The pump industry can use the advantage of a late comer to realize a span development. Compared to the developed country, the pump industry of our country is backward. But relative people point that the pump industry of our country may use a late comer advantage to realize span development. After joining in WTO, the pump industry of our country has to implement technology span development. In pump industry, there are many examples to develop products through technology span development, such as the double volutes high-pressure boiler water feed pump of Shenyang Pumps Factory, Shanghai Pump Factory, the slurry pump of Shijiazhuang Pump Factory, the screw pump of Tianjin Pumps Machinery Group Co., Ltd, and no-clogging pump and magnetic drive pump in pump industry and so on. There are technology span on these products and they're made directly with the level close to internation level. Some companies use advanced abroad technology to improve the products of their own to realize the technology span, for example, Shenyang Pump Factory utilizes abroad advanced technology "water-sucking reliability" to improve the rigidty and reliability of AY oil pump rotors and there is also technology development on anti-bite material application. AY pump replaced Y pump and occupies the most oil pump market. Just as "Winner takes all" theory advised by an American author, that is, in high technology field, only you are advanced in technology, even it's a single screw pump, you'll probably occupies the most market of this field. In the 20 years of the reforming and opening, the pump industry of our country has great development in scale, power, technology base and human resource and other aspects. It provides economic and technology base for technology span development. The pump industry of our country has the ability to realize technology span development, and only the technology span development is carried out, the difference between our country and the developped countries can be reduced and we can catch up or surpass the international advanced level.
