DC3-5V Horizontal mini water pump

The DC3-5V Horizontal Mini Water Pump is a compact, ultra-low-voltage submersible pump commonly used in DIY projects, aquariums, and miniature fountains. Operating quietly, it features a brushless motor and is ideal for moving small amounts of water in compact spaces. [1, 2, 3, 4, 5]

Key Specs & Features:

• Voltage: 3V to 5V DC
• Flow Rate: \(80 - 120\) Liters/Hour
• Max Lift: \(40 - 110\) cm
• Outlet Diameter: \(7.5\) mm (approx.)
• Operation: Can be fully submerged [1, 2, 3, 4]

Why It's Used:
This pump is highly favored by hobbyists for Arduino-based automated plant waterers, small-scale hydroponics, PC cooling loops, and desktop water features. It can be conveniently powered via a USB port, power bank, or standard batteries. [1, 2, 3, 4]

Note: It should never be run dry (without water) for extended periods to avoid overheating and motor damage. [1, 2]

If you are currently building a project, let me know:

• What specific application you are designing for (e.g., hydroponics, fountain, cooling system)
• If you need advice on powering it (e.g., using batteries, USB, or microcontrollers
