(Summary description)  The peristaltic pump tube is extruded by platinum vulcanization process, which eliminates the precipitate problem often encountered in other vulcanization methods. So how do we choose the right peristaltic pump tube?   First of all, suitable peristaltic pump tube should have the following characteristics:   1. it has a certain elasticity, and the tube can quickly restore shape after radial compression (Shore hardness: 40~80).   2. it has a certain wear resistance.   3. have the ability to withstand pressure.   4. no leakage (good air tightness).   5.low suction, temperature resistance, no aging, no swelling, corrosion resistance, low precipitation.

Information

  The peristaltic pump tube is extruded by platinum vulcanization process, which eliminates the precipitate problem often encountered in other vulcanization methods. So how do we choose the right peristaltic pump tube?                 

  First of all, suitable peristaltic pump tube should have the following characteristics:            

  1. it has a certain elasticity, and the tube can quickly restore shape after radial compression (Shore hardness: 40~80).

  2. it has a certain wear resistance.                                   

  3. have the ability to withstand pressure.                                

  4. no leakage (good air tightness).                                            

  5.low suction, temperature resistance, no aging, no swelling, corrosion resistance, low precipitation.    

  Secondly, when choosing the peristaltic pump tube, pay attention to the following conventional indicators:

  1. chemical compatibility                                           

  When pumping corrosive fluids, the key is to select the correct pump material. Selecting the wrong pump material will result in danger, which may damage equipment and endanger personal safety. Please refer to the chemical compatibility table for each purpose supplied by the manufacturer of tube.                     

  In addition, tubes should be tested before using new or unlabeled chemicals. Immerse a small tube into the fluid. After a period of time, check tube size, color, weight and intensity changes.   

  2. pollution-free   

  Fluid isolation is very important in many applications, such as laboratory research, pharmaceutical, biotechnology production and so on. A large number of studies have demonstrated that silicone tubes and silicon based materials do not react with various biomaterials. There are other kinds of materials that also have such properties, and can meet the requirements of USP Class VI. Some pumps employ pump components made of inert PTFE material.

  3. flexural resistance

  The ability of different pipes to bear roller repeatedly rolling is also different. Generally speaking, the service life of the pump tube is determined by the combination of the specific size of the pump tube, the material of the pump tube, the type of the pump head and the running speed. The service life of the pump tube or the flexural yield limit in the pump is the primary consideration before putting into the new application. Selection of pipe materials with greater flexural resistance, adoption of thicker pipe walls, and use of lower operating speed can maximize the use of the pump mission.

  4. definition

  For some applications, in order to clearly understand the pumping or dry operation process, it is very valuable to observe the movement of fluid through the pipe. But on the other hand, opaque pipes are good for some photosensitive fluids.

  5. hardness

  The hardness of pipe wall is very important for determining the pumping capacity of a specific pipe. If the pump tube is too soft, it will be damaged easily. If the pump tube is too hard, the pump will not work. The physical properties of specific pipes can be determined by hardness tester (such as Shore A).
