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

- 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
Package Contents
- 1× Submersible water pump with power wires
Jargon buster
Plain-language definitions for the technical terms used above.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
