The AM325RDP Mini Dosing Pump is a compact, precision-driven peristaltic pump engineered for accurate liquid dosing, microfluidic control, and fluid circulation in DIY, educational, and automation projects. Designed for DC operation from 3V to 7V, the pump provides controlled flow rates with minimal mechanical complexity, making it ideal for embedded system integration.
Peristaltic pumps operate by compressing flexible tubing, which enables non-contaminating fluid transfer — a highly desirable characteristic when handling liquids that must remain isolated from pump internals. This pump’s miniature form factor makes it suitable for space-constrained setups, laboratory models, plant watering prototypes, and small-scale liquid handling systems.
Integrated with a brushed DC motor and compact gearbox, the AM325RDP delivers stable performance across its voltage range. It can be driven directly using a DC power source or interfaced through switching circuits controlled by microcontrollers such as Arduino, ESP32, Raspberry Pi, or STM32 via a relay or transistor/MOSFET driver.
