1. High pumping speed at low inlet pressure, low energy consumption.
2.ZJB with relief valve Roots vacuum pump is a derivative of ZJ type. (With overload protection, can be started at higher pressure)
3. Can not be used alone, must reasonably select the pre-stage vacuum pump.
4. The front vacuum pump can choose oil seal mechanical pump, water ring vacuum pump, slide valve pump, oil-free screw pump, etc.
5. It is not sensitive to dust and water vapor contained in the extracted gas.
1. No oil in the pump chamber, no pollution to the vacuum system, improve product quality.
2. There is no oil in the pump chamber, which can solve the problems of oil emulsification, frequent replacement of working fluid, frequent pushing and maintenance, and save the use cost.
3 Dry operation, will not produce waste oil and smoke, will not produce waste water, is conducive to environmental protection, saving oil resources and water.
4. The limit vacuum can reach 5Pa, or even higher, and Roots pump, molecular pump in series can form an oil-free unit. Can remove a large amount of water vapor and a small amount of dust gas.
5. After the anticorrosive coating is treated, a variety of corrosive media can be pumped out, which is commonly used in chemical and pharmaceutical processes for product distillation, drying, degassing, etc.
6. The pumped gas is directly discharged from the pump, without water and oil pollution, and gas solvent recovery is more convenient.
7. Easy to clean, such as the pump cavity into the pollution need to be cleaned, just open the pump suction and exhaust port, open the pump from the suction port to add an appropriate amount of water or cleaning agent, that is, the pump clean, without disassembling the whole pump.
