Product Description
The DC 12V Mini Submersible Water Pump is a compact, versatile fluid-transfer pump engineered for small-scale automation, aquatic models, and DIY prototyping projects. Operating efficiently across a 3V to 12V DC range, it delivers a steady flow rate up to 0.8 liters per minute while maintaining a remarkably quiet and energy-efficient footprint.
Essential for automated plant watering systems, mini desktop fountains, cooling loops, and science experiments, this miniature pump integrates smoothly into custom microcontroller enclosures and automated liquid-dispensing setups.
⚠️ Operating & Fluid Tip: Never run this pump dry for extended periods, as dry operation can generate excessive heat and wear out the internal impeller. Ensure the pump is fully submerged or primed with clean water before applying power.
Technical & Architectural Highlights
Wide Operating Voltage: Flexible power input ranging from 3V to 12V DC allows adjustable flow rates and pressure output via PWM or variable power supplies.
Compact Submersible Design: Small physical footprint enables easy concealment inside reservoirs, tanks, and custom enclosures.
Quiet & Efficient Operation: Low-noise DC motor drive provides smooth liquid transfer without disruptive vibration.
Barb Outlet Fitting: Secure hose barb design allows easy attachment of standard silicone or vinyl tubing for leak-free routing.
