The DVB series Roots vacuum pumps cover an intake volume range from 250 to 3000 m3/h. The Roots pump is an excellent device for extracting large volumes of air and can significantly extend the performance of other vacuum pumps, meaning faster pumping speed and higher vacuum degree. The oil tank and pump chamber in the Roots pump are separated, so the rotor’s rotation is non-contact and completely dry. What’s special is that our pump can use mechanical seals to completely seal and isolate. The Roots pump operates under relatively low pressure and does not expose to the corrosive process medium of the same concentration as the preceding pump, which is very reliable. Therefore, it is very suitable for medium and low vacuum applications in industries such as chemical engineering, petroleum, plastics, semiconductors, coating, and food, as well as vacuum furnaces. It can be used in series with slide valve pumps, liquid ring pumps, rotary vane pumps, and dry vacuum pumps to increase the working pumping volume, shorten the pumping time, and improve the ultimate vacuum degree. We can provide the design and products for special application solutions. We are also happy to help you design your vacuum system. With reliable products and decades of application experience and professional technology, we are always ready to provide the best solutions for medium and low vacuum applications.

DVB 系列罗茨真空泵涵盖了从250到 3000 m3/h的吸气量范围。罗茨泵是极好的可以抽吸很大气量的真空获得设备,可以极大的延伸其它真空泵的性能,这意味着更快的抽气速度及更高的真空度。罗茨泵中装轴承及齿轮的油箱和泵腔是分离的，所以转子的运转是无接触和完全干式的。特别的是我们的泵可以选用机械密封来完全地密封来隔离。罗茨泵在相对较低的压力下工作，不会暴露在与前级泵相同浓度的腐蚀性制程介质下而非常可靠。因此它非常适合于化工,石油,塑料,半导体,镀膜,以及食品,真空炉等工业的中低真空应用。它适合与滑阀泵、液环泵、旋片泵和干式真空泵串联成机组使用，用于提高工作抽气量缩短抽气时间,提高极限真空度.我们能为您提供特殊应用的解决方案的设计和产品。我们也很乐意帮助您设计您的真空系统。凭借可靠的产品和数十年的应用经验及专业技术，我们时刻准备为您提供中低真空应用中的最佳解决方案。
