        Liquid(water) Ring Vacuum Pump

        Model:2BV


        2BV series liquid (water) ring vacuum pumps suitable for pumping gas and water vapor, the suction pressure can reach 33mbar absolute pressure (97% vacuum), when the transformer oil as working fluid (called oil ring vacuum pump), suction pressure can reach 6.7mbar absolute pressure (99.3% vacuum), can be completely replace the reciprocating pump. When the liquid ring vacuum pump in suction pressure close to the limit of vacuum (working fluid saturated vapor pressure) for a long time to work, should be connected to the protection of the pipe to protect the pump. 2BV series liquid (water) ring vacuum pump as a new generation of energy-saving products, with its excellent performance and many advantages will be fully replace the same energy SK, 2SK series liquid (water) ring vacuum pump and W, WY, WL series reciprocating pump.
        2BV2-Ex, 2BV6 series liquid (water) ring vacuum pump is mainly used for pumping explosive gases, and in all kinds of flammable and explosive environment, its performance parameters and 2BV2, 2BV5 series of the same.
        Main features:
        Motor and pump coaxial direct design, saving space, easy to install, easy maintenance.
        All - are cavitation protection tube interface, such as working in the limit pressure, open the cavitation protection tube interface (or separator connection) to ensure maximum suction effect under the condition of cavitation eliminating sound, and for the protection of the pump.
        Aluminum bronze impeller and diaphragm high strength, durable, and improve the corrosion resistance of the pump. Such as over-current components using stainless steel, can work in a more demanding environment.
        Unique flexible exhaust design, will not produce over compression, to ensure that the 2BV Series in its performance range of the best efficiency.
        All use Y2 series motor, protection grade IP54, IP55 (usually IP44), insulation grade F class insulation (usually B class insulation).
        All use NTN or NSK imported bearings.
        2BV series liquid ring vacuum pump can realize all the flexible seals, which can greatly prolong the service life of the vacuum pump under severe operating conditions.
