Recently, from a certain Industrial Group Valve Co., Ltd. Zhejiang certain good news: developed by the company's long axis XDBG Series ultra-high temperature concentrated sulfuric acid pump successfully shipped the first batch of products shipped Hubei three Ning.

        It is understood that under the long axis of the ultra-high temperature concentrated sulfuric acid pump is a special valve for cryogenic recovery systems company key equipment - a new pump acid pump development and design. The pump is a national initiative , reasonable structure design, the main flow components are developed by our company Material : XDS-9, XDS-8, XDB-6 and other corrosion resistant materials , and the choice of excellent hydraulic model . The pump stable performance, energy efficient, interchangeability, and easy maintenance.

        Because under the current sulfuric acid plant 's annual output of 20-30 million tonnes from the previous gradually increased to 60-80 million tons, instead of supporting the ultra-high temperature concentrated sulfuric acid pump liquid depth of 1-2 meters also will increase the original to 3-4 meters , so in the short axis ultra-high temperature concentrated sulfuric acid pump has been unable to meet the needs of such devices , and the long axis of the pump under the domestic ultra-high temperature concentrated sulfuric acid solution is almost zero , the product is completely dependent on imports. Foreign pump is not only expensive , long lead times, service is slow accordingly , seriously restricting the development of China's sulfuric acid industry, large-scale devices. Therefore , special pump engineers have developed under the long axis of the ultra-high temperature concentrated sulfuric acid pumps , and has applied for national patents.

        It is understood that under XDBG series of ultra-high temperature concentrated sulfuric acid long axis of the pump to pump the center of the bottom plate of 3.3 meters , the abolition of the suction pipe , greatly improve the anti- cavitation performance of the pump. Meanwhile efficiency from 80 % to 85% , up to 88% domestic initiative ; impeller XDS-9 Olympic super high-chromium nickel- based stainless steel nitrogen at 200 â„? 98% concentrated sulfuric acid corrosion rate of <0.04mm / a, is the world's most advanced high-temperature concentrated sulfuric acid corrosion resistant stainless steel ; pump, pump cover and other flow components using XDS-7-2 does not contain nickel , niobium titanium dual stable high chromium ferritic stainless steel , in 200 â„? 98% concentrated sulfuric acid corrosion rate <0.095mm / a, XDS-7-2 is a section -nickel stainless steel , in today's energy crisis of the environment, has important economic significance. Its performance range : Flow = 10-4800m3 / h; Head = 5-40m; Speed ​​= 1450,970,580 r / min.
