The next ten years the industrial pump market
It is estimated that by 2005, the total output value of industrial pumps will reach 15 billion yuan and the sales revenue will reach 16 billion yuan, 125% of that in 1998. Among them, the annual growth rate of industrial output during the "Tenth Five-year Plan" period was 5%; in 2010, the industrial pump industry's total industrial output value is expected to reach 18 billion yuan and sales revenue will reach 19.0 billion yuan, 150% of that in 2000. Industry economic benefits will be significantly improved. Domestic product market share will also be from the current 84%, increased to 90%. Among them, the thermal power, nuclear power and "three major chemical" in the key product market in 2005 and 2010, respectively, share of 75% and 80%. Enterprise's product development, trial production, processing equipment, such as the technical level and equipment capabilities will have a strong competitive edge. In the next 10 years, it is also the period when the pump industry will have the largest increase in foreign exchange earnings. It is estimated that the foreign exchange earning in 2005 and 2010 will reach 450 million U.S. dollars and 700 million U.S. dollars respectively, an increase of 2.5 times and 4.4 times that of 1998. The predicted value will also increase by 1.2 times and 2.9 times. The exports of products in 2005 and 2010 will account for about 25% and 32% of the total industrial output value. Products focus on the development for the supercritical thermal power units with the boiler feed pump, air-cooled thermal power generating units with pumps, nuclear power plant pumps, and gradually fill the oil, sea oil, oil and oil, petrochemical and other special pump blank, the formation of industrial pump industry New point of economic growth. According to the statistics of the Industrial Pump Association, the members of the association have enjoyed an average annual export growth of 200% at the rate of 200% in the past three years. It is estimated that the export of pump units of the Association of Pump Association in 2000 and 2005 will reach 160 million U.S. dollars and 300 million U.S. dollars respectively. Pump industry reached 200 million US dollars, about 450 million US dollars. Industrial pump exports are the main countries and regions, Southeast Asia, Bangladesh, Pakistan, South Africa and other places. Zhejiang Fengyu Group's submersible pump products, through the United States, Europe and other places to set up the Distribution Department, has opened sales of these areas in the region, and get better than the domestic sales of the benefits. At present, industrial pumps supply oversupply of ordinary products, high-level, high-quality special products in short supply, but also imported from abroad, the level of products and user requirements gap. The phenomenon of unreasonable industrial structure and product structure is particularly evident. The products have reached the advanced world level rarely, most of them only reach the level of the late 1980s and early 1990s and can not adapt to changes in the market demand structure. On the one hand the product backlog of serious, on the other hand the market much-needed product trial is too slow or shortage, rushed out of the traditional pattern of the product. The dynamic gap with foreign countries has not narrowed, and the situation is not optimistic.
