  • Water Circulating Vacuum Pump - China

    price: contact company for price

    The series of Multi-purpose Circulating Water

    Vacuum Pump takes circulating water as

    working fluid, uses the negative pressure

    created by fluid jet to eject.

    Providing vacuum condition for the processes

    of evaporation, distillation,

    crystallization, drying, sublimation,

    filtration and decompression, degassing and

    so on, particularly be suitable for labs and

    small scale test of industries such as

    universities and colleges, scientific

    research institutes, chemical industry,

    pharmacy, biochemistry, foodstuff, pesticide,

    agricultural engineering, biological


    1. Cyclically use water, save the precious

    water resources.

    2. Save more than 35% of electricity than

    other type of vacuum pump.

    3. The fluid muffler purposemade can reduce

    the gas in water and make the vacuum degree

    higher and more stable; reduce the friction

    between gas and fluid, reduce the noise.

    4. Double-tap, double-display, can be used

    alone or in parallel.

    5. Resist corrosion by acid, alkali and


    6. The special machine is made by the famous

    electric manufacture ODM with fluorine rubber

    sealing, the inner of which can’t be

    intruded by corrosive gas.

    7. Need to replace the water in the flume

    regularly to ensure the purity of water

    quality, the vacuum degree and to avoid dirt


    8. Can be used to extract corrosive gas, need

    to shorten the period of water changing.

    SHB-Ⅲ: shell, flume, ejector, tee junction,

    check valve and gas-extraction nozzle adopt

    the PP material; pump body and impeller(six

    flow passages, dual seal) adopt stainless

    steel plate pressing, the material is in

    accordance with the ANSI standard.

    SHB-ⅢA: ejector and gas-extraction nozzle

    adopt stainless steel material (ANSI

    standard), the rest is the same as SHB-Ⅲ.

    SHB-ⅢS: pump body adopts the PP material,

    which is more suitable for acid gas, the rest

    is the same as SHB-Ⅲ.

    SHB-ⅢT: lucid flume is convenient for

    observe water level and water quality, the

    rest is the same as SHB-ⅢA.
