Peristaltic pump moves fluid by compressing and releasing a flexible tube with rotating rollers, ensuring the fluid only contacts the tube interior. This design offers contamination-free, leak-free fluid transfer perfect for chemicals, viscous liquids, slurries, or sensitive media. It handles aggressive, abrasive or shear-sensitive fluids without damaging pump parts, and it can self-prime while resisting backflow. Its simple structure ensures low maintenance and easy tubing replacement. Peristaltic pump suits wastewater treatment, chemical processing, food and beverage, lab dosing, and industrial fluid transfer applications.
