タイトルまたは説明

1. Liquid ring vacuum pumps are suitable for vacuum extraction of moisture, vapour, condensable gases and solid molecules.
2. The compressed heat was absorbed by sealed flued, the equivalent to isothermal compressing, thus cause lower temperature of discharged gases and insured high safety for explosible gases.
3. In internal part, no metal friction thus no lubricant is needed; totally pollution free and low maintenance cost.
4. An additional atmospheric device (air ejector) is installed at the intake port, the ultimate vacuum can reach to 6~2 torr; the unit in combination with a mechanical booster pump can save energy and increase several times of pumping volume and ultimate vacuum.
5. A noise-free, gas liquid separator can be installed at the exhaust port.
