2BV系列真空泵适用于抽除气体和水蒸气，吸气压力可以达到33mbar绝压(97%真空度)。当真空泵在吸气压力低于80mbar的状态下长期工作时，应联接气蚀保护管，以对泵进行保护。如配大气喷射器，吸气压力可达10mbar，喷射器可直接安装在真空泵上。作为压缩机用时，其压力至0.26MPa(绝压)。
2BEA、2BVA、SZ、2S、2SK系列水环真空泵，除与罗茨泵或气冷泵组成2-4级罗茨水环或罗茨气冷水环机组外，亦可独立组成水环泵闭环或开环成套机组（含防爆型）。
Model 2BEA, 2BVA,SZ, 2S, 2SK water ring vacuum pump series could be assumed into 2-4 stages vacuum pump unit with roots vacuum pump or air cooled pump and also could be water ring closed-loop or open-loop unit (include the explosion-proof type) independently.
由于气体的压缩过程是等温压缩，所以适合于抽吸、压送易燃、易爆及有毒、有味气体；
Because the gas compression process is the isothermal compression, so it is suitable for suction and pressure feed of flammable, explosive, poisonous and pungent gas.
