A compact and efficient mini submersible water pump designed for small-scale fluid movement in electronics, DIY, and automation projects. Operating on 3–6V DC, this pump is perfect for Arduino, ESP32, and battery-powered applications.
With a flow rate of up to 120 litres per hour and low power consumption, it provides a simple and reliable solution for pumping water in compact systems.
Key features
- 3V–6V DC operation – ideal for low-voltage systems
- Flow rate up to 120L/hour
- Low current consumption (~220mA)
- Compact and lightweight design
- Fully submersible for easy use
- Simple 2-wire connection
How to use
- Attach a suitable tube/pipe to the outlet nozzle
- Fully submerge the pump in water
- Connect to a 3–6V DC power supply
Note: Do not run the pump dry, as it relies on water for cooling and lubrication.
