The food grade filling liquid peristaltic pump tube's material is platinum vulcanized silicone.The Peristaltic Liquid Pump tube is extruded from special silica gel material through high temperature and high pressure, with smooth inner cavity and accurate size.The Peristaltic Metering Pump tube can meet the food hygiene, drug iodine, medical and other testing standards.It has the advantages of high abrasion resistance, high tear resistance, high resilience and so on. How to select a Dosing Pump tube: 1. The best way to select a tube is that to decide which materials are chemically suitable at first, and then choose the one which best meets the physical demands of the application. 2. For maximum tube life, use a large bore tube at low speed. For maximum flow rate use the largest tube at maximum speed. For maximum accuracy, use a small bore tube at maximum speed. 3. Suction lift depends on the tube restituting fully before the advance of the next roller. If it does not, the flow rate will be reduced. For maximum suction lift or pressure, use the smallest practicable bore size of tubing and run the pump at the slowest possible speed.
