Working Principle
A special rubber hose with smooth inner surface and reliable strength is installed inside the pump, which will be extruded by a pair of compression rollers, making the medium convey in one direction without backflow. After conveying the medium, the hose will get back into shape due to its elascity and the force of side guide roller. At this time, the high vacuum in the hose makes it suck the medium again. Then the medium will be extruded by compression rollers and discharge from the hose. By this cycle, the medium will be sucked and discharged again and again.
