Roots vacuum pump

Working Principle
The pump chamber contains a pair of synchronously counter-rotating high-speed figure-8-shaped rotors. During operation, the two rotors create suction and exhaust effects within the pump chamber. Roots pumps cannot exhaust independently and must be used in series with a backing pump (such as a screw pump, vane pump, water ring pump, etc.).
Roots pumps are divided into two types: the standard DR type and the DRP type with bypass function.

Performance Advantages
· Low vibration and noise during stable operation;

· Energy saving: Low power consumption with excellent energy-saving effect;

· Startup: Capable of starting quickly and reaching ultimate pressure in a short time;

· Oil-free: Prevents contamination of the vacuum system by oil vapor;

· Overload protection: The overflow valve automatically prevents overload.
