Vacuum diffusion pump is the main equipment used to obtain high vacuum (10-2-10-5Pa). It and the valve water-cooled baffle, pipeline, mechanical vacuum pump, etc. constitute a high vacuum pumping system.

The pump is characterized by fast pumping speed, simple structure, easy to operate and maintain. The pump core material is made of stainless steel, and the drawing process is adopted, which increases the strength, reduces the amount of air release, and solves the disadvantage that the diffusion pump core is easily deformed and the gap is uneven, so that the work is reliable and the use time is long. The pump adds an oil temperature measuring port to facilitate temperature control and save energy while preventing overheating of the pump oil. The oil surface observation window allows you to observe whether the oil has deteriorated at any time through the observation window. In addition, the pump wall cooling adopts a continuous welding method in which the water pipe and the pump wall are integrated, which increases the contact area and has a good cooling effect.

Vacuum diffusion pump is used in vacuum coating, vacuum furnace, electronics, chemical, aerospace, metallurgy and other fields.
