Working Principle

 
The pump chamber is equipped with a pair of 8-shaped rotors that rotate synchronously and reversely at high speed. The two rotors generate suction and exhaust in the pump chamber while working process. The Roots pump cannot be discharged alone, and it must be used with the backing pumps (such as screw pump, rotary vane pump, water ring pump, etc.) in series.

Performance Advantages

· Stable: Small vibration and low noise during operation;
· Energy-saving: Low power consumption and good energy saving effect;
· Startup: can start in a short time to reach the ultimate pressure;
· Oil-free: Avoid oil vapour contamination of the vacuum system;
· Anti-overload: overflow valve can automatically prevent overload.
