    The 2BE1 series of water ring vacuum pumps are high-efficiency and energy-saving products developed by our company on the basis of years of scientific research results and production experience, combined with advanced technology of similar international products, and market research and analysis. 2BE1 series water ring vacuum pump, working medium is clean water at room temperature, adopts single-stage single-acting structure, has the advantages of simple structure, reliable operation, high efficiency and energy saving, and can adapt to harsh working conditions such as large displacement and load shock fluctuations. The pump unit has a horizontal structure, which is convenient for users to install and maintain. According to user needs, there are direct drive, pulley drive and reducer drive.


    After careful manufacturing and perfect quality control, the products have reached the leading domestic level.


    This series of products comply with GB/T 13929-2010 and GB/T 13930-2010 standards.

  • The bearings are all imported bearings to ensure the precise positioning of the impeller and the stability of operation.

    All mechanical seals (optional parts) are imported parts, which fully guarantees long-term operation without leakage. Ran Kun Vacuum Technology (Shanghai) Co., Ltd.

    Equipped with a flexible valve plate to avoid over-compression and more energy-saving.

    Equipped with an automatic drain valve to avoid overload starting and make it safer.

    The shaft sleeves are all made of high chromium stainless steel, which has a life span of 5 times longer than that of ordinary materials.

    The pulley (belt drive) adopts a standard high-precision tapered pulley, which is reliable in operation and easy to disassemble.

    All castings are made of resin sand with good surface quality. The surface of the casting does not need to be greased, and the heat dissipation effect is better.

    When the flow parts are made of different grades of stainless steel, they can meet different anti-corrosion requirements.

    When the vacuum pump is running under high vacuum, a cavitation protection device can be installed, which can effectively improve the anti-cavitation ability of the vacuum pump.

  • High reliability and easy maintenance Rankun Vacuum Technology (Shanghai) Co., Ltd.

    1. The motor power selected above can work under most working conditions. If the exhaust port pressure is high (0.02~0.05MPa), the motor power should be increased accordingly; for example, the shaft power of the 2BE1 vacuum pump is small when it is working normally, and the motor power close to the shaft power can also be selected, which is more energy-saving.
    2. The temperature of the working fluid of the water ring vacuum pump has a great influence on its performance, and the performance curve of the water ring vacuum pump is measured at a water temperature of 15°C. Therefore, in the actual selection, the pumping rate should be corrected by the water temperature.
