Roots Vacuum Pump

 
Roots Vacuum Pump

1. High efficiency, low power consumption, small size, light weight, little vibration and low noise

2. Appropriate structure, functioning effciency, easy maintenance and high reliability and durability

3. ZJP Roots Vacuum Pump with the overload protection and the wider working range


APPLICATIONS:
Widely used in production and development of new materals,new technologies new process for vacuum coating,vacuum metallurgy, vacuum heat treatment,vacuum impregnation,vacuum drying, vacuum disillation,vacuum kneading,aerospace simulation experiments.
Roots Vacuum Pump cannot be used individually. It can be used with the vacuum system which composes of the backing pump such as Rotary Piston Vacuum Pump, Screw Dry Vacuum Pump, Rotary Vane Vacuum Pump and Water Ring Vacuum Pump in order to reach a better vacuum, higher exhausting efficiency,lower power consumption. Roots Vacuum Pump is not sensitive to dust and steam,so is suitable for pumping with a small amount of dust and the gas containing more steam.As the chamber of Roots Vacuum Pump is lubrication-free,the vacuum system will be polluted by oil;it is combined with Screw Vacuum Pump to compose oil-free vacunn system, which can be widely used in electronics, medicine, chemical industry, food, coating , metallurgy ect.

Note: The displacement ratios selection, so called“matching”, between the Roots Vacuum Pump and the backing pumps which are based on the working vacuum value of the vacuum system with these pumps, which not only ensure that the max pressure difference should not exceed “Max.Allowed Pressure Difference”under long term running, but also must guarantee the Roots Vacuum Pump being in a larger working range, as well as the backing vacuum pumps working properly.
