◆ SINCE 1996 ◆

Liaoning Zhenlong Vacuum Equipment Manufacturing Co., Ltd. was founded in 1996

Passed the ISO9001 quality system certification at the end of 2000. It is a contract-honoring and AAA-level credit enterprise

The registered capital of Zhenlong Vacuum: RMB 20,400,000, total assets: RMB 10 billion, and sales revenue in 2016: RMB 23,300,000. Zhenlong Vacuum Production Base is located in Shenbei New District, covering an area of ​​43,200 square meters and a building area of ​​20,000 square meters. The company has strong technical force, and the technical backbone comes from graduate and undergraduate students majoring in vacuum at Northeastern University. The processing equipment and testing methods are complete. There are processing centers, special processing equipment and various vacuum pump test benches that meet national standards. The performance of products produced by Zhenlong Vacuum can be fully tested in the company.

The company’s leading product is vacuum acquisition equipment, with three major parts (oil booster pump, water-cooled baffle, and pneumatic baffle valve) as the core of the diffusion pump, expansion pump, and oil booster pump. The expansion pump and oil booster pump vacuum unit have the characteristics of high vacuum, high pumping speed, low oil vapor return and stable operation in the high pressure section. There are currently 103 models of oil diffusion pumps K, KT, KA, KC, KN, KTN, oil expansion pump ZKT, oil booster pump Z, eight series, the larger diameter diffusion pump is 1600mm, and the pumping speed is 130,000 per second. Sheng is the production base of large-diameter diffusion pumps, expansion pumps, oil booster pumps and various vacuum units at home and abroad. The supporting products for the front stage of the vacuum unit of diffusion pump, expansion pump and oil booster pump include: slide valve vacuum pump (H series), roots vacuum pump (ZJP series), rotary vane vacuum pump (2X series), high vacuum pneumatic baffle Valves (GDQ series), high vacuum flapper valves (CC, CCQ, CCD series), vacuum differential pressure valves (DDCY series) and water-cooled baffles (SDB series), etc.

Diffusion pump, expansion pump, oil booster pump, vacuum valve and water-cooled baffle are all manufactured by drawing process. Diffusion pump, expansion pump, oil booster pump are equipped with oil level observation window, oil filling and draining ports, temperature measuring ports and multiple heaters in parallel combination. The heaters can be replaced without stopping, and the pump oil temperature control can be configured according to user needs Overheating protection device.

Recently, we have developed four new products including claw-type oil-free vacuum pumps (ZB, 2ZB, 4ZB single-stage, double-stage, and four-stage oil-free pumps are domestic environmental protection products), and two-stage vertical rotary vane pumps (2XL series). Mass production was put into the market in 2008, and Zhenlong Vacuum is the largest manufacturer of steam flow vacuum pumps in the same industry in China.

The company's products have been widely accepted in the domestic market and are used in high-tech fields such as food, medicine, electronics, metallurgy, materials, sponge titanium, metal magnesium, biology, chemical industry, aviation, aerospace, and space technology. Provide diffusion pumps, expansion pumps, oil booster pumps, vacuum valves, water-cooled baffles and vacuum units for titanium and zirconium production enterprises. The domestic market share is 60%, and the output of diffusion pumps with diameters above DN800 is above 90%. There are hundreds of fixed-point supporting users, and the supporting vacuum furnaces, coating machines and other products have been exported to more than 20 countries and regions such as Europe, the United States, South Korea, Japan, Taiwan, Malaysia, Singapore, and Pakistan. The general manager of the company has visited Europe, the United States, South Korea, Japan, Hong Kong, Southeast Asia and other countries and regions, and learned and learned the advanced management concepts and vacuum science and technology of foreign companies, and promoted the development of the company.
