3V–6V DC Mini Submersible Water Pump (3W)

Automate your DIY liquid systems with our versatile 3V–6V DC Mini Water Pump series. Running on a low-voltage 3W brushless DC motor, these compact pumps are ideal for micro-irrigation, automated plant watering systems, desktop fountains, aquariums, and custom fluid mechanics projects.

Designed for low noise, continuous operation, and ultra-low power consumption, they interface effortlessly with microcontrollers and single-board computers—including Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and Raspberry Pi Pico—via relays, MOSFET modules, or motor drivers.

Choose Your Variant

Select the exact form factor and power connection needed for your project build:

• White Vertical (USB Connector): Designed to stand upright at the bottom of narrow water reservoirs. Features a pre-fitted 5V USB plug for instant plug-and-play operation with power banks, USB wall chargers, or single-board computers like the Raspberry Pi.

• Black Horizontal (USB Connector): Low-profile horizontal orientation providing high stability on flat surfaces with suction cup mounting. Includes a 5V USB plug for easy power connection.

• Black Amphibious (Bare Wire / DC Leads): Engineered for maximum versatility—works fully submerged underwater or inline (external) on dry land. Features bare power wire leads for direct soldering, screw-terminal connections, or breadboard wiring.

Key Features

• Wide Operating Voltage (3V to 6V DC): Flexible power options—run directly from 3.3V/5V microcontroller circuits, 5V USB ports, 4.5V AA battery packs, or small solar panels.

• Quiet & Efficient 3W Motor: Brushless magnetic drive delivers smooth water circulation up to 80–120 L/H with minimal operating noise.

• Compact Footprint: Easily hides inside small reservoirs, hydroponic trays, tabletop fountains, and smart gardening enclosures.

• Multi-Platform Automation Ready: Pair with soil moisture sensors, relays, or PWM speed controllers on Arduino, ESP32, ESP8266, and Raspberry Pi.
