservoir, and pop off the front cover. Rinse the internal impeller and the intake slots with warm water to remove any salt buildup or algae.

Does it work with thick organic nutrients?

Yes, but if you are using heavy, sludgy organic feeds, we recommend cleaning the pump more frequently to prevent the intake from clogging and to maintain optimal pressure.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve burned through my fair share of cheap water pumps over the years, and let me tell you, waking up to a flooded floor or bone-dry hydro buckets is the worst feeling ever. When I switched to the Atman AT-107, that anxiety completely disappeared. It’s an absolute beast of a pump. The 3.8-meter head height is a lifesaver because I run my reservoirs on the floor and pump up to elevated trays, and this thing doesn't lose an ounce of pressure.

My personal trick? I always place a small piece of foam or a rubber mat under the pump inside the reservoir. Even though it’s already super quiet, the mat absorbs any micro-vibrations against the plastic tank, making it completely silent. If you want a reliable engine for your irrigation that you can just set and forget, this is the one.
