Mini DC 3–6V Submersible Water Pump for Arduino and DIY Projects

Product Description

The Mini DC Submersible Water Pump (3V–6V) is a compact, low-power, and efficient micro water pump ideal for DIY electronics, Arduino projects, aquariums, fountains, hydroponics, and cooling systems.

Designed for quiet operation and continuous use, this pump can be used in both horizontal and vertical orientations, providing excellent flexibility for space-limited setups. With a working voltage range of 3V to 6V DC, it delivers a steady water flow while maintaining low power consumption (≈3W).

Its durable plastic body ensures corrosion resistance and long lifespan, making it perfect for mini fountains, water displays, small cooling systems, and automated watering projects.
