Roots water ring vacuum unit

The Roots water-ring vacuum unit is a vacuum unit composed of a Roots pump as the main pump and 2BV or 2BE water ring pumps as the pre-stage pumps. The function of the water ring pump in the unit is to obtain the necessary pre-vacuum for the Roots  pump. The role of the Roots pump is to be used as a booster pump. For each additional stage of Roots pumps connected, the ultimate vacuum degree of the vacuum unit can increase by one order of magnitude.

    Explanation: 1. The series in the table represents the recommended standards. Due to the varying working conditions in actual production applications, the gas intake and pressure will undergo many changes. Therefore, during the selection process, calculations or reference to the usage of existing equipment should be conducted based on the actual vacuum extraction process, gas release process, condensation of non-volatile gases, time variations of the intake pressure, etc.

    2. The technical indicators of the single pump are detailed in the respective pump parameter tables.

    3. The maximum intake pressure refers to the highest pressure that the main pump can start at. If it operates for a long time at a pressure higher than this, it will cause the main pump to overload.

    4. If the vacuum pump motor, electrical contact vacuum gauge/pressure transmitter, and electrical control cabinet need to be explosion-proof, please specify during the order. The 2BV5 water ring vacuum pump in the table should be correspondingly changed to the 2BV6 series.
