Danner® Supreme Hydroponics™ Recirculating Aerating Water Pump - Model 3 - 350 GPH

Danner® Supreme Hydroponics™ Recirculating Aerating Water Pump - Model 3 - 350 GPH

The Danner® Supreme Hydroponics™ Recirculating Aerating Water Pump is specifically designed for hydroponic nutrient delivery and aeration. The Model 3 delivers up to 350 GPH and incorporates an adjustable venturi that injects air directly into the flowing nutrient stream — stimulating root development by delivering oxygen along with nutrients. Oil-free magnetic drive technology ensures contamination-free operation. Can be used inline or fully submerged.

Key Features & Benefits

• Adjustable Venturi Aeration — mixes air into the water flow at the pump, delivering oxygenated nutrient solution directly to root zones.
• Stimulates Root Growth — combined water and air delivery promotes faster root development and healthier plants.
• Inline or Submersible Operation — install the pump inline in your irrigation line or fully submerged in the reservoir.
• Magnetic Drive, Oil-Free — no shaft seals, no oil contamination risk in your nutrient reservoir.
• 350 GPH Max Flow — sufficient capacity for a wide range of hydroponic system sizes.
• 1/2in FPT Inlet & 1/2in Barbed Outlet — connects to standard 1/2in hydroponic irrigation fittings.
• 10ft Power Cord — provides convenient placement flexibility in grow rooms.

Who Should Use This

Hydroponic growers who want to deliver oxygenated nutrient solution to root zones — particularly in recirculating systems like NFT, DWC, or flood-and-drain setups where aeration is critical to plant health.

Compatibility

1/2in FPT inlet, 1/2in barbed outlet adapter. Inline or submersible use. 10ft power cord. Model 3 (350 GPH max).

Frequently Asked Questions

How does the venturi aeration work?

As water flows through the venturi, it creates a pressure differential that draws air in and mixes it into the water stream — delivering dissolved oxygen along with nutrients to the root zone.

Is the venturi adjustable?

Yes — the venturi can be adjusted to control the amount of air mixed into the flow, letting you tailor aeration to your specific system and plant needs.

Can this be used inline (out of water)?

Yes — this pump supports both inline (external) and submersible installation.

Is this pump oil-free?

Yes — magnetic drive technology eliminates oil from the motor, ensuring your nutrient solution stays uncontaminated.
