Mini Submersible Pump – Compact DC Water Pump, 3–6V
Mini Submersible Pump — 3–6V DC Water Pump
The Mini Submersible Pump is a compact, low-voltage DC pump designed for small-scale water movement in DIY electronics, hydroponics, and aquaria. Ideal for projects requiring gentle flow and silent operation, it can be fully submerged, drawing water from shallow containers or sumps.

What You Can Build With This
- Automatic plant watering system using a soil moisture sensor
- Desktop water fountain or mini waterfall display
- Aquarium water circulation or small sump system
- Liquid cooling loop for electronic components or small projects
Compatibility
The pump works with any 3–6V DC power source. It can be directly driven from a MOSFET or transistor with an Arduino, ESP8266, or Raspberry Pi. Ensure your microcontroller provides enough current via a driver circuit; a flyback diode is recommended to protect against voltage spikes.
Wiring Notes
Connect the red wire to positive (+) and black to negative (−). Use a 2N2222 transistor or L293D motor driver for speed control. Never run the pump dry for extended periods, as water acts as its lubricant and coolant.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, when driven via a transistor or motor driver shield. Direct connection may exceed pin current limits.
Can I run this pump continuously?
It is rated for intermittent use. Continuous operation above 4 hours may reduce lifespan; allow cool-down periods.
What is the maximum lift height?
The pump can lift water up to 0.6 metres vertically; flow rate decreases significantly above 0.4m.
