3V–6V Micro Submersible Water Pump – Mini DC Pump for Projects & Cooling Systems

The 3V–6V Micro Submersible Water Pump is a compact and efficient DC-powered pump designed for small-scale water circulation and movement. Its lightweight yet durable construction allows it to be fully submerged in water, making it suitable for a wide range of applications including electronics projects, cooling systems, mini fountains, aquariums, and educational experiments.

This mini water pump operates on a low voltage range of 3V to 6V DC and can be easily powered using batteries, USB boost converters, or small DC power adapters. It delivers a stable flow rate of approximately 80 to 120 liters per hour, depending on the model and supply voltage. With a lift height ranging from up to 0.6 to 1.5 meters, it is capable of moving water efficiently in compact setups.

Designed for quiet operation and low power consumption, the pump is ideal for continuous use in hobby and DIY projects. The durable plastic housing ensures long-lasting performance, while the simple two-wire connection allows quick and easy installation without complex wiring. Its compact size makes it easy to fit into tight spaces or enclosed systems.

The 3V–6V Micro Submersible Water Pump is commonly used in mini fountains and waterfalls, aquarium water circulation, Arduino and robotics water projects, hydroponic systems, cooling solutions for small electronic components, science experiments, school projects, water level automation systems, and DIY water sprayers.

Choosing this micro submersible pump means selecting a reliable, low-voltage, and energy-efficient water circulation solution. Its ease of use, versatility, and compact design make it an excellent choice for makers, students, hobbyists, and engineers working on small-scale water-based projects.
