Product Description (Detailed):

Discover versatile liquid transfer capabilities with our compact and efficient DC 6-12V R385 Mini Aquarium Water Pump. This powerful yet small submersible self-priming pump is an ideal solution for a wide range of applications, from small aquariums and pet water dispensers to DIY projects and automated fluid systems. Its broad operating voltage range of 6V to 12V DC makes it incredibly adaptable, allowing you to power it with batteries, solar panels, or standard power supplies, depending on your specific needs.

Designed for convenience, the R385 mini water pump can be fully submerged in liquid, making it perfect for silent and effective water circulation in fish tanks or miniature fountains. Its self-priming capability means it can draw water up from a lower level without needing to be pre-filled, simplifying setup and operation. With a robust build, this pump is engineered for continuous duty, offering reliable performance for tasks such as creating small waterfalls, circulating nutrient solutions in hydroponic systems, or even serving as a compact cooling pump for electronic components. Its small footprint ensures it can be easily integrated into tight spaces, while its efficient motor delivers adequate flow rates for various low-volume pumping tasks. Whether you're an electronics hobbyist building a smart garden, an aquarist needing a reliable water circulator, or an innovator designing a new fluid-transfer system, the DC 6-12V R385 Mini Water Pump offers a dependable and cost-effective solution for all your miniature pumping requirements.

The R385 Mini Water Pump is a low-voltage DC motor-driven pump widely used in aquariums, automatic water dispensers, solar fountains, and electronics cooling systems. Operating on 6V to 12V, it offers flexibility in flow rate and pressure based on the voltage supplied.

It features a self-priming mechanism, allowing it to work even when mounted outside the water source, unlike typical submerged-only pumps. The sealed motor housing ensures minimal wear and long service life in moderate-duty cycles.

Compact and easy to integrate, this pump is perfect for hobbyists, students, and developers building automated plant watering systems, Arduino water level monitors, or portable sanitizing devices.

Technical Specifications:

How to Use:

1. Connect pump terminals to 6–12V DC power supply or Arduino relay circuit.

2. Use tubing on inlet and outlet ports (typically 6mm ID hose).

3. Prime the pump if necessary (dry run not recommended for long periods).

4. Securely mount pump to avoid vibration and ensure airflow for cooling.

For Arduino automation, use a transistor or relay module to control pump with digital logic.
