China Industrial Screw Vacuum Pump Unit - Suppliers & Factory for Advanced Pump Solutions

The Screw vacuum pump unit features a high-performance Rotating vane pump as its main component, complemented by an LGB oil-free vane pump that serves as a pre-stage pump. This innovative setup enables the vane pump to create the essential pre-vacuum required for optimal operation of the Rotating vane pump, which functions effectively as a booster pump. Each additional stage of the Rotating vane pump, when configured in series, significantly enhances the ultimate vacuum capacity of the unit, increasing it by one order of magnitude. As a leading supplier and factory in China, we ensure that our vacuum pump solutions meet industry standards, providing reliable performance for various applications

    Explanation: The table represents the recommended standard series. Due to the varying working conditions in actual production applications, the intake gas and pressure will undergo many changes. Therefore, during the selection process, calculations should be conducted based on the actual vacuuming process, gas release process, condensation of non-condensable gases, changes in intake pressure over time, etc., or the selection should be made by referring to the usage conditions of existing equipment.

    ❓ Frequently Asked Questions
    What does "limiting pressure" mean in the JZJLG vacuum unit specifications?
    Limiting pressure refers to the lowest achievable pressure (in Pascals) that the vacuum unit can reach under ideal operating conditions. The standard series listed includes units with a limiting pressure of ≤1 Pa and ≤0.1 Pa, catering to different levels of vacuum requirements in industrial applications.
    What is the difference between models with ≤1 Pa and ≤0.1 Pa limiting pressure?
    Models with ≤0.1 Pa limiting pressure include an additional middle pump (e.g., ZJP70, ZJP150, ZJP300, ZJP600) in their configuration. This extra pumping stage enables the unit to achieve a deeper vacuum compared to ≤1 Pa models, which typically operate without a middle pump.
    How should I select the right JZJLG vacuum unit model for my application?
    Selection should be based on your specific process requirements, including the required vacuum level (limiting pressure), the volume of gas to be evacuated (vacuum extraction rate in L/S), the nature and amount of gas released during the process, condensation behavior of non-condensable gases, and how intake pressure varies over time. It is also recommended to reference the performance of existing equipment in similar applications.
    What is the role of the pre-stage pump (LGB series) in the vacuum unit?
    The pre-stage pump (such as LGB50, LGB80, LGB120, LGB150, LGB200) serves as the backing pump in the vacuum system. It maintains the outlet pressure of the main and middle Roots pumps within their allowable operating range, ensuring stable and efficient system performance throughout the vacuuming process.
    Can the standard JZJLG series models be customized for special working conditions?
    Yes. The table represents the recommended standard configurations. Since actual production environments involve variations in intake gas composition, load conditions, and pressure fluctuations, customized pump combinations or configurations can be engineered to meet specific process demands. It is advised to consult with the manufacturer and perform detailed process calculations before finalizing the selection.
    What is the maximum vacuum extraction rate available in this product series?
    The highest vacuum extraction rate in the standard JZJLG series is 2500 L/S, achieved by the model JZJLG2500-4.2. This model is equipped with a ZJ2500 main pump, a ZJP600 middle pump, and an LGB200 pre-stage pump, with a total motor power of 48 KW, making it suitable for large-scale industrial vacuum applications.
