Development and Application of Pumps Overseas

The market perspective of oversea pumps was described. The pumps market of England in two years was analyzed. The future trend of pumps market in England and the characteristics of America were discussed. The development trends of pumps were discussed from the aspects such as efficiency,new materials,seal, pumps of varying speed and computer applications. The overhead of pumps was analyzed by using life cycle. For how to improve the pump's efficiency, using thermalplastic materials to make friction parts was introduced. For new materials,the use of new non-metal material was discussed. For instance ,PFA,ETFE,FVDF are all erosion assist materials. Due to environment pollution problem sealed pumps grows quickly. The magnetic-driven pumps are applied widely. The application of pumps in some fields such as in food industry was briefly described too.
