A simple DC-powered air pump for inflatables and air-powered projects. Power it with ~4.5V (5V works fine) and it draws about 500mA, making it easy to run from the same supply as your DC motors or servos. The pump sucks air in from the side of the casing and pushes it out the tubing port.
Control the flow rate with PWM using a power transistor, motor driver chip (such as the L293D), or any Adafruit CRICKIT board. Note that reversing motor polarity does not change the airflow direction — if you need both inflate and deflate, you'll need two pumps.
Key Features
- Flow Rate – 2.5 LPM (litres per minute)
- Max Pressure – -55 kPa (stall)
- Operating Voltage – ~4.5V DC (5V compatible)
- Current Draw – ~500mA
- PWM Compatible – Adjust flow rate with pulse-width modulation
Ideal For
- Inflatable robots and art installations
- Air-powered maker projects
- Pneumatic experiments and prototyping
- Student and beginner electronics projects
Package Contents
- 1× Air pump DC motor (ZR370-02PM)
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- duty cycle
- The fraction of time a signal or power source is switched on during each repeating on/off cycle, usually given as a percentage. It is central to PWM (pulse-width modulation), where adjusting the duty cycle controls things like LED brightness, motor speed or heater power, and on devices such as proximity sensors it can also affect detection range, response speed, accuracy and power use.
- 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.
