ZJ-300A Roots vacuum pump

Roots vacuum pump is equipped with a pair of synchronous reverse high-speed rotating 8-shaped rotor in the pump cavity. When working, the two rotors produce suction and exhaust in the pump cavity. This type of pump can not be alone exhaust, must be used in series with the front pump (such as slide valve pump, water ring pump, oil ring pump, etc.).

This type of pump is divided into ordinary ZJ type and ZJP type with relief valve.

This type of pump is widely used in vacuum coating, chemical, food, medicine, smelting, motor manufacturing and other industries. Especially when the two-stage water ring pump is used in the front stage, it can remove the gas containing a large amount of water vapor, so it is very suitable for distillation evaporation, freeze drying and other production processes.

特点Characteristic：
-Stable operation, low vibration and low noise.
-Low power consumption and good energy saving effect.
-Start fast, can reach the limit vacuum in a short time.
-The pump cavity does not need to be lubricated with oil, which eliminates the pollution of the vacuum system by oil vapor and is not sensitive to tiny dust.
-The ZJP pump is equipped with an overflow valve, which has the function of automatic overload prevention.
