DC 3V-6V Mini Micro Submersible Water Pump – Ultra-Quiet 120L/H Brushless Motor Pump for DIY Fountains, Aquariums, and Smart Irrigation Systems

The DC 3V-6V Mini Micro Submersible Water Pump is a compact, high-performance fluid-moving solution designed for hobbyists, engineers, and DIY enthusiasts. This "plug-and-play" module is an essential component for projects requiring controlled water movement without the bulk or noise of traditional industrial pumps. Whether you are building an automated plant-watering system with an Arduino or a decorative desktop fountain, this pump provides the reliability and efficiency needed for continuous operation. Unlike standard brushed motors that wear down over time, this pump features a brushless magnetic drive system. This design not only significantly extends the operational life but also reduces friction, allowing for near-silent operation. The pump is designed for "submerged" use, meaning it uses the surrounding water to dissipate heat, ensuring it remains cool even during prolonged cycles. Installation is straightforward: simply attach a 7mm or 7.5mm flexible tube to the outlet, submerge the unit in water, and connect it to a power source. Its low voltage requirements make it exceptionally safe for educational use and student projects. It is an ideal choice for smart home prototypes, hydroponic setups, and any application where precise, low-volume water circulation is a requirement.

Key Features:

High Efficiency & Low Power: Delivers a consistent flow rate of 80–120 Liters per Hour (L/H) with a remarkably low current draw (130mA–220mA), ideal for battery-operated projects.

Ultra-Quiet Brushless Design: Utilizes a brushless DC motor with magnetic driving technology, ensuring smooth operation with noise levels kept under 30dB.

Submersible & Compact: Fully sealed and waterproof design allows the pump to be completely submerged, while its miniature size ensures it fits into tight spaces in DIY models.

Impressive Lift Capability: Despite its size, it provides a maximum water head (lift) of 40cm to 110cm, suitable for small-scale vertical water features.

Corrosion-Resistant Build: Constructed from high-grade engineering plastic that resists wear and corrosion, extending the lifespan for fresh-water applications.
