Zeddflow 12V DC 20W Submersible Dual Power Water Pump

Whether you’re building a solar-powered water system, setting up a garden fountain, or need a dependable pump for aquariums and hydroponics, the Zeddflow 12V DC Submersible Water Pump is engineered to deliver quiet, efficient performance day after day.

Key Features:

Dual Power Compatibility — Runs directly on solar (with an appropriate DC-DC buck converter, since most solar panels output higher voltage than the pump requires) or a standard 12–14V DC power supply, giving you the flexibility to go off-grid or plug into a conventional setup.
Ultra-Low Noise — Operates at less than 35dB, so it runs quietly enough for indoor aquariums, bedrooms, or peaceful outdoor spaces without a constant hum.
Reliable Flow & Lift — Delivers up to 800L/H flow rate with a vertical lift of approximately 3m at 12V (up to 3.5–4m at 14V). Note that flow rate decreases as vertical lift increases, which is standard for pumps of this type.
Fully Submersible Design — Must be placed directly in water; this pump does not have suction capability and is not designed to draw water from outside the source.
Optimized for 9mm Tubing — Lift and flow specifications are tested using 9mm ID soft tubing. Using a larger diameter tube will reduce lift performance, so 9mm is recommended for best results.
Compact & Durable Build — Built with a sturdy housing and dual threaded ports for easy inline installation into your existing water system.

Ideal Uses:
Solar water pumping systems, garden fountains and ponds, aquariums, hydroponic setups, small-scale irrigation, and other DIY water circulation projects.
