Adafruit Peristaltic Liquid Pump with Silicone Tubing - 5V to 6V DC Power

Move fluid safely with this efficient Peristaltic Pump, operable on 5V or 6V power. Unlike traditional pumps, it features a unique mechanism that presses silicone tubing to transport liquid, eliminating direct contact. Ideal for food, drink, and sterile applications, this pump ensures contamination-free operation.

The design includes a geared down DC motor providing robust torque, coupled with an internal roller pattern that smoothly pushes fluids through. This self-priming feature handles water effortlessly up to half a meter. Adjust the flow rate via PWM control, and reverse fluid flow by altering motor connections.

Compatible with power transistors and motor driver chips like the L293D, it integrates seamlessly with the Crickit for Circuit Playground Express. Use the crickit run motor blocks on Microsoft MakeCode to get started effortlessly. A 12V DC version is also available for heavier applications.

Comes with pre-installed silicone tubing and barbed connectors, though initial sterilization is required for hygiene. Note that the included tubing is not FDA/USDA compliant; ensure to source compliant tubing from suppliers like McMaster-Carr for food projects.
