New materials, new process to speed up the use of the past decade or so, new materials and the use of new technology is to promote the development of diaphragm vacuum pump technology a major factor. Diaphragm vacuum pump to use material from the cast iron of special metal alloys, rubber products, ceramics and other non-metallic materials typical to the engineering plastics, in the settlement of corrosion-resistant diaphragm vacuum pump, wear-resistant, high temperature, such as the environment has played a prominent role. At the same time, the use of new technology and new materials to make better use of the diaphragm pump diaphragm pump parts and the whole of them. If some foreign manufacturers have designed and introduced the use of diaphragm pumps made of engineering plastics. Than using an ordinary metal materials produced on the diaphragm vacuum pump favorably in strength, wear resistance in the superior corrosion resistance. For example, they take advantage of new surface coating technology and surface treatment technology, the same diaphragm vacuum pump to resolve the problem of corrosion resistance and anti-wear. The further development of new materials and the use of new technology in depth, in the divide in the field of application of vacuum pumps will be more extensive.
