Danner Supreme Hydro-Mag Recirculating Water & Air Pump 1200 GPH — Adjustable Venturi, Submersible/Inline

The Danner Supreme Hydro-Mag 1200GPH is a compact recirculating water and air pump that delivers up to 1200 gallons per hour with an adjustable venturi for added aeration.

This pump is built for hydroponic systems and other recirculating applications where reliable flow, aeration and continuous duty operation matter. Designed for either inline or submersible installation, the unit uses magnetic drive technology and a vortex impeller to run efficiently and oil-free. UL listed and backed by a 5-year limited warranty, it balances performance and longevity for small to mid-size grow setups.

How does the pump keep nutrient solution moving and oxygenated?

The Hydro-Mag combines a high-efficiency vortex impeller with an adjustable venturi to introduce air into the water stream, improving dissolved oxygen without adding separate aerators. Magnetic drive construction eliminates oil seals, allowing maintenance-free continuous operation in hydroponic reservoirs. Flow and aeration can be tuned to match plant needs, helping to prevent stagnant zones.

• Maximum flow rate: 1200 gallons per hour (GPH)
• Adjustable venturi on applicable models for on-demand aeration
• Vortex impeller design reduces clogging from particulates
• Magnetic drive means oil-free, seal-less operation for longevity

Can I use this pump submerged or inline, and what fittings are included?

The unit is versatile: mount it submerged in a reservoir or install it inline in your plumbing. It features a 3/4" FPT inlet and MPT outlet and ships with a 1/2" barb to 3/4" NPT fitting so you can connect common tubing or rigid pipe. A 10-foot power cord and clear electrical ratings make placement flexible for most grow spaces.

• Submersible or inline capable for installation flexibility
• 3/4" FPT inlet and MPT outlet for standard plumbing connections
• Includes 1/2" barb x 3/4" NPT adapter for hose hookups
• 10' power cord and electrical spec: 110 watts / 1.5 amps

How do I choose the right size pump for my hydroponic setup?

Select a pump based on daily water needs and the vertical lift (head height) required. Estimate the total gallons you need circulated each day and factor in head loss from fittings and tubing; choose a pump whose flow at that head meets your coverage requirements. The Supreme Hydro-Mag family covers a range of flows—this 1200 GPH model suits tables or multi-tray systems needing robust circulation.

• Calculate required flow by estimating daily water turnover and system size
• Account for head height: vertical distance the pump must lift water
• Match pump flow at your expected head to ensure even nutrient distribution
• Use larger pumps for vertical or multi-level systems to prevent starvation

What are the operational limits and warranty details?

The pump provides continuous duty operation and is designed to be energy-efficient for prolonged use. Shut-off head is approximately 13.5 feet when used with a 4x4 flood table size; electrical draw is modest at 110 watts. Danner lists this model with a 5-year limited warranty and UL certification for safety assurance.

• Continuous-duty rated; suitable for long run times
• Shut-off capacity around 13.5' for typical flood table scenarios
• Energy draw: 110 watts / 1.5 amps for efficient operation
• UL listed and covered by a 5-year limited warranty

Who is this for: Growers building small to medium hydroponic systems, vertical gardens or flood tables who need a dependable, oil-free recirculating pump with the option to add aeration. It suits hobbyists upgrading from basic pumps and commercial users who want a durable unit with straightforward plumbing compatibility and long-term warranty support.
