JT-DC3W-3 Mini DC Submersible Pump | 3V – 5V
Product Overview
The JT-DC3W-3 from Pro Tronix is one of the smallest and most efficient submersible pumps available for hobbyists and students. Its primary advantage is its extremely low starting voltage, allowing it to run directly from two AA batteries, a USB power bank, or an Arduino’s 5V pin.
This centrifugal pump is fully waterproof and designed to be completely submerged in liquid. Its silent operation and tiny footprint make it the standard choice for desktop “Zen” fountains, DIY hydroponic starters, and school STEM experiments where safety and ease of use are priorities.
