The USB Mini Submersible Water Pump is a compact DC pump designed for low-voltage fluid transfer and circulation applications. It operates within a 2.5–6V DC range and uses a brushless magnetic driving mechanism for stable and efficient performance. The pump delivers a flow rate of up to 120 L/h with a maximum lift height of 1.1 m, making it suitable for small-scale systems. Built with engineering plastic, it ensures durability and resistance to continuous operation. Ideal for DIY projects, cooling systems, aquariums, and educational experiments.
