Detailed Photos

Roots vacuum pump (abbreviated as Roots pump) is a rotary variable capacity vacuum pump without internal compression. It utilizes 2 8-shaped rotors to rotate in the pump casing to generate suction and exhaust effects. Its principle is similar to that of a Roots blower. Due to its operation in a low pressure range, the gas molecules have a large free range, and the resistance of gas leakage through small slits is high, so it can achieve a high compression ratio and can be used as a booster vacuum pump; But it cannot directly discharge the gas into the atmosphere alone, and needs to be used in series with the front stage vacuum pump. The extracted gas is carried into the atmosphere through the front stage vacuum pump.

Roots pumps are widely used in vacuum degassing, vacuum melting, vacuum treatment of molten steel in the vacuum metallurgy industry, as well as in devices such as space simulation and low-density wind tunnels to extract corrosive gases. It can also be used in production processes such as distillation, evaporation, and drying in industries such as chemical, food, pharmaceutical, and motor manufacturing.

The ZJ series Roots vacuum pump is a rotary variable capacity vacuum pump that requires a front stage pump to be used. It has a large pumping speed in a wide pressure range in China and is not sensitive to dust and water vapor in the extracted gas. It is widely used in industries such as metallurgy, chemical industry, food, and electronic coating.
