Petrochemical industrial pumps for the development trend

International petrochemical pump manufacturers mainly Switzerland Sulzer company, Germany KSB company, the United States Gaussian company. Petrochemical pump production technology is more mature, more varieties of specifications, a high degree of standardization, the main direction of development is large-scale, high-speed, mechanical and electrical integration and complete pump products. In particular, high temperature pump, cryogenic and cryogenic pumps, high-speed pumps, precision metering pumps, corrosion-resistant pumps, viscous media and transport medium with solid particles pump, shielded pump technology has developed rapidly. More than 100 domestic manufacturers, formed more than 100 series, more than 2,000 varieties of pump products manufacturing technology and production equipment to meet the needs of petrochemical production. Compared with foreign countries, the domestic petrochemical pump in the design theory, design methods are relatively backward, product development and more use of imitation and analog methods, the lack of theoretical basis and experimental research data; processing equipment and technology level is relatively backward, the processing accuracy is low, the production efficiency Low; product serialization and generalization is not high, less variety of specifications; pump efficiency, quality and reliability, sealing performance, corrosion resistance and so there is a big gap compared with foreign countries, so there are more petrochemical pump imports .
