What temperature can plastic chemical pumps withstand?

　　Plastic chemical pumps are an important piece of engineering machinery that is widely used in process operations such as mixing, grinding and transferring chemicals. However, due to temperature, pressure and chemical properties, they must withstand certain temperatures in order to operate at higher temperatures.

　　First of all, the maximum temperature of a plastic chemical pump depends on its material, but generally plastic pumps are made of materials with a temperature range of -30°C to +120°C. Therefore, it can be said that plastic chemical pumps can withstand temperatures up to 120°C.

　　Using reinforced polypropylene material (FRPP) pump body can withstand the temperature is recommended below 65.C. The upper temperature limit for sealing materials NBR and EPDM is 80°C.

　　It is recommended that the pump body of polyvinylidene fluoride (PVDF) can withstand a temperature of 90.C or less. The upper temperature limit for sealing material VITON is 90°C.

　　With fluorine alloy plastic, polyperfluoroethylene propylene (PFPE), the pump body can withstand a recommended temperature of 150.C. Seal material Teflon is used.

　　Using reinforced polypropylene (FRPP) as the material of the pump can withstand temperatures up to 100 ° C,,, high productivity, low cost, suitable for conveying media conditions are not harsh occasions.

　　In addition, the maximum temperature of plastic chemical pumps also depends on the design of the pump, such as the model of the pump impeller, the number of vanes, materials and so on. If the pump is well designed, the effective temperature range of the pump can be increased to 200°C. The pump can be used for a wide range of applications.

　　Plastic chemical pumps can also use special materials and technologies to improve its maximum temperature resistance. For example, the use of polytetrafluoroethylene (PTFE), multi-layer feeder (MLP) and multi-layer valve seat (MLS) and other materials can improve the maximum temperature resistance of plastic pumps.

　　In summary, the maximum temperature of a plastic chemical pump depends on its materials, design and technology. Typical plastic pumps have a maximum temperature of 120°C. Through the use of special materials and technologies, the maximum temperature resistance of plastic pumps can be increased to 250°C or even higher.
