DC 3–6V Mini Micro Submersible Water Pump – Low Voltage Water Pump for DIY Projects
Product Description
The DC 3–6V Mini Micro Submersible Water Pump is a compact, low-voltage pump designed for small-scale water circulation and DIY electronics projects. Its small size and DC operation make it suitable for educational demonstrations, miniature fountains, hobby projects, and compatible hydroponic or water-circulation setups.
Operating within a 3V to 6V DC supply range, this micro pump uses a magnetic drive mechanism to move water through its outlet. Its compact construction allows it to fit into space-limited projects, making it a useful component for students, makers, hobbyists, and electronics enthusiasts.
Whether you're building a small water feature, experimenting with fluid dynamics, or developing a DIY project, this mini submersible pump provides a practical solution for low-voltage water movement.

Usage Instructions and Safety Notes
Use a suitable DC power supply within the specified 3–6V range.
Check the pump's polarity and current requirements before connecting it to your circuit.
Ensure the pump is installed and submerged as required by the manufacturer's instructions.
Use compatible tubing that fits the outlet securely.
Disconnect the power before cleaning, repositioning, or servicing the pump.
Important: Do not operate the pump dry unless the manufacturer specifically permits it. Keep electrical connections and the power supply protected from water. The advertised flow rate and lift may vary with voltage, tubing, and operating conditions. For aquariums, confirm that the materials and pump design are suitable for the intended aquatic environment.
