A small submersible DC water pump for fountains, plant-watering systems, and other beginner projects. The pump draws water in from the side of the plastic casing and pushes it out through the tubing port. It runs on 3 V and draws approximately 100 mA, making it easy to drive from a microcontroller with a transistor or motor driver such as the L293D.

The flow rate can be adjusted using PWM. The pump must remain submerged (primed) during operation — it is not self-priming, and reversing polarity does not create suction.

Key Features

  • Submersible Design – Must remain underwater during operation
  • Low Voltage – Operates on 3 V DC
  • Low Current – Approximately 100 mA draw
  • PWM Compatible – Adjust flow rate with pulse-width modulation
  • Vertical Orientation – Water inlet on the side, outlet on top

Specifications

  • Voltage – 3 V DC
  • Current – ~100 mA
  • Type – Vertical, submersible

Ideal For

  • Small fountains and water features
  • Automated plant watering projects
  • Student and art installations
  • Arduino and microcontroller projects
