Why cast iron pumps will be replaced by stainless steel pump

　　Iron and stainless steel pumps are made of raw materials, relatively speaking, stainless steel centrifugal pump has a clear advantage in the future instead of cast stainless steel centrifugal pump into a high probability event .

　　It is reported that the slow development of stainless steel centrifugal cast iron pumps, water pumps and other six categories will be included in the scope of financial subsidies to promote energy-efficient products. Pump is an energy consumption, it is estimated that about 20 percent of national power consumption of the pump , and therefore , energy efficiency pump efficiency will be even more important. Will accelerate the process of financial subsidies or replace the pump in stainless steel iron , stainless steel centrifugal pump made ​​of stainless steel plate stamping , very smooth runner , avoid "secondary pollution" of water , high water use efficiency ( ratio of cast iron pump energy saving of about 10 % to 20 % ) , rather than cast iron pump is the trend of the times. But the cost is more expensive than cast iron pump stainless steel pump 20 % to 30% , three, four cities in the eastern part of our country at present , and the application is relatively small , the Midwest is the choice. Scope of the Ministry of Finance , centrifugal pumps and other energy-saving effect of subsidies , or to accelerate the process of replacing stainless steel pump iron .

　　With the development , improve the technological level of the country's development policies and stainless steel centrifugal pump manufacturing , the future price level will gradually reduce iron pump quit the stage of history instead of stainless steel centrifugal pumps, stainless steel centrifugal pump market is very optimistic about the future .
