Give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Rapid Development in Chemical Engineering Equipment】Regularly updated summary posts are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Isobornol is an important chemical raw material; it appears as a colorless liquid and is widely used in the production of fine chemicals and new materials. It is an essential raw material in the industrial chain related to \"new infrastructure\". As a key refining and chemical enterprise under Sinopec, Zhenhai Refining & Chemical has a crude oil processing capacity of 27 million tons per year, making it one of the world-class green chemical hubs. However, the ultra-high flow rate and high-pressure transfer pumps required for its production have long relied on imports. To break the monopoly, Depam, leveraging its years of technical expertise in fluid handling equipment, developed this ultra-high-flow, high-pressure diaphragm pump with independent intellectual property rights. This helped Zhenhai Refining & Chemical increase the proportion of domestically produced equipment and further expand into international markets. Recently, two super-large high-pressure diaphragm pumps, independently developed by Depam (Hangzhou) Pump Technology Co., Ltd., a company located in the Qiantang area of the Hangzhou zone of the Zhejiang Free Trade Pilot Zone, were successfully manufactured. They are set to be shipped to Ningbo to equip the isononanol production facility of Sinopec Ningbo Zhenhai Refining & Chemical Co., Ltd., with \"Chinese-made components\". The completion of production of these two \"giant\" pumps, each weighing nearly 26 tons and costing over 10 million yuan, marks China’s successful break of foreign technological monopolies in the field of ultra-high-flow high-pressure pumps, representing another step forward in the localization of high-end equipment. This high-pressure diaphragm pump can achieve a maximum pressure of 270 kilograms; at this pressure, it is capable of lifting water to a height of 2700 meters ； The peak flow rate is 46 cubic meters per hour, which is equivalent to filling 154 5-liter bottles of mineral water per minute – a figure that far exceeds that of similar products. At the same time, the \"one five-cylinder unit + two units under synchronous control\" technology is employed, which significantly reduces vibration and ensures long-term stable operation. It is reported that one of the biggest challenges in the development of this high-pressure diaphragm pump was how to achieve a balance between ultra-high pressure and high flow rate. Traditional pump designs often struggle to balance these two aspects; through innovative design and repeated testing, Depam utilized unique structures and materials to successfully overcome this technical bottleneck. To ensure the high reliability and leak-free performance of its products, Depam has also developed its own patented high-sealing technology, effectively solving challenges in this industry. The market prospects for this ultra-high-flow, high-pressure diaphragm pump are extremely promising; it can be used not only in the production of fine chemical products such as isononanol, but also in various fields including oil and gas extraction, nuclear power, new energy sources, and environmental protection.
