Two-stage water ring vacuum pump

2sk-1.5：

4kw-4

series of two-stage water ring vacuum pumps and a series of two-stage water ring vacuum pump atmospheric jet pump units are used to extract air and other non-corrosive, water-insoluble, and solid particle-free gases to obtain higher vacuum in closed containers.
< /> It is widely used in vacuum evaporation, vacuum concentration, vacuum rehydration, vacuum impregnation, vacuum drying and vacuum smelting in the fields of food, weaving, chemical, pharmaceutical and metallurgical industries and electronics. It has the characteristics of high vacuum degree, high pumping speed in high vacuum area, compact structure, reliable operation and convenient maintenance.
< /> The series is suitable for working conditions where the suction pressure is lower than the suction pressure. The series is suitable for working conditions where the suction pressure is lower than that. When equipped with an atmospheric pump, the ultimate vacuum can be reached.
< /> The working vacuum range is.
< /> < /> Compared with single-stage water ring vacuum pumps, it has the characteristics of high vacuum degree and high pumping speed in high vacuum areas
< /> Compact structure and convenient maintenance
< /> It has a wide range of applications and can extract various gases containing water vapor, flammable, explosive, a small amount of dust, a small amount of liquid and a small amount of liquid
< /> Mainly uses water as the working medium, with low maintenance costs
< /> It can be used in relatively Work in harsh environments.
