In the production chain of chemical, pharmaceutical, environmental protection and other industries, chemical process pumps are key equipment for conveying various corrosive, high-viscosity, flammable and explosive media. Their stable operation is directly related to production efficiency and safety. From raw material transportation to finished product filling, this type of special pump plays an irreplaceable role in many fields with its corrosion resistance, wear resistance and precise quantity control.
In the field of petrochemicals, chemical process pumps need to handle complex media such as crude oil, acid and alkali solutions, and organic solvents. In the catalytic cracking unit of the refinery, the high-temperature magnetic pump can convey residual oil above 300°C, and its shaft seal-free design avoids the leakage risk of traditional pumps; in fertilizer production, the fluorine-lined centrifugal pump withstands the strong corrosion of ammonia water and nitric acid, ensuring the continuous operation of the synthetic ammonia process. This type of pump uses special materials (such as Hastelloy, polytetrafluoroethylene) and structural optimization to stably convey media under high pressure （up to 30MPa） and strong corrosive environments, providing reliable power for the petrochemical industry chain.
Pharmaceutical production has strict requirements on the cleanliness and precision of medium delivery, and chemical process pumps show their refined advantages in this field. In the antibiotic fermentation process, sanitary diaphragm pumps use food-grade rubber diaphragms to avoid contact between the medium and metal parts to prevent contamination; on the oral liquid filling line, the metering gear pump controls the delivery of liquid medicine with a flow accuracy of ±0.5% to ensure the accurate dosage of each bottle of medicine. In addition, the design of online cleaning （CIP） and online sterilization （SIP） allows the process pump to meet the GMP certification standards and help pharmaceutical companies achieve compliant production.
In the treatment of industrial wastewater and municipal sewage, chemical process pumps undertake core tasks such as acid-base adjustment and sludge transportation. In the electroplating wastewater treatment station, the self-priming chemical pump transports wastewater containing chromium and nickel to the reaction tank, and its wear-resistant impeller can resist the wear of particulate matter in the sewage; in the treatment of landfill leachate, the screw pump uses strong suction to send high-viscosity leachate into the membrane filtration system, solving the problem of easy clogging of traditional pumps. The efficient operation of this type of pump provides a stable medium circulation power for sewage treatment to meet the discharge standards.
In fine chemical production, there are many types of media with different properties, and the diversity of chemical process pumps is fully reflected. In the production of coatings, rotor pumps can convey high-viscosity slurries containing pigment particles to ensure uniform mixing; in the manufacture of electronic-grade chemicals, high-purity fluoroplastic pumps convey ultrapure water and photoresists, and their low precipitation characteristics meet the ultra-high purity requirements of the semiconductor industry. By changing the pump type and material, chemical process pumps can quickly adapt to different production needs and help enterprises to produce flexibly.
With the transformation of the chemical industry towards green and intelligent, chemical process pumps are upgrading towards high efficiency, energy saving and intelligent monitoring. The new generation of process pumps equipped with a variable frequency control system can automatically adjust the flow rate according to the working conditions and reduce energy consumption by more than 30%; the remote monitoring system can provide real-time warnings of leakage, overpressure and other abnormalities, adding protection for safe production. As the "power core" of industrial production, chemical process pumps will continue to inject stable kinetic energy into the efficient operation of various industries.
