12V Peristaltic Liquid Pump with Silicone Tubing

This 12V peristaltic pump is a compact positive displacement pump designed for transferring and dispensing a wide range of liquids. Also known as a roller pump, it operates by compressing a flexible silicone tube with rotating rollers inside the pump head. As the rollers rotate, they continuously pinch and release the tube, moving the liquid through the tubing while keeping the pumped fluid isolated from the internal pump mechanism. The peristaltic design provides a self-priming function and allows the pump to handle liquids containing air bubbles. The pump can also operate without a continuous liquid supply for short periods, helping reduce the risk of damage caused by temporary dry running. This model features a convenient snap-on pump head design, allowing the pump head to be easily removed by hand for quick replacement and cleaning of the pump tube. Its compact structure makes it suitable for applications where installation space is limited. The flow direction can be easily changed by reversing the power supply polarity, making it a versatile choice for both simple liquid transfer and precise dosing tasks. The pump works with a 12V DC power supply and delivers a flow rate of 0 to 100 mL/min, with a speed range of 0.1 to 100 RPM. Its silicone tubing is compatible with a wide range of fluids, and the three-roller pump head ensures smooth and consistent pumping action. This 12V peristaltic pump is well-suited for laboratory equipment, DIY electronics projects, automated dosing systems, and other applications requiring reliable and contamination-free liquid handling.
