GW-5
1.Suitable for vacuum extraction of moisture, vapors, condensable gases and particulates.
2.The compressed heat was absorbed by sealed fluid, equivalent to isothermal compressing, thus cause lower temperature of discharged gases and ensured high safety for explosible gases.
3.Due to no metal friction in internal, 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 6~2Torr; series connected with a mechanical booster pump can conserve 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.

‧ Single stage model ideal operation range of 160~760 Torr.
●Performance testing conditions of Liquid Ring Vacuum Pumps as below:
‧ Experimental conditions for gas discharging function listed on the catalogue include: inlet air temperature is 20℃, outlet pressure is 760 Torr, relative humidity is 75%, and sealing fluid temperature is 15℃. In case the actual sealing fluid temperature is higher or lower than 15℃, please modify it in accordance with Modification of Gas Discharging Function Table. Please avoid exceeding the red line zone to prevent from cavitation and noise.
