Peristaltic pump hose material: silicone tube, ordinary rubber tube, fluorine rubber tube.
1, silicone tube: silicone tube is one of the most commonly used peristaltic pump hose material. Its main chain is composed of silicon and oxygen atoms alternately, with high temperature resistance, low temperature resistance and oil resistance quality performance. Silicone hose is widely used in the domestic biopharmaceutical industry, its biocompatibility is good, can be used as a pharmaceutical grade sanitary hose.
2, ordinary rubber hose: a wide range of rubber hose, different processes of the hose is suitable for different industries. Ordinary rubber hose is more resistant to organic solutions than silicone hose, but there are different degrees of chemical reactions to various types of organic substances, which may lead to discoloration or performance degradation. Ordinary rubber hose belongs to the cheaper pump hose, suitable for some of the pump hose material requirements of the industry is not high.
3, fluorine rubber hose: fluorine rubber hose is mainly characterized by resistance to corrosive and non-polar solvents, its main chain or side chain of carbon atoms containing fluorine atoms. Fluoroelastomer tubing is the best choice for conveying strong corrosive and non-polar solvents, but its cost is high. When choosing fluoroelastomer hose, you need to pick the right hose material according to the characteristics of the actual conveying medium.
Peristaltic pump hose role:
1, conveying fluid: peristaltic pump hose is mainly used for conveying a variety of liquids, fluid mixtures, gases and solids and other multi-phase mixtures. Its superior flexibility and corrosion resistance makes peristaltic pump hose can be adapted to a variety of complex conveying environment.
2, reduce shear: the working principle of peristaltic pumps is to realize the fluid through the compression of the hose to transport, so in the process of transporting the fluid can greatly reduce the shear force. This is ideal for conveying shear-sensitive, erosive fluids.
3, good sealing: peristaltic pump hose itself has a good sealing performance, without additional valves and seals. This makes the peristaltic pump has a good self-priming ability to idle, prevent backflow, and reduce leakage and maintenance problems.
4, simple maintenance: peristaltic pump hoses as wearing parts, compared to other parts of the replacement is more convenient. At the same time, because there is no need for valves and seals, the overall maintenance costs are lower.
5, improve pumping efficiency: peristaltic pump hoses can be selected according to the need to choose the right material and model to adapt to different transport needs. This can improve pumping efficiency and reduce energy consumption.
