Active Aqua Dual Diaphragm Air Pump — 25 L/Min, 4-Outlet

Give Every Reservoir the Oxygen Roots Need to Thrive

Low dissolved oxygen in a reservoir slows nutrient uptake and invites root problems — and a noisy, underpowered air pump that can't keep multiple buckets aerated just compounds the issue.

The Active Aqua Dual Diaphragm Air Pump pushes up to 25 L/minute of air through a multi-outlet divider built for quiet, consistent, high-volume output, the kind of steady aeration roots depend on around the clock.

Its four separate channels accept standard 0.25" tubing and, with the addition of distribution tees, can deliver aeration via air stones to as many as twelve hydroponic buckets or system reservoirs from a single unit.

Key Features & Benefits

• Up to 25 L/minute max output — delivers high-volume airflow suited to multi-bucket and multi-reservoir hydroponic setups, not just single-tank systems.
• Four-channel multi-outlet divider — splits output into four separate lines that accept 0.25" tubing, and can extend to up to twelve points of aeration with distribution tees.
• Quiet, consistent dual-diaphragm operation — runs steadily without the disruptive noise that makes some air pumps impractical for living spaces or shared work areas.
• Replaceable diaphragms — extends the working life of the pump — when output starts to fade, swapping diaphragms restores it to like-new performance instead of requiring a full replacement.
• Rated 3.77+ psi pressure — provides enough output pressure (0.026 kPa) to drive air stones across multiple lines without losing performance at the far end of the run.
• Includes an 8.3' heavy-duty 120V power cord — reaches standard outlets without forcing awkward placement near the reservoir setup.

Who Should Use the Active Aqua Dual Diaphragm Air Pump

This pump suits hydroponic growers running multiple buckets, reservoirs, or deep water culture systems who need reliable, high-volume aeration from a single unit. It's also a fit for anyone replacing a noisy or underpowered pump, or scaling up from a single-reservoir setup to a multi-point system that needs four (or up to twelve, with tees) independent aeration lines.

Setting Up Multi-Point Aeration

Each of the four outlets accepts standard 0.25" tubing and can run directly to an air stone, or be split further with distribution tees to cover up to twelve buckets or reservoirs from one pump. Because the pump uses replaceable diaphragms, growers can restore full output down the road without replacing the entire unit — a meaningful advantage for an aeration system meant to run continuously.

Frequently Asked Questions

How many reservoirs or buckets can this pump handle?

The pump provides four independent outlet channels, and with the addition of distribution tees, output can be split further to aerate up to twelve hydroponic buckets or system reservoirs from a single unit.

What size tubing does it use?

Each of the four outlets on the multi-outlet divider accepts standard 0.25" tubing, which is the common size used with most air stones and aeration accessories in hydroponic systems.

Is this pump loud?

No — it's built for quiet, consistent operation, which makes it practical for grow spaces located near living areas or shared workspaces where pump noise would otherwise be disruptive.

What happens when the diaphragms wear out?

Because the diaphragms are replaceable, output can be restored to like-new levels by swapping them rather than replacing the whole pump — a meaningful cost and maintenance advantage for a unit meant to run continuously.

What's the maximum output and pressure rating?

The pump delivers up to 25 L/minute of airflow with a pressure rating greater than 3.77 psi (0.026 kPa output pressure), enough to drive air stones across multiple lines without a significant performance drop-off.
