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 ultimate 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 largest diameter diffusion pump is 1600mm, and the pumping speed is 130,000 liters per second. , Is the largest production base of 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, the claw-type oil-free vacuum pump (ZB, 2ZB, 4ZB single-stage, two-stage, and four-stage oil-free pumps are the first environmentally friendly products in China) and four new products such as two-stage vertical rotary vane pumps (2XL series) have been developed recently. . 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.
