DC 3-6 V Mini Micro Submersible Water Pump

DC 3-6 V Mini Micro Submersible Water Pump offers a compact and efficient solution for moving liquids in small-scale projects. Designed to operate safely within a low voltage range of 3V to 6V, this submersible pump is ideal for battery-powered systems, Arduino and Raspberry Pi integration, and educational demonstrations. Its small footprint allows for easy placement in tight spaces, while its capability to be fully submerged makes it perfect for circulating or draining water. Whether you are constructing a desktop water feature, automating a plant watering system, or building a small fountain, this micro pump provides reliable performance with minimal power consumption.

Key Features:

• Ultra-Compact Design: Its mini size allows for integration into small, portable, and discreet systems.
• Low Voltage Operation: Easily powered by common power sources like USB ports, battery packs, or microcontrollers (via a driver circuit).
• Submersible Operation: Designed for full immersion in water, ensuring efficient and quiet operation.
• Durable Construction: The housing and impeller resist corrosion from fresh water, providing a long service life.
• Energy Efficient: Draws minimal current, making it suitable for prolonged use in battery-operated projects.

Technical Specifications:

• Operating Voltage Range: 3 V DC to 6 V DC
• Rated Current: ≈ 100 mA to 200 mA (at 6V)
• Maximum Flow Rate: ≈ 80 to 120 L/H (Liters per Hour)
• Maximum Head (Lift): ≈ 0.3 m to 0.8 m

Mechanical Specifications:

• Motor Type: Brushed DC Motor
• Pump Type: Submersible Centrifugal
• Fluid Compatibility: Fresh Water (Do not run dry for extended periods)
• Outlet Port: Small tubular nozzle for hose attachment

Dimensions:

• Body Size: ≈ 45 mm x 30 mm x 25 mm
• Outlet Diameter: ≈ 7.5 mm (Outer Diameter)
• Cable Length: ≈ 15 cm to 20 cm
• Weight: ≈ 30 g

Pinout and Wiring:

• Red Wire (Positive): Connect to the power supply’s positive (+) terminal (3V to 6V).
• Black Wire (Negative): Connect to the power supply’s negative (-) or ground terminal (GND).
• Control Note: For control via a microcontroller (like Arduino), utilize a low-side N-channel MOSFET or a transistor to switch the pump’s ground connection, isolating the pump’s higher current draw from the sensitive control board.
