Xin’anjiang ZJC roots vacuum pump is a kind of volumetric vacuum pump keeping a pair of 8-shaped rotors, at a certain gap, rotating in reverse direction at identical speed within the pump shell to tak

The best merit of ZJC roots vacuum pump is that it obtains a high air suction rate when the inlet pressure is low. However, the pump can’t work alone and requires a backing vacuum pump connected in series. It starts working only when the pressure of the system pumped by the backing vacuum pump matches the allowed inlet pressure of roots vacuum pump. Besides, the roots vacuum pump shall not work under high differential pressure generally, or it will be damaged due to overload and overheating, so an appropriate backing pump shall be selected for the roots vacuum pump. A protective device is required. Please note that, after the roots vacuum pump is anticorrosion treated, the backing pump, if a water jet vacuum pump or anticorrosion water-ring vacuum pump, could pump out heavy steam contained caustic gas.
