Engineering Plastics
Characteristics: It has good corrosion resistance and can tolerate some components in konjac materials well. Meanwhile, engineering plastics are lightweight, which facilitates the installation, handling, and maintenance of the pump. In addition, some engineering plastics have certain self - lubricating properties, which can reduce the friction between the rotor and the pump body, lower energy consumption, and extend the service life of the pump.
Application Scenarios: It is suitable for some konjac processing scenarios where high hygiene requirements are needed, the corrosiveness of the materials is not strong, and the working pressure is relatively low. For example, in small - scale food processing plants, it is used to transport materials such as konjac gel.
Cast Iron
Characteristics: Cast iron has high strength and hardness and can withstand relatively high pressure. Therefore, it is suitable for konjac rotary pumps with high working pressure. Moreover, cast iron has good wear resistance, which can reduce the wear of the pump body caused by material friction during long - term use and extend the service life of the pump body. However, the corrosion resistance of ordinary cast iron is relatively weak, and special anti - corrosion treatments such as painting and galvanizing are required to improve its corrosion resistance in the konjac material environment.
Application Scenarios: In the production lines of some large - scale konjac processing enterprises, when it is necessary to transport konjac materials through long pipelines under high pressure, the pump body made of cast iron can better meet such working conditions.
Ceramics
Characteristics: Ceramic materials have extremely high corrosion resistance and can resist the erosion of almost all chemical substances. They can tolerate various components that may be contained in konjac materials well. At the same time, ceramics have a very high surface smoothness, and the friction of materials flowing in the pump body is minimal. This not only helps to improve the pumping efficiency but also reduces the shearing and damage of materials during transportation, better ensuring the quality of konjac materials. In addition, ceramics also have good wear resistance and high - temperature resistance and can operate stably for a long time in relatively harsh working environments. However, the disadvantage of ceramic materials is that they are relatively brittle and have weak impact resistance. Special care is needed during installation and use to avoid the pump body being broken due to severe impact.
Application Scenarios: In the high - end konjac food processing field, the quality requirements for konjac materials are extremely high, and the pollution and damage to the materials during transportation should be minimized. At this time, the konjac rotary pump body made of ceramic materials can give full play to its unique advantages and meet the production needs of such high - quality products.
