2BV type vacuum pump is used for pumping air and steam,suction pressure can be 33hpa absolute pressure (97%vacuum degree),when vacuum pump working in a long term operation with the state of suction pressure lower than 80hpa,The air erosion protection tube shall be connected to protect the pump,suction pressure can be 10hpa with air ejector.The injector can be directly mounted on the vacuum pump.When it’s used for compressor,the maximum pressure is 0.26hpa(absolute pressure).
2BV type water ring vacuum pump and compressor are widely used in petroleum 、chemical、medicine、food、sugar industry etc.During the operation the gas is compressed isothermally. If corrosive or explosive gasses are compressed or extracted no danger will occur. There fore these pumps can be used in many fields.
