On November 11th, Sinopec Tianjin Nangang's 1.2 million tons/year ethylene and downstream high-end new materials industrial cluster project was successfully started, the entire process was completed, and qualified products were produced. This marked that Sinopec Tianjin base had been one of the largest Sinopec ethylene industrial bases, which would drive the development of hundreds of billions of downstream industries, promote the development of Tianjin's fine chemical and new materials industries to be at the forefront of the country and contribute to the coordinated development of the Beijing-Tianjin-Hebei region.

In this project, Yantai Longgang Pump Industry Co., Ltd., a joint venture of Dawn Group, as a key equipment supplier, provided 12 sets of advanced LDT (VS6) vertical barrel pumps, including high-pressure ethylene feeding pumps, low-pressure ethylene feeding pumps, hydrogenation AGO transfer pumps, PPT device delivery pumps and propylene loading pumps. It is reported that these equipment have long relied on imports. Longgang Pump Industry Co., Ltd. continuously achieves technological breakthroughs in this field and sets an example for domestic equipment to replace imports.

As a national "little giant" enterprise specialized in special and new technologies and a gazelle enterprise in Shandong Province, Longgang Pump Industry Co., Ltd. has been deeply involved in the petrochemical, coal chemical, environmental protection and other industries, and mainly produces three series of centrifugal pump products of API standard OH, BB, and VS. Among them, core products such as BB2, BB3, and VS6 won wide recognition from customers with their excellent safety, stability, high efficiency and energy saving. The company has provided a large number of key pump equipment in the fields of large-scale oil refining, ethylene production, coal gasification, coal liquefaction, coal-to-methanol and coal-to-olefins, and has made important contributions to the development of the industry. It is a qualified supplier for well-known companies such as Sinopec, PetroChina, CNOOC, Wanhua Chemical, Yulong Petrochemical, and Lihuayi Group.

It is reported that Longgang Pump Industry Co., Ltd. independently develops the LDT vertical barrel bag pump with a first-stage impeller sinking and secondary impeller lifting structure, which increases the insertion depth of the pump and improves the operating stability of the pump. It is widely used in petrochemical, coal chemical, cryogenic engineering and nuclear power fields. It is particularly good at transporting easily vaporized and low-temperature media such as ethylene and propane. It plays an irreplaceable role in many links such as synthetic ammonia units, ethylene units, propane dehydrogenation projects and liquefied gas transportation.

In February 2017, Longgang Pump Industry Co., Ltd. was listed on the National Equities Exchange and Quotations. With excellent product quality and product energy efficiency, the company won the first prize of China Machinery Industry Science and Technology Progress, the first prize of Zhejiang Province Science and Technology Progress, Shandong Quality Brand and other awards. In the next step, Longgang Pump Industry Co., Ltd. will use advanced design concepts to continuously overcome bottleneck technologies, build a first-class domestic high-end pump brand, and promote China's pump industry to the world.
