Product Description (Detailed):

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.

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.

Applications:

• Aquarium water circulation and oxygenation

• DIY Arduino automatic plant watering system

• Miniature fountains and water features

• Liquid cooling for electronics

• Water transfer for solar or gravity systems

• Portable disinfectant spraying devices

Package Includes:

• 1 × DC 6–12V R385 Mini Water Pump
