## Description

A compact DC-powered air pump for inflatables and air-powered projects. Power it with ~4.5V (5V works fine) and it draws about 600mA, 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 – 1.8 LPM (litres per minute) Max Pressure – -55 kPa (stall) Operating Voltage – ~4.5V DC (5V compatible) Current Draw – ~600mA 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 (ZR320-02PM) Warning: This pump is for air only — not suitable for liquids. It is not rated for continuous use. Recommended duty cycle is ~50% (tested for 30,000 cycles of 10 seconds on, 5 seconds off). Place on soft foam or sponge to reduce vibration noise. Tip: Silicone tubing is not included. Grab some 3mm silicone tubing to go with this pump. Need more airflow? See the 2.5 LPM version. For liquid pumping, see our peristaltic pumps.
