2BV(SKA) series vacuum pump is used to pump gas and vapor, which suction pressure reaches 33mbar absolute pressure,(97% vacuum percentage). When the vacuum pump is operated under suction pressure lower than 80mbar for a long time, it need connected gas corrosion pipe to protect the pump. When an air ejector is equipped, the suction pressure can...

The 2X series vacuum pump is of two-stage structure, its operation performance consists of two parts, high-pressure stage and lowpressure stage. Its suction port is connected with the vacuum container or other vacuum equipments to helps intaking or draining the gas inside the container during operation. When the equipment is in vacuum, the...
