  • Company Profile

The series ZJ Roots vacuum pump is without overflow valve. The figure-of-eight rotors are counter-rotating at a constant speed inside the pump housing for suction and exhaust of gas. Two rotors are supported by two bearings and synchronized by a pair of gears, which ensure these two root ors in certain relative positions. They are near to one another and to the housing without actual contacting, so lubrication is unnecessary in the working housing. The carefully balance operating parts and high precision bevel wheels ensure the pump be operated stably and continuously under the condition of high-pressure difference. Dynamic seal parts use our patent technology and imported oil seals. The vibration of shaft at the shaft seals is controlled to less than 0.02mm against oil leaking.
