    Tips: How to Select a Vacuum Pump?

    Different vacuum system configurations need to be selected for different vacuum sections in order to meet the process indexes, work efficiency and equipment life requirements of different products. For optimal configuration, the following points should be considered when selecting the vacuum system:

    1. The vacuum required for each process must be checked first. Because each process has its own vacuum range, it must be carefully studied and determined.

    2. Check the ultimate vacuum of the vacuum pump based on the determination of the vacuum required by the process, because the ultimate vacuum of the pump determines the optimal operating vacuum of the system. Generally speaking, the ultimate vacuum of the pump is 20% lower than the operating vacuum of the system and 50% lower than the ultimate vacuum of the front stage pump.

    3. Check and determine the type and volume of pumping required by the process. If the type of gas pumped reacts with the liquid in the pump, the pump system will be contaminated. At the same time, the proper exhaust time and the amount of gas produced during the extraction must be considered.

    4. Check the time required to reach the required vacuum degree, the flow resistance and leakage of the vacuum pipe. Consider the extraction flow rate required to maintain vacuum under certain process requirements after the required vacuum degree is achieved.

    Would recommend to friends!
    First time use this vane vacuum pump and it is better than I anticipate. No issues to report so far. Be sure to keep the oil level high enough to prevent damage to the unit. It is worth a high rating.
