Tow stage oil sealed rotary vane vacuum pump has two cylinder and can compress the air two times. It can generate higher vacuum level than single stage rotary vane vacuum pump. It can be applied in lab and industrial application on low or medium vacuum requirement.

· The use of non-spring rotary vane to achieve low noise, low vibration and long service life.

· Built-in oil check valve is used to reduce the oil return phenomenon.

· Built-in forced fed oil pump is used to ensure the long-term continuous operation of the pump at atmospheric pressure.

· The use of air cooling, oil cooling, water cooling and other cooling methods to ensure the good cooling effect, and make the long-term stable running of the pump as well as the stable pumping performance.

· CE certificate
